Title: Door Switch not working
Post by: mnkyman on February 15, 2012, 07:58:56 PM
My right, front door switch does not recognize when the door is open. (LED won't turn on while other doors do and the car allows me to lock the doors when the door is open). I couldn't find a fuse specific for that, so I called up my local stealership to see if they could help. The service guy basically said it's either the switch or the circuitry and that there is no fuse for the circuit (something I find peculiar and possibly incorrect). The switch is a little difficult to get to since it's behind the rubber grommet and the guy noted those are easy to tear so I didn't want to go full force on it. He also said it would be about $100 for parts + labor to fix it...ugh

The switch went out after I was screwing with the LED and shorted across the LED socket leads with a screwdriver, therefore, I'm guessing it's not that the switch or circuit has gone bad, but a fuse has been blown.

Can anyone provide some insight on this? I really don't want to pay the $100, but I cherish the safety factor of knowing when a passenger hasn't fully closed a door.

You checked the fuses and didn't find anything wrong...so i say replace the switch and see if it works, if not troubleshoot from there. It's $12 from the dealership. It's just a screw or two holding it on, super easy to do and cheap. That's what was wrong with my car.

Also that guy is bullshitting you, your probably not going to tear the grommet. Buy the switch and try it out

Well that's the thing, I don't know if there is a fuse specifically for that. I did check a few of the fuses that I thought might control that down by the footwell, but they were all good. Well if I can get to the switch, I can just shortwire across the terminals to see if it is working. So have you actually done the replacement? And did it work after that?

The grommet seems like it might be glued to the vertical door frame. There is one large bolt however, so maybe I need to remove that first. But ya $12 wouldn't be bad at all, $100 sucks...do you have the part number for the switch? If it is the switch, my guess is that it has a built in fuse or relay that blew when I shorted it.

Sorry I dont have the part # I just went to the dealer and they had one in stock.The door switch is located on the door frame it is a little button that gets pushed in when you close the door. Your in luck because I have two photos from a while back when I changed mine here is the door switch

(http://i77.photobucket.com/albums/j51/rushzer0/161c0bb8.jpg)

And if you pop up the little grommet..

(http://i77.photobucket.com/albums/j51/rushzer0/ddc2d809.jpg)

You will find the single bolt/screw holding it in. Remove this and pull the switch out, wiggling maybe needed but don't yank it out as there is a connector with wires connected to it. Disconnect the connecter BUT BE CAREFUL letting the connector fall back in the hole and retrieving it can be a pain. Plug in your new switch bolt it back on, push your grommet back over and your done.

Honestly I would just buy the switch and try it. It's cheap and your problem sounds exactly like mine was.

Edit: Yes I have done this, with great success :)

Sam, we gotta get you up to speed on some stuff.  You're familiar with the Chinese proverb, "Give a man a fish and he eats for a day, teach a man to fish and he eats for a lifetime.", right?  It's time for you to learn how to fish.

Whenever I need to find a part number, I go to the Majestic Honda site (even though I don't buy anything from them) and find the part number that way.  They started using Honda part numbers, so it's a good place to search for stuff.  It's pretty self explanatory, but just go to www.hondaautomotiveparts.com (http://www.hondaautomotiveparts.com) and put in the info about your car and start searching.  It shouldn't take you more than 5 minutes to look up.  That's how long it took me.  (Hint: look under "Combination Switch")

You should know that there is no fuse for the door switch.  It is a switch that grounds to the chassis and completes the circuit to turn on the light.  The switch only requires 2 tools to remove, and a 1-3" piece of 20-16 gauge primary wire to test it.  It will only take about 5 minutes to test and replace.  The tools you need are a small flat blade screw driver and a ratchet with an 8mm socket.  Here we go:

1. open your door and locate your door switch in the b pillar
2. open up the rubber flap that's covering the screw with the small flat bladed screw driver
(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0415.jpg)
3. use the ratchet with 8mm socket to remove the screw (don't use a phillips head screw driver because you may strip the screw and have to buy a new one)

