ac pressure switch test.
Hi all, the compressor is not engaging on my 2006 mazda 3 2.0. Shop told me pressure switch is bad. want to make sure before i buy one and do it myself. I believe it is in the back left corner of the engine bay on the ac line. Does anyone know which of the four wires going into the pressure switch I need to jumper to test the compressor?
