Question about 2001 GMC Yukon XL
Lately my 2001 GMC Yukon XL does not seem to get any fresh air because all the windows fog up. Putting A/C on or putting the button on outside air and not recirc. air along with putting on the defrost does not help. Could something be blocking a duct or something and how can you clean it out? There was a bad smell when putting on defrost about a month or so ago. Thanks
If you can feel the air from the blower motor blowing up on the windshield it is probably one of two things. Either your heater core has a leak and the anti-freeze mist film is all over the windows or your heater control valve is not working.
Does the heater get hot or can you feel hot air on the windshield? If so your heater core is probably leaking and making steam inside your car.
