Mazda Repair: 94 mazda 626 a/c, mazda 626, luck chris

Question
my 626 a/c compressor fails to engage,, all system pressures are good, fans come on but
the compressor will not engage???

Answer
Hi WEbber thanks for asking,
I will need you or someone to check is there is power going to the clutch on the compressor while running, If there is power going to it then the compressor will have to be replace, if not then there is a possible open or short in the wire, or a faulty relay, I dont see it being the pressure swich because as you said the fans are kicking in, If it only one fan on then I would look at repling the switch.
Good Luck
