Hey guys....it has been awhile.Hope everybody is doing ok...I have a 2012 vw Passat 2.5 in here that came out of the auction as a wreck.He had somebody fix the body damage which was front end and drivers door replaced.the power door locks do not work and there is no power to the stereo.I have checked all the fuses and can't get any power to the locks or the stereo.wondering if you have any ideas what I can check or a wiring diagram for the power door locks. thank Jim

Sure Jim, here it is. I also included a PDF for radio also. Might seem something in common there.

 

[Jim Fairbanks]

Thanks Nick.i will check it out and hope I can find out why they don't work...Jim

 

[nickb2]

Yeah, when a car gets bent a bit, some chassis grounds get moved around. When I chase electrical gremlins on a car after a fender bender, I usually check out all the grounds to chassis in that area. Tighten them down since they move under impact. A harness will either snap or bend. But chasing a ground choke point is difficult.

Try to follow the ground choke points that share the common radio and door locks. They may be on left kick pillar.

Driver door switch ground is confirmed at G639 left kick panel, radio ground is G610 I think behind center console. Anyway, power is not at all on same B+ line.

You could give all those components a proper ground to each and they would work regardless, but tracing the B+, should be easy with those wiring I gave up.

Hope you liked my upgrade from white on black I used to post.



Hope you keep busy, it is important to do so.

thanks...I checked all the fuses and everything is good..I will check the grounds. I haven't figured this thing out yet....Taking a couple days off the Dr. said he thinks I picked up a virus somewhere, so I feel like crap right now.Thanks for the diagrams....Jim

 

[Jim Fairbanks]

Hey Nick....I checked the grounds and they are ok....still no door locks or stereo....can you send me a diagram of the fuse box under the hood...I don't have a diagram of what the fuses are..I keep blowing one of them and a little smoke from under the drivers seat from the metal box or module (not sure what it is)....i guess when they did they body work they replaced the drivers door from a donor car...Not sure but he thinks they used they wiring harness and module from the donor car....and the original one is gone....I have had a problem awhile back from another car...don't remember what it was,but things wouldn't work with the donor module had to use the one from the car originally....maybe it can't see this module....Jim

.Not sure but he thinks they used they wiring harness and module from the donor car....and the original one is gone....I have had a problem awhile back from another car...don't remember what it was,but things wouldn't work with the donor module had to use the one from the car originally....maybe it can't see this module....Jim

This would explain alot.

But not the radio.

I will check tommorow on a co workers car, he has almost same model car. I will plug in my scanner to see if there is a driver door module reset/reflash available.

 

[Jim Fairbanks]

Thanks Nick.....If you get a chance send me the diagram for the fuses in the underhood box so I can see which fuse is blowing...thanks...Jim

 

[Jim Fairbanks]

Hey Nick....If you get a chance would you please look up a diagram of the underhood fuse box for me...thank you...I appreciate the help....Jim

 

[nickb2]

well sure I can provide that, but I am scared I don't have exact wiring model. Europe cars a very specific. SO which 2.5l do you have? Also, is it a standard?

Here is power distribution for every fuse in that passat, for a 2.5l auto engine vin H.

But if your engine is a 2.5l vin# P with a manual, that will considerably change the wiring. Anyway, hope this pdf helps.

You were an immense wealth of info back in the day before your wife got sick. So paying that back to you is more than fun for me. It is a privilege. I am sorry I missed your monday message asking same thing, I am super swamped at work. It spring time, everybody is flooding to the shop.

 

[nickb2]

Oh, also, no driver module reset or such available. Checked on the co worker car. Very straight forward cheap german engineering.

 

[Jim Fairbanks]

Hey Nick....It is a 2.5 ..VIN3...automatic....Thank you...Jim....and thank you for your friendship...

 

[Jim Fairbanks]

By the way....I don't know if I told you but it keeps blowing one fuse...that is why I need to know which one it is...no diagram on the lid...Jim

 

[Jim Fairbanks]

If you have a diagram of where the fuses are it would help because they are not numbered so I can't tell which one is #1 and so on...Jim
