Q: My A/C clutch relay is not receiving a signal from the computer to engage the clutch.

asked by on February 21, 2018

The A/C clutch relay does not receive a signal from the computer to be able to engage the clutch. There is no pressure in the system, and I am not able to add anymore due to the compressor not spinning. I've replaced the pressure switch on the top of the dehydrator just in case this was sending a high pressure signal to the computer. When I jumper out the relay with the car off, I hear an audible click from the A/C clutch. I've swapped out the relay as well just to be sure. Also, the fuse for the system is good as well. Could this all be caused from a bad compressor not allowing the system to pressurize in the first place?

My vehicle is a 2011 Ford Escape 2.4L. It has an automatic transmission w/110,000 miles.
