ea81turbo Posted December 30, 2020 Share Posted December 30, 2020 Fan works, heater works, but no AC or ac light. Any ideas? Quote Link to comment Share on other sites More sharing options...
DaveT Posted December 30, 2020 Share Posted December 30, 2020 I'm pretty sure the light is just switched by a switch in the button. Does the compressor turn? Does it run? Is there Freon in the system? Quote Link to comment Share on other sites More sharing options...

Is there Freon in the system? There is also a sensor on top of the AC pulley that is held by one 10 mm bolt (14 mm head) and one 6mm bolt (10 mm head). Make sure the sensor is as close to the pulley as possible. Good luck, Sam 1 Quote Link to comment Share on other sites More sharing options...

DaveT Posted December 31, 2020 Share Posted December 31, 2020 There is an electronics box in the system. What it does is monitor the sensor above the compressor pulley, and the pressure limit switches. There is also a thermostat switch in the evaporator. All of these are involved with allowing the compressor clutch ro be energized. Make sure it's getting 12V first. Probably be good to find the schematics also. 1 Quote Link to comment Share on other sites More sharing options...
