Air conditioner controls now working properly
The air flow only works when I turn to knob to defrost or high. Only the heat works and no AC, even tho I tried a recharge.
I’m thinking something is wrong with the electronics. Any help

From the posting:
Servo. Located behind the console RH cheek panel. The servo is the workhorse of the system that mechanically operates the vacuum valves, switches, flap linkages, etc. It makes a whirring noise when the dashboard controls are adjusted. When troubleshooting a fault turn the temp control knob and simply listen. Hearing the whir is a good sign. It means the system is fundamentally operational and is at least trying to comply with requests from the control panel. Lack of the whir sound means system is fundamentally inoperative. You can't go very far in diagnosing other problems unless you first hear the whir. The servo can be electrically divorced from the system for testing.
Fuses. This is the best place to start if you don't hear the servo whir and/or the blowers don't work. There are four fuses, two in the regular fuse panel and two semi-hidden inline fuses behind the console cheek panels. Behind the left cheek panel is a fuse on the amplifier ground wire. Behind the right cheek panel is a fuse clipped to the side of the heater case.
