#28 of 135 Too much heat! by focker1993
Jul 21, 2007 (12:50 pm)
I have a 1999 Chevy Blazer with the climate control. The problem is with my heat, it never stops. It constantly blows heat out of the vents. I can still change the direction ( defrost, floor, vents) and the speed of the blower, but cannot shut it off. The AC will not come on, the light comes on, but never any cold air, which I am thinking that it has something to do with this. I am looking for any suggestions please. It is hot outside and is unbearable sometimes to drive. Thank you very much
Any help to share a solution to this posting? Thank you so much

This problem is caused by an Electrically Operated Temp/Blend door that is controlled by the Tempature dial on LT models with "Auto Climate Control". (If yours has a temp control dial with numbers from 65 to 85) Anyway this door is controlled by an electric motor that opens and closes the door to vary the temperature. This motor Is called the Heater & A/C Blend Door Actuator. Its Part Number is (Dorman 604-106) This motor can be replaced by dropping down the Glove Box, and reaching through. Its right on top of the heater box. The motor is expensive - around $100 - $120. That should fix your problem.

#144 of 154 Heater fan does not work all the time
Dec 11, 2011 (10:43 am)
I have a 2000 Blazer. The fan may or may not run. When it does run, the air temp is ok and heats the vehical and /or defrost the windsheild just fine. The controls check out ok. I think it is the vacuum system but I have no idea where to start, Any ideas?

I am working through some issues with my '99 Blazer. One thing I do know is the fan won't come on at all until there is hot water (anti-freeze) coming through the heater core. This is a built in function to prevent the system from pumping cold air into the cabin. You say that when it does turn on it works just fine. Perhaps that is the situation you are experiencing. Start your truck and let the engine come up to heat and see if your fan turns on.
