Bargain 87 325i

[Brinkley]

Hello all, you may remember me from such epic fail threads as the rotary swap. i'm back ( just with an e30, no plans to pick back up w/ rotary ) with a purchase that was just too good to pass up, a 325i for 400.
It's got a few issues:
Didn't run when I got it, replaced main relay, runs fine now.
Overheating: Expansion tank return line was unhooked I noticed when she came up to temp lol. Went to perform bleed and discovered next problem:
HVAC fan / Dash computer : Don't work at all.
Rear windows don't work, fronts do.

Any suggestions? Thanks in advance!


Oh here's the pics:

I would say...

Swap a rotary in there and call it good.

400 bucks? what a rip.

i got my '90 325is for free.

i say remove the rear seats and swap in the engine from the mr2.

slam it do the ground, then swap in a prius powertrain, and be letting sparks fly in the carpool lane

Back to the rotary... What happend?

I have a 12a paperweight under my workbench.

lol, i realized that I was way out of my league on that swap. I just want to enjoy the e30.
But seriously, any ideas on the hvac thing? I saw someone mention an "unloader relay" while searching for answers but couldn't get anything specific.

The Blower motor is under a panel accessible from the center top of the firewall. does it work if you turn it on 4? Change the switches for the rear windows, and make sure they aren't locked out.

Yea I saw a few threads that said it would only work on speed 4, but mine doesn't work at all at any speed, so i figured it was a fuse, checked and it's good, that's why i kinda figure it isn't that resistor pack in there
