This is my first winter with a 2000 Tahoe LS. The cab has a problem with steaming up the side and rear windows. It will steam up with only myself in the vehicle and the only way I can get it to clear is to drive around with the windows open. The heating system is basic, however it is all electronic. The dealer has said operating per spec 3 times and has told me not to bring it in for that problem again. I have protested.. Does anyone have a similar problem. I drive around looking at other tahoes on the road and they do not have steamed up windows. One thing I have noticed is that the windows clear up if I stop and get in and out of the vehicle frequently. They also stayed fairly clear when I have the service techs in the truck and we are switching heating modes. One thing that puzzles me are the two buttons for recirc/circ. When the system is set to cold and circ that air is cool but not as cold as outside air, when the system is set to cold and recirc it is cold like the outside air. With these AC assised defrost units will the AC run when the outside air temp is less than 32.. In defrost mode the circ/recirc is electronically forced to circ.
I am lost when it comes to servicing these new vehicles..
