Heater Wonít Shut Off Completely

Itís always done it a little, but itís getting worse.

My vent air is 10į F warmer than the outside air. Anybody see this before?

It was 96į F today and I think it's going to get much hotter this summer.

In both of the Cobalt's I've owned, air does continue to flow through the vents even when the fan speed is set to 0. The temp of the air can be adjusted by turning the thermostat, but I don't know of a way to stop it without closing the vent covers.

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.
