heater, window woes....tied together

[Chris E30 Cab]

Since i bought this car a month ago the heater/ac blower & power windows work sometimes and other times (same times) they don't work.

I'd imagine something is shorting out somewhere but any idea where?

At times when everything is working and the car transfers its weight forward, under braking, the blower & windows quit. It sometimes comes back on when I hit the throttle hard to jolt the car but many times it won't and it takes days before it decides to warm me up.

Anyhow, before I start pulling the consoles I thought maybe some of you folks might have some ideas on where to start.

Thanks,
Chris

loose ground probably. look at wiring diagrams to see if they both share a common ground.

Your unloader relay circuit is acting up. Do a starter recently?

Check the starter connections. I had the same problem and found a loose connection on the starter. Good luck!
