2003 Chevy Malibu air conditioning settings

  • 6 CYL
  • 2WD
  • 70,000 MILES
When I turn the air on in the car only the number
4 and 5 positions on the switch blow out cool air.
on the # 1, 2, and 3 positions the air is cool, but the
blower part of it doesn't work. What gives?
thank you
Do you

Hi Cynthia. I had the exact same thing happen to my 2001 Malibu. It turned out to be the fan blower resistor. It is the same for your car as it was for mine. It is what regulates the different fan speeds. The dealer sells it for about 25 to 30 dollars. You can change it yourself if you are handy with a screwdriver. It is located in the cabin, underneath the glove box. On the bottom, there are a couple of panels you can remove with a screwdriver. Behind the panel, you will see what looks like a housing for the actual blower fan. Inserted into that, there is the resistor. It is a plastic rectangular shaped piece with a rubber seal around it (about 3in. By 2in), that has a wiring harness hooked up to it. When you remove the piece, you will see a circuit board on there, that is inserted directly into the blower housing. It is there because it cools off from the fan in there. You can buy the part before you look, so that you will know what to look for. Unplug the harness from it, replace it with the new resistor, insert it back into the housing and everything should be back to normal. If you inspect the old circuit board, you will probably notice that it is partially burned out. Do not try the new one without placing it back in its location first, because it gets extremely hot and can burn out. That is why it is located in that housing. Good luck. John
