A/C switch doesn't seem to work I replaced the switch with a used one same problem. The compressor turns on but no fan

So yesterday the A/C was working fine then I shut the truck off and started it back up a little later and the A/c wouldn't work. Then this morning I started the truck and the A/C worked fine for a while then shut off. I replaced the control switch with a used one. The A/C worked fine for a while then stopped. Do you think it could be a short in the wiring?

maybe.check the resistor for being burnt.then check the blower motor connections,maybe not plugged all the way in. if it's doing the same thing with a different switch,probably not the switch.check all connections for corrosion also.

Thank you for your help I will try your suggestions.

I checked the blower motor resistor it was fine. Replaced the Blower Motor. That fixed the problem. Thanks again for the help.
