Thanks for the reply, but thatís not my issue. My problem is with the temperature. If itís 90 F outside, my vent will be discharging 100 F air, once the engine warms up.
Thatís OK in the six weeks we call winter, but the rest of the year it means my air conditioner is blowing 10 degrees too hot.
I had this happen in a Dodge and it was a leaky heater diverter valve. I donít know how the heat is controlled in the Chevy. I was hoping somebody had experience with this issue or knew how it worked and could pick a likely suspect.
