Question about 2002 Chevrolet Prizm

1 Answer

Heater/AC fan Today, my AC/Heater fan on my 2002 Prism stopped running in the first three speeds and now only runs in the highest. Does this indicate fan replacement or could there be another electrical problem causing this

Blower motor resistor is the most probable cause of this i would go to the dealer after market part for this will leave you upset and you will just wind up at the dealer anyway

It may be the bearings in the motor are dry or out. You coulod pull the motor and fan assembly out and check its operation while it is out of the heater case. Look for anything inside the heater cavity where the motor sits for any problem hindering motor operation.

if the fan runs on only one speed, its the blower motor relay.

the clock shouldn't be on the same circuit as the fan, I dunno on that one, but there is a relay for the fan.

The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.

2002 pont. grand prix-Heater/AC Only works on High


you need a new speed control resistor... this is something you will have to get from the dealer, but you should be able to replace it yourself - it is under the dash on the passenger side mounted near the bottom of the fan motor.. you will remove a couple of screws, and it will come out of the black casing it is mounted inside.

Heater (and a/c) blower motor runs only at the two highest speeds


I had the same exact symptom (02 Prizm LSI)..Order yourself a Blower Motor Resistor (I clicked on it---scroll up on this same screen that you are reading--- AC Delco part, $25.79). When the part arrives, look at it, and then look behind and to the left of your glove box door, YOU WILL SEE IT RIGHT AWAY. 2 screws, takes about 10 minutes to change. Its been nice to get all 4 speeds back! Good luck.
