I had a 2001 doing the same thing. Mine was a poor connection at the blower motor resistor assembly. This is located on the passenger side floorboard under the dash. It is a flat connector with five or six wires going to it. Turn your ignition key on, turn your heater on high and wiggle the connector, there is a good chance that it will start working. If it does you'll need to disconnect the connector and clean the terminals with a small pocket screwdriver, small pick or equivalent tool. Good luck.

Sounds like you have the same problem as I had. The blower motor is located in the far right upper corner under your glove box. near the firewall on the passenger side. the relay is located in the outer housing and mine was shorting out. Also my thermostat controls on the dash were going. Finally It just quit. Had to replace both parts. Works great now. Also sometimes no heat at all, or just air conditioning.

My heater worked a little bit today when I had the thermostat changed but notice the fan wasn't working and that's why it did not heat the cabin. Now I notice the air compressor is coming on while the

well the ac compressor will come on if you have it in defrost mode,if heater is blowing cold ,after you just had thermostat replace ,you could possibly have air in if your heater motor is not working which is called the blower motor under dash it could be the resistor that controls it also these rigs have been known for wire harness problems at heater control unit and the blower motor connector.good luck,mike

Rear heating problem

Hi Jeff. I had the same problem, along with others on my 03 Denali. Along with not blowing hot air from the rear heating system, I had hot air blowing out of the passenger side and cold air out of the drivers' side vents. My battery would go low and had the same smell. I took my Denali in to the dealer and they found it was a bad Fan Control Module. They replace it and everything worked well after. It cost me $293 for parts and labor. Hope this helps.

The fan in front of my radiator broke apart recently on my 2001 Blazer. I had to replace the radiator, fan, timing belt and water pump. Then it ran hot; between 200 and 250, it always smells hot and it...

Heat will not hurt the plugs, but it may have hurt something else. Look around for melting ignition wires or anything else too close to the exhaust. Rough idle will usually set the engine light--is it on? If not, check to see if maybe the egr valve is stuck open.

The truck is running hot but not always overheating and the a/c causes it to heat up faster. I just changed the thermostat. I would like to use the a/c. there is also no leaks.

When truck running hot, with AC off, try throwing the heater on high heat, high fan & see if gauge starts to go down at all. Ya it might get a little hot inside but good way to test if rad is problem or not. If temperature goes down noticeably, I'd be thinking about a new rad.

Heat gauge shows hot , have to add antifreeze although no leak

Very common fault is head gaskets.  causing coolant consumption and bubbles in radiator.  Run vehicle, have a friend accelerate once or twice hard, while you smell exhaust for sweet smell of burning coolant.
