I'm assuming that the fan only blows on the high setting. This is due to a resistor that has failed and needs to be replaced. I had this problem on my '98 GP where setting 1 stopped working, then 2 and three in sequence. The tech explained that a resistor had blown. After replacing the failed parts, they began to burn out again in the same sequence after a few years. The car was wrecked before I had it repaired again.

Why does your 1999 Yukon heat only work on high?
If you are referring to the blower motor only working on the high speed setting, then the problem is the blower motor Resistor Pack is defective. Replace it. It can be the blower motor speed control switch but not likely.
If my cab heat and ac fan only works on high setting is it bad relays resistors or motor?
AnswerI think it is the switch or the wires. Actually it would most likely be the resistor motor is shot, if the blower motor only blow on high there is no resistance thus it will only work on high.

Why would a 2001 Pontiac Grand Prix GT heat work on a high setting It was on the 3rd setting and now I have to put it on the 4th setting in order for it to work?
fan selector switches are usually riostats it will not make good contact on other settings and therefor only works on 1 setting change switch byou can pull it and check with meter Replace the blower resistor. It is under the glove box, behind the blower motor. My 2001 Grand Prix did the same thing. It used to work nicely on setting 2, and over time had to increase to setting 3, 4 and so on to get the same amount of heat. Eventually was getting no heat at all. Brought it to the garage and they replaced the blower mechanism and all was well.
What would cause the air conditioning to work only in the high setting in your 1999 buick century?
Change your heat control sensor it mount on your heater motor on most models, it reduces the amount of voltage to the fan motor.
Why does the heat blower only work on low and medium but not on high?
the blower resistor controls the fan speeds
Why does heat fan on Toyota Solara only work on high?
You most likely have a bad blower motor resister.......
Why would your heater in a 1997 Hyundai elantra only work on high but does not blow out no air on settings 1 2 and 3?
Many cars have a blower motor resistor which regulates the lower speeds. When this burns out the only setting that will work is the high setting. I suggest you check with your dealer about getting this part and its location on your car. I hope this helps you. Mark

Why does your heat only work when your car is moving?
The heat will also work when the car is turned on, but not moving. It uses heat from the engine.
