My A/C seems to have a mind of its own. I think when it's hotter the switch (green LED) doesn't turn on, therefore the A/C doesn't work.

What should I be looking for?

TIA.

 

1. take the control unit out and check for cracks in the circuit board and or loose solder joints you can repair the cracks with small peices of wire and resolder the bad joints.


2. check the switch contacts for carbon buildup and clean as needed. tuner cleaner works very well on that....
