Ωhm Posted August 27, 2019 Share Posted August 27, 2019 A/C Clutch Relay engages the A/C Compressor, this relay is controlled by the ECU with information from HVAC Controller. B+ from C236_A (connector for circle in picture) , thru A/C Low Pressure Switch, thru A/C Clutch Relay (87 (4)) to A/C compressor. Link to comment Share on other sites More sharing options...
cruiser54 Posted August 29, 2019 Share Posted August 29, 2019 So, I think A (light green with tracer) might be what you're looking for. Link to comment Share on other sites More sharing options...

Vakarian Posted August 29, 2019 Share Posted August 29, 2019 Not to steal the thread but would this cause nothing on the AC system to turn on? The only air the comes through for me is when the fan speed is off and on vent. The fan doesn't turn on at all and all the vacuum lines are all attached.
