This has to be a faulty switch or varable speed resistor.
youre saying you have no control over fan. i see this when people bypass it as speed resistor is expensive so they wire it direct.

Heater not working in extreme cold weather because fan wont shut off. fan has been replace and the computer has been checked. nobody knows what is wrong


I'm making some assumptions, here.. I've been told I make too many assumptions... but, I'm assuming that you're talking about the engine cooling fan.. If I'm correct in this assumption, my guess is that you've not taken the vehicle to a good, reputable mechanic or repair shop. There are several reasons that an engine fan would not turn off, and each reason would have to come from a qualified mechanic. For example, there is a sending unit for the air conditioning system that might cause continuous running... or a sending unit in the air conditioning system that could cause the same thing. To complicate that issue, quite likely your air conditioning system purposely kicks on the engine fan any time you run your defroster. Also, your inside heater should function correctly, regardless of the engine fan running continuously. If I'm wrong on that score, then your engine has a thermostat problem "to boot"... which, by itself, could cause poor heating of the inside of the vehicle. NOW, backing up a little, if you so happen to be talking about the fan INSIDE the vehicle that is part of your heating OR air conditioning, we have a little different matter on our hands... First, some vehicles legitimately have a fan running on slow speed at ALL times.. for continuous air circulation purposes (sometimes, you can't actually hear this). Also, I might add that THIS fan running all the time should not be a problem for the heater to work properly.

2003 GMC Envoy main blower fan runs constantly


Does the fan stay on even with the ignition key off? Do you have automatic heating and air conditioning controls? Automatic controls have a light up blue screen in the middle of the temperature controls, and there will be a button that says "Auto". If you do have automatic controls, the likely culprit of your fan staying on constantly is what is called the blower control processor. The blower control processor is a small computer that replaces the blower resistor commonly found in cars. When the blower control processor fails, it usually "sticks" on. It's not a cheap part, but is easy enough to replace if you're handy with basic hand tools and comfortable unplugging electrical connectors under the glove compartment area.

Heat lack of


9 times out of 10 on this old of vehicle its the heater core. If your car temp gauge is working and the car is heating up fine and the blower works then it is most likely your heater core. Not sure how hard it is on that car. SOme times it just under the dash takes about 30 mins but some cars you have to pull the dash out. The part alone is cheap. I would try logging onto autozone.com put in your car find the part (heater core) then look at the how to change section of auto zone.

Goodluck.
