This has been discussed many times here before, and I thought I would bring all of the information together in a "how-to." I have personally replaced this part with one purchased for $20-25 (Local Autostore, I.E. CarQuest, Autozone, Discount Auto) . The repair will take about 30 mins. to one hour to complete.
Problem: HVAC Blower motor only works on fan settings 3, 4 & 5.
Reason: Blower Motor Resistor is bad, and needs to be replaced.
Affected Model Years: 1997, 1998, 1999, 2000, 2001
You will need: 1/4" Socket set -or- a 3/8" set with a universal joint . 1/4 " prefered & universal with 5.5 or 6mm socket will work
1. Remove the plastic cover from the underside of the passenger dash under the Glove compartment, held in by four bolts. Note how the two air ducts on the left and top are connected, and how the other plastic cover piece is connected to the piece you are removing. This is helpful when you go to reinstall it.
1a. I found it helpful to remove the glove box. 7 easy screws and I had access to everything behind it and could see what I was doing.
2. Slide the Control Module to the right and pull it down carefully. Push it to the right being careful not to damage the wires.
2a. Control module on some cars is on the right and fit in a slot on the top of the module. This can remain where it is.
3. Remove the blower motor power cable located on the forward side of the blower near the firewall. Not necessary on some models.
4. Remove the jumper cable link to the blower motor resistor located on the resistor near the forward side of the blower.
5. Remove the blower motor held in place with three 7mm bolts. You may not need to do this, but it helps give you some room to work. It will also let see the blower motor resistor before proceeding. Not necessary on some models. Resistor is just ahead of the blower motor and removing the motor doesn't give you any more room.
6. Remove the two 5.5 mm bolts that hold the green (or blue) blower motor resistor (This will be the item you disconnect the cable from in step 4).
7. Install the new resistor using the two retained bolts. The improved part will be longer than the original, and will be black in color. Don't forget the soft gasket on the resistor.
8. Re-install the blower motor using the three retained bolts, if you removed it originally.
9. Re-connect the blower motor power, and the resistor jumper.
10. Test the blower fan settings prior to putting the dash back together.
11. Align and push the Control Module up into the slot and slide it back to the left.
11a. You will need to tie a piece of string around the hose like duct to guide it into the plastic cover on replacing, IF you have not removed the glove box.
12. Re-install the plastic cover using four retained bolts. This is where it helped to pay attention to the ducts and the other cover when removing.
*Note: on the 2.4L '98 Malibu, in step #1, there are only 3 bolts & 1 duct. Steps 2 & 5 are not necessary. I recommend buying the new resistor first, or looking at a new one so you know what you're looking for.
Replace shoes brake 2003 Chevy
just in back of glove box,down a little!!!
Blown fuse? Bad blower motor? see if you are getting power to it Bad blower motor resistor? Bad switch?
Replace the blower motor resistor.
how do i change my blower motor on my 2007 malibu
The blower resistor on a 1999 Chevy truck Z1500 is located behind the glove compartment. There is also a resistor on the firewall next to the blower motor itself.
Ain't no fixin it, you have to replace it with a new one.
if you have a 2003 Chevy Trail blazer and you need to replace the resistor for the rear blower, the one under the passenger side dash is the one that controls the front and rear blower.
The blower motor resistor pack is defective. Replace it.
if it is the same number on it!!
resistor card is under the glovebox. Remove glovebox door. Should be 2 screws I think holding resistor card in place.
The blower motor speed resistor is burned out. The resistor is usually found close to the blower motor. Auto parts stores carry that part and it is easy to replace.
how to replace actuator on a 2000 malibu
In a 1988 Chevy 2500, the blower motor resistor can be found on the passenger side. It usually is behind the glove box.
I you're talking about blower speeds 1 and 2 not working, then it's the resistor. Instructions on how to replace it are here: http://www.automotiveforums.com/vbulletin/showthread.php?t=175159
Most are behind the glove box; on many models you can drop the glove box door. I hope this helps you. Mark
HOW TO REPLACE A STARTER ON A 1998 CHEVY MALIBU
The blower resistor gets overheated and burns out usually because the blower motor is failing also.
First locate the resistor, it should be under the hood, on the firewall, passenger side, near the blower motor. Unplug the electrical connection, remove the small screws holding it in place then wiggle the resistor out.
Under the dash on the passenger side you will find the resistor. Remove the two screws and pull out the assembly. Unplug the old resistor and replace. Very simple repair.
The blower motor is under the glove compartment
Examine the back of the switch for loose or melted connections. Then examine the resistor for burned spots. In most cases a burned resistor is the result of a failing blower motor. So if a new resistor burns out in a short time, replace the motor also.
The blower is under the dash on passenger side. Remove lower panels (7mm), then blower cover. If your blower only works on 3,4 or 5 and does not blow on 1 or 2, you don't need a blower. You need a blower motor resistor. It is also under dash on pass side. Remove lower panel. Resistor is right up against the fire wall. Unplug it and remove 2 (5.5mm or 7/32) screws. They are kind of a pain to reach but I've done it many times.
In the truck!
Right next to the blower motor
