Well my AC is till not working properly. It would start up almost everytime after the car is restarted, then would cut out at 1500-2000 rpm. I changed the ETR sensor twice. After the car slow to idle, AC sometime would come back and would cut out again at increase engine rpm.

Guage showed 30 psi low, and 250 psi high side at 2k rpm when AC is working or when jumping pin 5 and pin 7. Static pressure on high side is 130 psi with the engine turn off. The pressure switch is closed by multimeter testing. Bypassing it doesn't help. So does bypassing ETR either (I bought it here at Fastlane).


Is there other switches/relay that need to be check? Or is this a bad Klima? OVP? Throttle microcircuit?

Help, it is getting hot here in Texas.
