Just installed new compressor, dryer, o-rings etc, recharged the system and it blows ICE cold. Only problem is you can not switch off the compressor with the A/C switch.

Any advice on where to start?

Thanks!!!!!!!!!!
 
:meh:Sorry I dont have an answer but I am having AC problems. Did you do a conversion or just revamp your R12 system? I'm trying to decide what to do. I just dropped $250 worth of R12 into a leaky compressor and now I'm so pissed I can't see straight. How hard was the work you just did. I'm no master mechanic but I do a decent job of what I can. Thanks for any insight. Sorry I'm no help.
 
Pull the blue switch try to turn it off there. Mike

Thanks.

I will pull it apart and see if it is in that switch. The light goes out, just doesn't change the compressor.

Any other relays that could/would cause this?

Does the Comp clutch disengage when you disconnect the wire going to compressor?

I bought a new compressor, a little less than $250 and did the conversion.
 
Clutch will let go if its got no electricity. If not, its bad. MIke
 
It does disengage when it is unplugged.
 
Get a switch. Mike
If the blue AC light goes on and off, I think the switch is working correctly. Power to the blue light and to the pressure switch/amplifier/VSV/clutch comes from the same side of the AC switch.
