Silverado 06 A/C

[laneman]

I have an 06 Silverado that with A/C on high just started smelling like an electrical short 2 days ago.Intermitantly shuts off now for a while & will eventually come back on. Any suggestions?

The blower shuts off or it doesn't blow cold air, just hot air?

Blower shuts off on hi.Still runs on other speeds.

If you have a manual heater than the blower motor resistor assembly has a high speed fan relay built into it. I would probably bet that something has gone wrong with this assembly. It is located near the blower motor and will have about 5 or 6 wires going to it. With the switch in the hi speed position there should be power at the red, orange, and purple wires at the resistor.
