I've read all the tech write-ups on rear window issues but haven't found my particular issue (At least I don't think I have). Have had the '89GW for about 2 months now. The rear window key switch worked fine when I got it. Dashboard switch worked too.
About 2 weeks ago the rear key switch would lower it or at least work for 3-10 seconds. At that point I couldn't get the window back up from that switch. Also, the power door locks, rear wiper and power seats stopped working. The dash switch continued to work without issue.
After a few minutes, everything begins working again. At least until you do the rear key switch again.
This weekend, all those things stopped working without the doing the key in the rear switch. I pulled the breaker/relay out of the fuse box and it was so hot, it burned the tip of my finger (Have blister to prove it).
Dashboard switch continues to work.
My gut is that there is a major short in the wiring somewhere in the tailgate, yes? Or could the rear key switch contain the short? Please let me know what I should be looking for...I don't want to take the whole thing apart if I don't have to
Thanks for any advice...
