Hello i send a video my compressor working and air blowing cold. But here's the problem my ambient air temperature sensor was reading the outside air fine but once I starter driving its drop below 16 degrees and compressor shuts off and now the sensor going up and down and not consistent anymore. So I went to oreillys pick up a Dorman and install drive my car to read to the temp and still it remains the same reading its ice on dash but in illinois is 88 degrees plus I had a P0645 code so I have new relay on deck swap it out and still the dash reads ice and compressor not moving. No fuses blown or wire damage. Something is playing with my ambient air temperature sensor I hook up a scan tool my inside temperature under my driver wheel reads accurate but that ambient sensor was at 32 degrees when its hot over here. I don't understand but did this means my compressor clutch going bad because it want turn on when the ambient sensor reading 32 degrees. I dont get it. But when I drive the ambient air sensor bounce around when its new from the store I change so my ambient air sensor its killing me over here. Thinking compressor giving me signs cuz the wires all fine
