Hello Fellow Volvo Enthusiasts!

Here is my HOT TOPIC.

My ac quit coming on a few days ago. Black Beauty needs her ac when its over 90 and humid!!!!

I took her to a tech I trust and he brought the 134a up to snuff, less than 1 pound lost over 14 years. Shorted the pressure switch and still the compressor wouldn't run. He shorted it at the compressor and it and the clutch work fine. (COLD ac!)

So we figure it's the relay and I'll go home and fix it. But I can't find it! And, all my manual has on ac is just a bunch of stuff about huge fines for venting refrigerant. DUH! All I want to do is fix the electrical.

So, Anyone know where the relay that turns on the compressor is?

Thank you tons!

 

Is it a manual control with vaccum lines?
