Hi,

I have a problem with my 1997 S70wherebyI am getting hot air whenI switch theA/C off. Sent the car to the local mechanic and he reset thecar by pulling out the Siemens control cards. Worked fine after I drove off but the next day, the A/C is stiill blowing hot air. I suspect the compressor is not kicking in. Could this be a electrical issue? I checked theA/C gas and it is okay with no leaks. Thanks for advising. Appreciate it.

 

Maybe relay or high or low pressure switch.

 

Thanks for the information. I will let my mechanic know and hope he is able to isolate the problem.
