Hope this doesn't get too long-winded, but here goes.
*First issue: New brakes, all around, late last Summer. Home-style bleeding, with no issues. Towed all the way to Texas, last Fall, and back, this Spring. No braking issues, but, the check brake system light came on several times over that period. Shut off, restart, and go on my merry way. --- Son borrows truck to tow old Avion TT to eastern NY and back, some month or so ago. Coming back down to Lake Champlain on long downhill, coming home, nearly lost it, with no lock-up in lower gears in tow-haul, and brakes fading! SES light on and service brakes flashing. Cool-down saw return to braking and normal transmission action.
*Three weeks ago: Getting ready for new paint at Maaco. Let some water down inside of driver's window. Driver's window stopped working. Checked fuses and circuit breaker. All okay. Took out driver's door switch panel/module. Took a chance and separated plastic panels. One conductor under neoprene (or whatever it is) button/contact diaphragm thingy showed some black, so I thought that I'd fried it. Cleaned it off with a really easy application of a soft eraser and then checked the conductor with a VOM. Good conductivity. Re-assembled. Now, ----- no window action, no mirror action, no lock action, AND, the dang seat heat won't shut off! Other 3 doors will lock with DL button on passenger side button. Radio won't turn off when I open the DS door with key out, but open any of other 3, and it turns off. So, the DS control panel isn't "talking" to the body control module, but the PS door seems to be working normally.
Here's where I'm at, at the moment. Got the truck back from Maaco, and it looks like a brand new truck. I had removed almost everything, to allow them to do a better job, and they seem to have done so. I stopped by the local GM dealer, this afternoon, and I'm due to drop it off next Tuesday, AM. Talked to their guy about these issues, as well as the old, on-going AC issue, talked about in these pages, earlier. So, is there any chance that I can resolve this DS door issue by the time I get with the dealer? Or, am I just looking at throwing money at it? I have the Helm manuals, but they're so involved for someone without a Tech II, that I can't make much headway. And, by the way, there were no codes set, when I took it in to Maaco, about 8 days ago.
Looking at the brake issue as being a safety thing, and hoping that the dealer can get the brakes and transmission talking to the control modules. That's top priority for starters. I've checked the DS 25 amp circuit breaker, and it's good, as is the DDM fuse in the left side of dash.I haven't gotten into the Center Instrument Panel fuse block.
How much chance is there that the DD control module is so sensitive that I buggered it up with my analogue VOM set on Rx1? I'm 99.9% sure that I didn't re-assemble it wrong. I've only gone far enough into it to know that I have 12 V going in on the large orange conductor to the DD (driver's door) control panel, though there was one other (smaller gauge) orange wire that had very low, or no, voltage going to it, with the ignition switch on in both cases,BTW.
Well, that's where I'm at. Any hope, or suggestions? Sorry for the long discourse, but I wanted to give as much info as I could.
Thanks for any and all, as always, guys and gals.
