Sunroof and back window quit working. Wondering where I can find wiring diagram for sunroof. I want to start checking there because it the easiest to get to. Or maybe someone has had the same problem and can give me some ideas.

 

If you have a copy of the owner's manual, you will find a section in there with a diagram of the fuses and relays AND what they protect.
That can save you a lot of time and trouble tracing.

ANYTIME ,,,,,,,,,,,,,,,a section doesn't work, loses power, we check all the fuses Always ,,,a good place to start.

If you find a blown fuse, replace it with the same rating fuse and things work , great ! Most times there is a reason the fuse blows.and if it blows again the reason is the circuit has excessive current draw and that could be a short to ground or an internally defective component that circuit is supplying..

 

 

Thanks for the quick response. It seems I have power to the switch. I will run all the checks later when I get some extra time. Meanwhile I can't find anything thing that ties the sunroof to the rear window motor. Any thoughts? These both quit working at the same time.

 

Both using same fuses and on the same circuits. You have 3 fuses to check: F1.47A-20A, F1.39-10A and F1.10-20A.
Locate circuit 193 (YE/LG) and 296 (WH/VT)

 

Thanks guys.I know what the problem is, I just have to find it. YE/LG from junction box to sunroof motor has a open in it. Oh joy. Wish me luck.

 

Now I remember why I quit mechanicing years ago.

 

A suggestion,,,,,,,,,,,,,,as mentioned, both stopped working at the same time.

You need to do some real checking ,,on paper, .What you should be looking for is, what do these 2 functions share/have in common ?

That means look for a ground and power supply that feeds both and studying the diagram will/should provide that, it will take some time, but I believe that would be the better way to proceed.

 

Hanky I figured out what is wrong. I have an open in one wire to the sunroof motor. I just have to find where the open is.

 

hanky. I used a jumper wire from 12v power to yellow/light green wire at motor and everything functions as it should,both sunroof and back window.
