Question about Cars & Trucks
I turn the heat or AC on and the fan blows at low speed. the heat or cool that comes out is as it should be just not enough fan to distribute everything.
Sounds like the Blower Motor Resistor. The range from 10 to 75 dollars depending on what kind of vehicle. Pretty easy to change.

that seems to be the problem. If the fan does not turn on when the a/c is turned on it could be a fuse, relay, control box, or just a bad fan. Try connecting the fan directly to see if it works. Does this car have 2 fans? normally all the small cars have 2 fans one for the engine cooling and one to assist the first when the a/c is turned on. Without the fan pulling air through the a/c condensor the had pressure goes up high enough to shut off the a/c compressor. It also causes some cars to run warmer than usual when stopped. Check the a/c condensor for blockage also which doesn't have anything to do with your fan not working.

That is the blower resistor. 4 is wide open, so, no resistance. I had 4 of them put into my truck. The wires were burnt and shorted the others until the problem was found. Check the plug if you do this yourself.

You have a problem with the resistors on your blower motor. 95% of AC/Heater blower motors are located under the glove box in the passanger foot well. When you remove the motor you should see a resistor plate. Resistors are not servicable and will need to be replaced. This is a relatively cheap part, that you can replace yourself if your handy, if not take it to your local tech.
