Hey guys. My A/C just starting acting up. The system is charged full, no leaks. I found when stopped or when in park, the A/c compressor cycle on/off/on/off/on/off etc etc. I suspect the low/high pressure switch is shutting down the compressor due to excessive high pressure. While driving, however, it works fine. I noticed my Aux fans no longer come on. The fuse is not blown. The red switch on the receiver drier is working. When I short the red switch terminals, I can hear a click in the fuse box from a relay. I took the relay apart and it looked fine. Its not a Klima relay but more so a standard issue relay with two big relays inside it. I dont suspect the problem to be there, should I? I know the aux fans work because they were just on today when my temp guage ran hot.

I have no idea where to go from here? Can anyone help me?
