Question
I have a 2002 GMC Envoy and my air-conditioning worked perfectly all summer. Now that it is getting cold outside, I switched the mode to the floor and upped the temperature
but I only get heated air coming out of the dash vents and/or the defrost but none on the floor. What kind of an
expensive repair might I be looking at? Please & thanks.
Could be a stepper motor ,the climate control unit,or the vents may be stuck with dust.Either way its a expensive fix as most of the dash has to be removed so i would live with it.It depends who is fixing it,dealer is going to charge you a fortune and if you get a person who doesnt know what hes doing then it may not be much cheaper.So,personally if it blows heat,leave it alone.Have a look yourself under the floor where the heat comes out and turn the vents from upper to lower a few times and see what happens.Rough guess as to $ would be from $400.......or there abouts.

| Comment | Thank you very much for your quick response. Sounds like I'll just live with having the hot air blow in my face and adjust to having cold feet or buy some warm boots. | ||
