Report: AC Blower Inop Due to Failed Resistor
Pontiac Grand Am Problem
Model Years Affected: 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005
Average Mileage: 102,395 mi (50,000 mi - 189,000 mi)
The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

The 5th speed on the fan doesn't work. I tried replacing the resistor, fuse relay and switch. Still not fixed.

I have this problem too.. The fan works on every speed except 3. What exactly is the way to fix this?

check all associated fuses and relays first!
my problem -blower motor did not work at all - replaced blower motor and plug(was corroded). blower then only worked on high(5). replaced heater resistor. checked resistance of resistor block and found it open. you can also check the fan speed switch by taking voltage readings at the resistor block plug to verify function.Flag ThisLike0 -

Have not repaired yet. Received quote of $200 for repair. Have learned that if only #5 works, it may only be the fuse. If #4 and #5 work, it's the resistor. Had repaired at same time heater core was replaced.

Fan would not operate on speeds 2 and 3. Replaced the blower resistor, which solved the problem.
