It should be on the passenger side under the dash, Take the panel off above where your feet usually are and you should be able to see it.

SOURCE: locating heater blower motor resistor

the resistor is behind your glove box. open the box and push in the sides to release it and let it hang down...the resistor is right there. I didn't try to replace it, a friend did it, but the part was under $20.

SOURCE: Heater blower motor replacement -1997 Dodge Grand Caravan

Remove the cover plate on the passenger side of the heater box, 3-4 screws.
Unplug the motor assembly, remove 3-4 more screws that hold the motor in place and pull it down from its position. Get an aftermarket motor and installed it in the original housing with the original squirrel cage.
Installation is the reverse of removal.

SOURCE: 2001 Grand Prix: can't find the blower motor resistor on 2001 Grand...

Under the passenger side of the dashboard is a carpeted cover you'll need to remove. Once that's out of the way you'll see the blower motor on the RH side and just to the left of it right next to the frontwall is the blower motor resistor held in by two screws.
Here's a picture of the old design (right) versus the new design (left).

SOURCE: where is blower motor resister located on 1997

I was just reading an article by Lynn Rademacher on EHow. This woman doesn't know the first thing about this unit. The blower motor resistor on a 1997 Pontiac Grand Prix is more or less a module which contains resistors (yes plural meaning more than one) to regulate the speed of the blower motor.
Depending on the speed settings in your car controlling the blower motor anywhere from 3 to 5 speeds are possible. On most Pontiac Grand Prixs (and I've owned a 1990, 2 1998's a 1996 and a 1997 and a couple of Oldsmobiles which work the same way) there are probably 5 settings. Each setting has a resistor regulating the speed of the motor except for the high setting which does not have a resistor associated with it. It's just full 12 volts to the motor. I've had a resistor module which was a printed circuit board and several that are an assembly of welded resistors. This type is much better as the printed circuit ones have a tendency to crack or in one case the resistor fell off due to possible over heating of the circuit. These were only soldered in place. Getting to the point of location; all these vehicles have the blower motor and resistor module located under the glove compartment on the passenger side of the vehicle. There is usually a grey felt covered panel made of fibrous material under the glove box that has to be removed in order to get to the blower motor and resistor module. First and foremost you have to be a contortionist to get to the screws holding the blower motor in (more than likely 3 screws. Use a 7/32 socket to remove) If you can reach and unplug the resistor module connector from the blower motor do that first. This is located at the back of the motor (GM designers really knew what they were doing here). The connector has a latch which is a pain in the you know what to undo. This is all done by feel as you cannot see what you are working on. If you have a little mirror so that you can see behind the motor may help. But once you put your hand back there forget the mirror. There is also a larger connector engaged to the resistor module. It's about an inch long and has several wires running to it. Disconnect that one first if you can. It is also "latched" so you have to relieve the latch before you can pull the connector out. If you were successful in disconnecting the connectors, remove the 3 screws holding the blower motor. It will drop down and may be a pain getting out as the area is quite cramped. There are also 3 screws (same socket size) holding the resistor module in. 2 on one side and 1 on the other. You only need to remove the one or ones in front that are easily accessible. The one or ones in the back only may need to be loosened or maybe not at all. The mounting positions for the module are slotted so the part can be removed by sliding it slightly forward and then down. Reverse the procedure for putting everything back together. Resistor module first. Replace the large connector there. Then the blower motor. The blower motor by the way will only align with the mounting holes one way so make sure you can see there alignment first before you put any screws back in. The rubber ring going around the perimeter of the motor housing should lock into the mounting bosses to ensure correct alignment. Also there is a short bent air hose which evidently cools the motor while it is running attached from the motor to the housing that the motor mounts to. Make sure this gets connected. Holding the motor in place while trying to get one screw in is also a pain in the ****. Replace the fiber cover (or not) with the 2 or 3 little push in plastic gizmos. Upon completing this task your sides and back will take a while to get back to normal. Good luck!!!

Sounds like the temperature blend door actuator may be bad or the vacuum hose to it is disconnected.

Poor Heater System Performance CAUTION
Check all fluid levels and adjust as needed, before operating vehicle for extended periods at idle.

  1. Start the engine.
  2. Idle the engine until the thermostat opens (upper radiator hose will be hot) Is the engine at normal operating temperature (approx. 200° F)? If yes, go to the next step. If no, go to step 16.
  3. Set the mode selector to FLOOR mode.
  4. Set the heater control selector to the warmest temperature setting.
  5. Set the blower speed the lowest setting.
  6. Carefully feel the inlet and outlet heater hoses at the heater core. Is the inlet heater hose significantly hotter than the outlet heater hose? If yes, go to step 14. If no, go to the next step.
  7. Set the mode selector to PANEL mode.
  8. Select the maximum blower speed.
  9. Select the warmest temperature setting.
  10. Place a thermometer into the center I/P PANEL air outlet and affix a second thermometer to the heater core outlet heater hose.
  11. Record the temperature at the center I/P PANEL air outlet and at the heater core outlet heater hose. Are the two temperature readings about equal? If yes, go to the next step. If no, go to step 13.
  12. Inspect and repair the cowl, cowl area, recirculation door, and the HVAC evaporator/heater core case for cold air leaks. Repair any problems found, go to step 17.
  13. Inspect the temperature door operation. Repair any problems found, go to step 17.
  14. Turn OFF the engine. Back-flush the heater core. Start the engine. Select the FLOOR mode and the lowest blower speed. Select the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Is the inlet heater hose feel significantly hotter than the outlet heater hose? If yes, go to the next step. If no, go to step 17.
  15. Replace the heater core. When the repair is completed, go to step 17.
  16. Check for low engine temperature problems, Repair or replace as needed, go to step 17.
  17. Operate the system in order to verify the repair. If the system operates properly, the repair is complete. If the heater still does not work properly, repeat the entire procedure.

The heater and a/c in my 2003 grand prix will on


Your blower motor resistor is the problem.
The blower motor resistor is located near the blower motor on the passenger side in the heater case. The resistor is held in by two screws and has one electrical connector that plugs into it. Purchase the resistor and you will know exactly what you are replacing. Good luck

2005 Grand Prix GT


There is a heater resistor module, it is located on the passenger side under the dash by the blower motor. It is a bit tricky to get to but isnt to hard to replace. I just dealt with this issue in May. The unit cost me about 86 dollars from the dealer. But be careful becuase normally the resistor goes due to a short in another component in the syste, so this may not be the complete fix for you. My main culprit ended up being the blower motor.

Good Luck
