May be the resistor pack. it is located under the dash on the passenger side. there is a connector that faces down near where your toes would go if you were sitting in the passenger seat. the resistor pack is held in place with 3 screws(i think) and drops down. fairly easy to replace.

Where is the heater fan resistor on a 2002 alero?

The Blower Motor Fan is situated inside a housing, which is behind the glove box. You need a simple 7 mm socket to take out the 5 or 6 bolts holding the glove box, disconnect the power connection to the glove compartment light, then you will see the cylinder-shaped housing for the blower motor right in front of you. The Resistor is located on top of the housing, which seems to be inaccessible from the "front" or passenger side. This part is where I am stuck... but at least I know roughly where it is!!!

The heater fan only works on speeds 4 and 5 on a 1999 alero where is the heat resistor and is it hard to change itHow do you test the old one to see if it is faulty?

Your lower resistor for the HVAC blowing unit is bad. You can buy this part at a carquest if you have one nearby for less than $20. I did some research on this since my 1999 alero had the same issue. I replaced it, and it did work for a little while (less than two weeks). However, it failed again, so i am stuck with my heater/ ac blower only working on High. I cannot locate the instructions I used to replace the resistor, but i can give you an idea, and you should be able to figure it out from there. Here are my simple steps: #1) First, you should buy the lower resistor for your HVAC unit from carquest or another parts store. is too pricey, but if you go to them or your local gm dealer, you can get the part as well... If you just explain the problem they should know what you need, but it is called the lower resistor for the HVAC blower unit. #2) after you have the part in hand, you will see that it has a wire connector (female end) and a credit card sized chip attached to it. #3) The blower motor is on the passengers side of the car, on the floorboard at the very front of the car attached to the firewall, you will have to lay on your stomach and look up to see the wire harness that attaches to this lower resistor. #4) the size of the nut is 7/32. A socket is probably they easist method on the FRONT nut, on the rear nut, you will probably have to use a 7/32 wrench, i bought mine at craftsman. Basically, locating the resisor is the easy part, i had extreme difficulty trying to get the resistor out, but i eventually did, and replaced it. Like i said before, mine crapped out again in less than a week, so i have not replaced it again, i figure that i can live with my blower working on only high, atleast it still works...
