2006 GMC Yukon XL Denali Q&A
2006 GMC Yukon XL Denali Question: Where is the thermostat located and is it difficult for the owner to replace one?
The heater was working fine up until last week. Then it started blowing cold air. I messed with the buttons a bit and the heat came on again mysteriously. I added some antifreeze also. Now we're back to cold air again. Could it be the thermostat? If so; where is the thermostat located and is it difficult for the owner to replace by oneself? - Cha
by what your saying it sounds like the climate control head is at fault. You do have temp gauge in that auto it should be reading in the middle. - Boston1
