E36 Heater Control Unit / Aircon Issue

Recommended Posts

Hi all.

Two questions here, I'm fairly sure the issues will be related:

1. So a few weeks ago my air conditioner became stuck on without my knowing and I couldn't turn it off, started making a weird noise, so I pulled the relay. Didn't really use or need it anyway. I have tried swapping relay with one I know works, made no difference. What is the likely cause of this? Do I need a new compressor?

2. The digital control unit is intermittent. It flicks on and off occasionally, and is on only about 5% of the time. When it is off (the little green vent selector lights are on mostly) sometimes it blows hot air - annoying! Is this the capacitor overheating or a faulty connection?

Comments/thoughts/solutions?

Thanks
