If youre changing it because it wont blow, try applying power to it first. It is on the passenger side under the dash if you take off the panel above the passenger feet. has a 2 wire plug in apply 12v to the motor, if it works replace the more common blower motor resistor which is located 3-5inches towards the front of the car from the fan itself. Also be sure to check your fuses.

2002 Pontiac air settings 1,2 and 5 don.t work on my A/C and Heater


Your blower motor resistor module has failed. You can replace it with a little effort. The cost is around $35 to $40.

The fan on my heater/ac stop working on settings 1-4 for awhile it worked on #5 but has now stopped altogether


The blower resistor has gone out but if blower is no longer working on speed 5 then either the blower motor is bad as well or the pigtail connector to the motor are bad. Check the plugs to the resistor and to the blower motor for insulation damage discolored or melted wiring.

What parts must be removed and in what order to enable replacement of the resistor in the blower fan,heater/ac??


remove the hush pannel from passanger side
disconnect the wiring connector for the blower motor (2 WIRE CONNECTOR)
remove the blower motor( not nessary but makes it easier)
now you can see the resistor disconnect the wiring connector
there is 2 bolts 5.5mm or SAE 7/32
remove the 2 bolts and remove the resistor
install the new resistor and reconnect the wiring connector
install the blower motor and reconnect the wire connector
install the hush pannel

AC/Heater on 2002 Grand AM SE1 will only work on one speed


chk. to see if you got a heater resister, it should be somewhere in the visinty of the blower motor 2 screws hold it in the heater box and it will have 4 or 5 wires in a plug going to it. samething happend with my truck and thats what it was. i also found out sometimes that plug with the wires to the resister burn, if thats the case you will have to chg. that too.
