You’re missing in the top row:
Fuel pump
Fog lamp (think these hang below the front bumper, or it might refer to rear fog lights which are in the rear light cluster)
Seat belt warning (lol)
Rear window defogger
And in the bottom row:
Headlight flasher relay (low beam high beam switch)
Extra headlight relay (these are in the front bumper)
Fan relay (not strictly necessary)
Power windows is the one hanging on its own. |
THATS THE WINDOW RELAY???????????? bruh so it is just hanging out for funsies teasing me while I have my head up in the dash tryna look at the rats nest of wires.
We got the car in the shop for the next two weeks and today we tackled the battery ground and put in a more modern ground that isn't just exposed wire. I snagged a video of the upper tray for yall to stare at and see if there's anywhere I should be concerned with. https://drive.google.com/file/d/1mtRMqlZTL2uCs39H2hkQJG1QhNISNNqO/view?usp=sharing
I don't trust myself to not burn the car down playing with the electrical so I am holding off on messing with the relays and fuses until our friend who has a lot more electrical and car knowledge than I do is around

Definitely wants a serious clean and re-seal - but I've seen worse for sure.
Scrape off anything resembling rust, make sure there's no holes, and it looks like your seam sealer has dried up and separated - have had a good bit of that in my car. Cut/scrape out, possibly with a wire wheel (very messy but effective), degrease down to clean metal, paint over if bare - I recommend POR15 - and then apply new seam sealer to get rid of any cabin leaks etc (again, POR15 makes a VERY good product)...

I'll have to pick some up, I assumed the tray would need some love so it's good to know I'm not completely screwed. This might be a dumb question, but where does seam sealer belong in the tray? I'm assuming I'll find it around the corners where it joints and meets the walls after cleaning it out some more, but I just want to make sure I seal it all up properly if there's a common failure spot

The seam sealer you want where all the individual steel panels meet... and you can even use it to close over small rust holes, as long as all rotting/rusty metal is removed to bare clean steel and then painted...

Thanks Vaughan!!! I'll report back after clean up/arts and crafts with the battery tray

So uh what do I do if there's fiberglass in here overlaid the old metal in some parts??????????????????????? I just cleaned out all of the gunk to get ready to wire wheel and uhhhhhhhhhh I was not expecting fiberglass. I also found what looks like is supposed to be a drainage hole? I think? https://drive.google.com/file/d/15RoLsXae4NojmFt6Z9-m8Wl_PUDP8coO/view?usp=sharing https://drive.google.com/file/d/1ZeakECYXNGQXlocqIeyBTnIt3h80O61C/view?usp=sharing

Yeah, so the problem with fiberglass is that water could get underneath it and wick in, then start corroding the metal underneath.
But it's easier than grinding out rust and welding it back up properly...
You could try sealing it around the edges, but you won't know if there's damage underneath, and if there is any corrosion it would likely continue to get worse.
Looking up from the inside might give a good sense; may have to remove the glovebox and maybe also drop the AC unit a little to get a good look, but if there's and damage all the way through, you'll be able to see it.
While this metal is all galvanized, the battery acid will cut through that no problem, unfortunately.
We had to fabricate an entirely new battery tray for my Turbo, it was very badly rotted out.
The drainage hole is actually at the front edge of the tray, poking through the firewall by the exhaust manifold - should be easy to see, there's a little pipe about 1" in diameter through the firewall...

yeah what's left of the drainage hole recreated by the fiberglass is what I found. It's looking like I'm going to have to rip out the battery tray and lay down some new metal. What all do we have to remove from the interior and the engine bay in order for us to weld in a new sheet safely and not melt anything and/or catch the car on fire?

Not too much in the engine bay; only real concern might be if there's any of the firewall insulation/noise damping blanket still present.
For the interior... the carpet, sound deadening, and AC unit... but could probably leave the heater core and box in place...

Alright, while I'm chewing over my options with the brakes, I'm bouncing back to this side quest.
Facebook marketplace is a dangerous place and I should not be trusted to go on there.
I have found a part out of a '81 931 and it had working electric windows. Therefore, I am claiming the relay, switches, and the plastic surrounds because my one is broken in half. From what I can tell from the PET and the army of posts on here I found, the PN for the relay should be 321 919 505 which was in the 924 and the 931 until 83. This relay also lives up near the center tunnel/HVAC on the 931s but on the 924s somewhere near the steering wheel. According to Raize, my dangly dude is the window switch so that doesn't help me with trying to direct this person as to where the relay lives because they also aren't totally sure. Does anyone have a picture of where it actually lives on both cars? The posts I've found have expired links for pics
The switches also seem to be the same PN and both cars windows operate off the relay and auxillary fuse 8. So in my mind this should be a swap out and if it still doesn't work it's either the motors in the windows or the stupid wiring nightmare.

Alrighty, I'm back with some good news and some bad news.
Good news: I've installed all new fuses and cleaned up the contacts (at a later date I'll rip everything out and recrimp because I need to figure out all the electrical chaos) and the driver window works. All of my switches are good after I played musical switch and the purchased switches are also good.
Bad news: Passenger window (aka the one I need to roll up) doesn't budge and I don't hear the motor engage like I do on the driver side. Clark's said the passenger switches are in series, so I'll have to go wire hunting and see if its been cut somewhere or disconnected. I don't want to rip the door card off if I don't have to, but I probably will have to to test the motor.
Even worse news: Upon starting to rebuild the battery tray (I decided to just rebuild it with fiberglass and started ripping out the old junk) we discovered the rain has been draining to the inside of the car. By some miracle from god my floor pan from what I can see from ripping up the corner of the carpet is intact, solid, and only has a bit of surface rust. We have to cut out the fiberglass I did not remove because it's like a half inch thick and see what's going on because from the remnants of the drain hole you can see into the passenger side.  The seats are also still one with the car and now we know why, but the passenger side seat needs to be evacuated so I can evaluate how screwed the floor pan really is with the carpet removed.
I have serious questions for whoever designed these things. I also need to know why there was cooler foam up against the firewall and a million and one layers of sound dampening and cardboard? plywood? something that is hard but also brittle and not metal and is trying to be one with the floor. But seriously, is like three inches of white cooler foam at the firewall from factory or did the rednecking go that far?
I also found wires underneath the carpet, but I'm not totally sure if these are factory or if this is more redneck ingenuity. https://drive.google.com/file/d/1AcYs7iOQ5pSeEWojhKeIFKEDw2qjllCN/view?usp=sharing
