Recently, at the same time, all four windows, both sunroof windows, and lights on gear shift box have totally gone out. Could this be the ECU? Any thoughts/recs on how to troubleshoot... :S

 

Best troubleshooting tool is RAVE with electrical wiring diagrams, to find the common fuse or relay or electronic module.

 

You just posted that you had some water ingress issues recently, right? That's the issue. It's getting in connectors or fuse boxes and causing the issue

 

Yes, that was me.... I took out the driver's side fuse box, see pics - looks like some corrosion to me but I'm no expert with electronics

 

Oh man, watching. I'm dealing with some weird electrical things myself. Hope you get some of the experts in here to help you out.

 

@WastedAccounts these diagrams have been helping me... I'm investigating the center console next....

 

@PNW_disco2 Thanks, my issue is a bit different then your's but I'm very suspect of my cabin fuse box since my sunroof have been leaking since before I purchased it. My thread if you are interested. Did you clean up yours and that didn't help I assume?

 

Yup, sounds like a similar issue. Awesome, I'll follow your thread. I haven't cleaned it off yet or tried to reinstall it. I'm considering purchasing a new box because it was such a PITA to take out that I shudder to think about having to put back in then take it out again..... And I'm also deep in the midst of the dreaded head gasket repair, so the electrical voodoo is on the back burner... I remain suspicious of the center console LOL

 

That fusebox. Even though it doesn't look bad, it has a few spots of medium / noticeable corrosion. I'd bet on that.

I think you'll drive yourself mad with wiring diagrams because nothing will actually make sense (went thru this on one for awhile years back).... if you don't first replace the fusebox.

 

@nashvegas Thanks!! will replace for sure