(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0417.jpg)
4. remove the door switch from the b pillar
(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0418.jpg)
5. disconnect the wire harness from the switch (hold on to the harness so it doesn't pull back into the hole, the wire is short)
(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0419.jpg)

(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0421.jpg)
6. take the piece of primary wire and slide it into the connector of the wire harness
(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0422.jpg)
(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0423.jpg)
7. ground the other end of the wire to the chassis where the screw hole is
(http://i58.photobucket.com/albums/g274/timot_one/Accord%20Pics/Mechanical/Door%20Switch%20Replacement%20And%20Testing/IMG_0424.jpg)
8. turn your key switch to the on position and see if the light works
9. if the light works, it's the switch, and replace it with a new one and follow steps 1-5 in reverse.

Nice, I've gotta try this out

Sam, we gotta get you up to speed on some stuff.  You're familiar with the Chinese proverb, "Give a man a fish and he eats for a day, teach a man to fish and he eats for a lifetime.", right?  It's time for you to learn how to fish.

LOL ya man...I'm kinda lost on car stuff...haven't done anything to my car in so long and just got back into it.

Forgot about Majestic's site, it's nice! I went ahead and ordered the switch (along with wiper blades i've needed...tired of waiting for autofair and majestic's prices were better than everywhere else).

Thanks for the pics man, this might as well be a step-by-step diy! Did you end up having to replace your's and just end up taking pictures? lol
As I noted above, went ahead and ordered the switch (at ~$4...not worth fretting over). Will try the wire trick tomorrow!

As it turns out, Ryan at AFH was on vacation.  He got a hold of me Sunday night to let me know.  That's why he hasn't gotten back to you.  I still haven't gotten my price quote for the parts I need yet either because he's been busy catching up.

As for the pics, I saw this thread and know how easy it is to replace, so I just went out to the garage and did it to take pics.  I've never had to replace my switch.  It was just so easy to do that I thought I would take pictures to post in here.  Took me about 10 minutes to pull everything apart and put it all back together while taking pics.  This stuff isn't that hard Sam.  Just have a little confidence in your abilities.  Don't make things out to be harder than they actually are.

That was nice of you! Thanks man I really appreciate it! Ya, I just like having as much info as possible going into a project; especially after a stealership says don't break that piece or it will cost $100 lol. The other thing is at my current apartment, the parking situation sucks (it's outdoors and the spots are tiny) so just to do what you did above, I would have to move my car down the street to be able to open the door far enough lol. I actually already went ahead and stripped some wire to test the switch tomorrow morning when, hopefully, my neighbor has left for work.

Sam, I know how it is.  For years I worked on my car outside when I lived in MA.  The reason why I took the pictures is because I wanted to show you how easy it was to test and replace the switch.  If I can do the work, take pictures, and write up a DIY in like 20 minutes, it's a good sign that it's easy to accomplish for anyone with thumbs.


Title: Re: Door Switch not working
Post by: mnkyman on February 16, 2012, 12:56:19 PM
Thanks man! I could have probably figured it out but the picture tutorial was nice!

I tried the short method to test the switch this morning to no avail :(. Are y'all sure there is absolutely no fuse for this? Also, must the LED part of the circuit be complete for this to work (ie: in series or parallel?) I had the LED in but it might have been backwards (ended up flipping it and trying again and still nothing). I also attempted to measure for voltage across the switch circuit and the frame and the voltometer showed nothing, but it's batteries are dieing so I can't say that for certain. This is getting quite frustrating...

I'm quite certain I shorted the circuit originally, which would lead me to believe I blew a fuse or equivalent electrical component (such as the switch)...but so far searching for the blown part of the circuit has give me no results.

