Just replace the ac clutch do to excessive play. Also checked for leaks. did an evacuate and recharge to be sure everything is right. I can not get the clutch to engage unless i put power to the plug manually. btw when i do this all my gauges say the high and low side pressures are fine. any ideas. I thought maybe the relay but I am not sure which one of the two it is on the pass fenderwell. thanks for any help.
