Sweating my azz off. AC problem

[devon_344]

Ac has been working fine till this morning got in truck and noticed no cold air.
No change in temp from ac on or off. But function will swap fine between defrost, vent or feet. Checked fuse and relays all good. Clutch on compressor moves freely but compressor is not engaging. Changed but pressure sensor switches " one on dryer and the one next to passenger battery. Still nuttin
Gonna check if compressor is getting power and freon levels Tom.
Any other ideas or pointers would be appreciated

If its not coming on at all but you have pressure in the system... maybe check compressor relay. My sisters toyota car did that. Relays are pretty simple to check.

You can test the switches for power and continuity. If the charge is good and switches are closed you should have continuity. Also using a dvom check to see if you have 12v going to each switch, no power it's possibly the relay or bad wires