I don't have an 06-07 service manual, but I can check the wiring diagrams that I have for the 03-05.

that would be great! At the moment, short of pulling and checking every fuse, I'm at a loss of what to do. The one thing I haven't checked is the underhood fuse box...but I doubt that has interior electrical components hooked up to it.


edit: also dropping this picture in here for future reference (i did check fuse 8 and it was good...to further confirm, the rest of the door locks went out when that fuse was pulled)

I'll search through that stuff later tonight when I have time.  Following the wiring diagrams in the service manual is somewhat tedious and time consuming.

I've been a bit busy with work for the past few days. I'll see if I can search the wiring diagrams I have before I go out of town. If not, I'll bring them with me. I'll have nothing better to do at night when I'm not working.

Sam, I'm not saying this to insult you.  You will not be able to follow these circuit diagrams.  It takes me a long time to follow them, and I know a little bit about wiring.  Actually, they're a bitch to to read.  I also only have physical copies of these wiring diagrams.  All of my digital copies are for other cars like the CL9, DC5 and EP3.

no worries man, note the lol at the end of my previous post. although I was pretty good at circuits in college physics, i'm guessing those have nothing on these lol

The circuit diagrams that I used when I was taking my MECP classes were nothing compared to the Honda diagrams.  The hard part that I have with these wiring diagrams is that they span across multiple pages to follow one circuit.

So from looking at the TSX wiring diagram you emailed me, on Page 43, listed as "page 61" each door looks to actually have it's own fuse for the switch. I know it won't be the same for the accord, but I'm hoping it's similar in the fact that there will simply be a fuse I can replace and not have to pay $100 to the stealership! I'm going to try to take a look at the under hood fuse box and see if there is anything regarding doors in there. Does anyone know what the abbreviations for the first four fuses (top left) are in this picture:

IGP = (PGM-FI ECU) (ECM/PCM)
P/W RR-L = Driver's Side Rear Power Window
P/W RR-R = Passenger Side Rear Power Window
P/W AS = Passenger Side Front Power Window

I attempted to try to wire check of the door switch again, this time flipping the LED both ways...but this yielded nothing. Also, checked the underhood fusebox and found nothing there either.

Sorry I haven't had a chance to help you yet Sam.  I've been crazy busy.  I was only home for 1 day last week.  I just got back last night, so I should have a chance to try and read through the wiring diagrams this week.

No worries man, I appreciate all the help! I try to give it a once over every couple of days, but I have honestly just ran out of ideas.

I definitely want to fix this (gf didn't close the door all the way and I was still able to lock the car, luckily I noticed before walking away, preventing a chance for theft), but again...$100 from the dealership just seems steep for this fix.

Honestly this sounds exactly like my problem I even had sparks fly out of the socket for the LED (oops!) trying to find the cause and it didn't hurt anything.

Have you tried buying a switch and trying it yet? It's cheap and I'm sure it would fix your problem. If you don't want to buy a switch just take off the passenger one and plug it into the drivers connector and see if it works, if it does you need a switch.

Ya I bought and received another one the other day, but figured if the wire trick doesn't work then what's the point. Upon further inspection, I can see the switch itself has no fuses, resistors, or anything that can short...it's a open/close switch in the most simple of terms. With that said, I did spend the money to buy a switch so I might as well say fuck it, and just try it out. Will report on results tonight!

edit: will post results tomorrow, it's raining here

Okay.  First, the light shouldn't have anything to do with this problem.  It will not affect how your door switch works.  I've been reading through a few things and here's what I'd suggest you do.  If you have a digital multi meter, take it out and follow these steps:

remove the left kick panel to get access to the cabin fuse/relay box
remove the 14 pin connector from the fuse relay box
check for damage to the connector and wires
check the light green/red wire in cavity 12 on the connector for damage (that's the wire for the passenger door switch)
reconnect the 14 pin connector
test again, and if it doesn't work continue on
with the door open check for voltage to ground on the light green/red wire
if you don't get 1v or less, it's either the switch or a damaged wire

That's about it Sam.

Thanks Tim! I'll check out the connector sometime this week, hopefully that fixes it. If not, I'll be back in Houston in ~2 weeks, where I left my multimeter and will be able to check out the problem further.
