AC compressor not receiving signal

Post by mc4457 »

Hi Guys. Does anyone know if there is a relay or fuse between the AC switch on the dash and the compressor? I used my multimeter in the jacks at the comp and they didn't seem to be getting any elect when I turned the switch and obviously the comp doesn't spin. The other thing that is weird is the module B 1 position doesn't light up with any code. The other B module locations light up with the 111 code. It seems there is a short between the switch and the compressor. Thanks.
