I have jumped straight to the compressor and it works fine. I swapped the relays but that did not help. I also bought a used heat/ac control located by the radio and swapped that but it still does not work. Any suggestions?
Thanks.

Have you checked the R-134a for proper charge? if it's too low the compressor won't come on, low pressure switch is there to protect against running a dry system..

The first thing we did was try to add r-134 but it was full. If it was low would the compressor come on when you jump straight to the compressor?
