A/C Controls

[SilveradoWV]

Does the truck have some kind of sensor that turns the A/C on when the A/C button isnt pushed??? My A/C comes on when I just have the button pushed for the resurculation on inside air. The A/C biutton isnt even lit up but the compressor is running!

There is a microprocessor in the control head that turns on the compressor.  The A/C button does not light.  It is part of the program in the microprocessor.  When put on the defrost, the recirc door opens and the compressor kicks in too.
