Ok how is everyone doing new to this site. I've got a question about my a/c when its cool outside example early morning a/c clutch works fine a/c great but after work when go to turn on a/c hot air clutch not engaging until i drive for about 40 minutes or so changed relays both for clutch and fan checked levels reading perfect i work at Goodyear and all the guys there are stumped as i'am also, been told the control unit on the inside is going bad also been told the ecu is going bad checked plugin that runs of a/c harness to plug on compresser no signal after work today that is anyone know what it is i need to change to fix this to hot for no a/c anyone thoughts and suggestion will be appericated thanks upfront.

 

okay, like a crank sensor that goes out when the engine is hot or when you shut it off after its been hot, and then will not restart, sounds like the coil in the compressors clutch is going to open circuit when its hot, and once it cools, its fine. double check how you measured the clutch power signal, usually its fine, but i have heard of the pushbuttions going out.
