I have a 02 Pontiac grand prix and the blower motor will only work on high. I have replaced the controls and the motor. Could it be the resistor?
i have an 03 grand prix and yes it was the blower motor resistor also check there is a fuse for fan low and fan high or something like that
Why does the heater on a 1998 Pontiac grand prix only work on high?
The blower motor resistor circuit board has gone bad. Replace the blower motor resistor. I did Still dont work Try the fuses...Had the same problem and it was a blown fuse.
On a 2001 Pontiac grand prix gt how do you know if the heater blower motor resistor is bad?
Blower wont work on all 5 speeds, usually the lower speeds tend to go first.
What causes heater not to work on a 1993 grand prix with a 3.1?
Does the blower work? If not the problem is likely the fuse or a failed blower motor. If it works but blows cold air you probably have a broken engine coolant thermostat. Have you checked your coolant level?
1994 Pontiac grand am blower motor does not work?
Check your fuse box for a blown fuse and also check your connections at the blower motor.
What if the blower motor resister isn't bad on a 2002 grand prix gt.?
if the resistor isn't bad then you should have all speeds, temperature, and levels for the vents working. if your not getting anything blowing threw the vents at all give the blower moter a couple taps and if that doesnt work then its 99% likely the blower motor is blown
Why would a 2001 Pontic Grand Prix GT air conditioning only work on the high setting?
I have a 2002 Grand Prix GT that does the same dang thing!!! With the heat and the air!! Hey Bill ==It could be the resistor pack which is on the evaporator case. Check it out. GoodluckJOE THE PROBLEM MIGHT BE AS SIMPLE AS A RELAY FOR THE BLOWER MOTOR. I had to deal with the same thing on my 2001 Grand Prix GT, just last week. I turned out to be the blower fan motor resistor pack, which is located under the passenger side dashboard, behind the blower fan. It was really a b!t@# to get to, and I had to remove the fan, but once you get to it, its and easy fix. I fyou still have a hard time locating the resistor pack, look for two wires (either red and black, or purple and black) running to the blower fan motor.
What makes heater quite blowing on a 2003 pontic grand prix?
could be a fuse, a relay, the blower motor or the blower resistor. It's easy to check the fuse, using the owners manual. I am not sure where the relay is, and it requires special tools or replacement with a known good relay to test. If the blower works on high and no other speed, then the resistor is bad. If fuse and relay are good, and blower does not work in any position, suspect the blower motor itself.

I had this problem with my 2002 Grand Prix where it would only work on high, and even then only worked sometimes. I had to have the whole unit replaced. It was around $400.
When the blower does not work on all speeds is it the blower motor?
usually the blower motor resistor pkg. located on or near the blower motor
What does a blower motor resistor do if it is bad?
blower motor won't work
