Mine does the same thing. It heats really good but, the vents open. I noticed in the last few years some black foam has been coming out of the vents. I figure the vent door had foam on it to help seal and now it's gone.

> My 97 sport (no air) seems to be leaking cold air into the heater system, if I turn OFF the heat control and fan, I still get cold air blowing out when I drive.
>
> My heat sux big time even when the engine is up to temp. 195 therm. If it's cold it takes forever to even clear my windows!
>
> I'm thinking the vent air is sticking open, though opening & closing the heat from hot to cold alot hasn't helped so far.
