Hit a coyote in my 2005 Volvo V70 2.4 which took out the A/C condenser. The A/C worked beautifully before the incident. I replaced the condenser along with a new accumulator/drier. I had the system evacuated and charged at a dealer. Now the compressor will not engage with the A/C on so I get nothing but warm air. I jumped the relay and got the compressor to engage that way, but it will not engage on its own.

Is there a low pressure switch somewhere that may be the culprit? I looked all over the lines and can not seem to find one... Could the relay be the issue? Any other fuses or sensors/switches I can check?

Thanks

 

Not sure about the switch but it may not be turning on because the pressure is too low due to a leak. Do you have access to a manifold gauge so that you can check the operating pressures?
