I had to replace a b.m resistor on my 05 Pont. Grand Prix and it was not that difficult and saved me a bunch of money. As fas as I can tell, and as in my case, if your blower motor is staying on high (even with the key out) then you have a bad resistor. The cost of mine for the 05 was $70. It was actually cheaper at the dealership and was in stock. It was really simple to replace. On the Grand Prix it was located under the glovebox. It's not very big and should have a wiring harness running into it and then from the resistor to the blower motor. There were two screws holding it in and just the one harness to re-attach. If you have anymore questions let me know. de2jmb@Yahoo.com
Recommend you check the blower motor resistor.
If you are referring to the blower motor resistor then it is inside mounted on the evaporator case.
If your wondering because you only get a 2 or 3 selection for blower instead of 5. and your replacing blower resistor, im told go behind glove box? never tried it. The blower motor is directly above the glove box. Directly in front of that is the resistor for your ac/heat.
faulty blower motor resistor
The blower motor resistor on a Mercedes 300e is located beneath the blower motor on the Mercedes 300e, if ever it needs replacing.
Replace the blower motor resistor.
There is only one blower motor resistor and it is located in the evaporator housing.
Blower Resistor is located near the passenger side floor. There is a black cover over the blower housing. Remove the cover and you should see it. You may need to pull the carpet back to get access to the resistor. Also be sure to have a
Replacing the 1997 Chevrolet suburban blower motor resistor can correct your air output issue. The air output issue could because by other things.
It is either the blower motor control switch or the blower motor resistor pack. More than likely it is the resistor pack. It must be replaced or just live with it until it fails completely.
where is resistor pack on 2010 impala lt 6 cylinder 3.5 motor
It's located up inside of the blower motor housing under the dashboard. I also have included a link to a video that will show you how to get to the resistor and also the tools that you will need for the job.
