SOURCE: 2002 Chevy Impala Blower resistor location

It is on the passenger side, you have to remove the black plastic kick plate, below the glove box, to expose it (held in place with 2 latches and 1 push pin). The resistor is in front of the blower motor ( sandwiched between the motor housing and the firewall) it is tricky to get to, i think when i changed mine i didnt replace all the screws as they were difficult to remove and even harder to replace. Good Luck, Mike

SOURCE: I need to replace a chevy equinox blower motor and

I assume you already tried to buy the part through GM Parts or a dealership but as far as helping out with the replacement I would suggest Alldatadiy.com. I subscribed to a 5-year subscription for the Chevy Equinox manual for $30 as apposed to several hundred for the actual shop book. It has helped me out a lot with my replacements.

Blower fan only runs in positions 1-3, not on 4; relay or resistor?


Remove blower motor resistor and check to see if it discolored or melted. if so then replace blower motor resistor, also blower motor speeds 1-4 go through resistor, 5 goes direct from switch to blower motor. check wire harness connector at resistor, it should have six wires five power wires that corralate with the five settings on switch, so in each switch setting one wire should have power. the sixth wire is the ground. also harness connector to resistor it may be melted, if so go to dealer with vin number and get new harness connector with resistor.
I hope this helped.

Low & Med speed on A/C and heater not working, only high. Were is the blower at.


This problem is related to faulty blower motor resistor.The resistor is the part which controls the blower motor to work on required speeds.But if resistor fails then motor will work normally but will not work on selected speed like slow and medium .In this case replacing the resistor should help. Easy replacement, the resistor is located right behind the glove box. Drop the door on the glovebox and you can see it.Its fitted with screws,remove those screws and disconnect the resistor wiring harness from the main motor.Take care,before disconnecting wiring harness note down its connection and before removing resistor note down its placement.o while fitting new resistor you dont face any fitting and connection problem. -------------- This should help.Thank you.Helpmech.

HEAT DOSE NOT WORK WHERE IS BLOWER MOTOR LOCATED AND HOW DO I CHANGE IT


The blower motor is under the dash on the passenger side. You'll need to remove the plastic hush cover to get to it. These trucks are prone to this.
The blower motor fails because the resistor/ relay / wiring harness assembly overheats and can melt. Some of these have even caught fire. You're going to want to replace the blower motor resistor/relay and wiring harness assembly assembly too.
Check out all the wiring that goes into the resistor for heat damage. This assembly sits right next to the blower motor right above where the passengers feet would be. The resistor/relay is about the size of a pack of cigarettes and you'll see it right away. Make sure to disconnect the battery before working on any of this so you don't cause any more trouble while splicing in the new harness. I just did this on my 2006 Chevy truck and my blower motor was ok. I just had to replace the resistor/relay and splice in a new wiring harness. It cost $180.00 just for that stuff.

2005 Jeep Grand Cherokee. Htr/AC fan switch only functions @ highest speed. At lower speed settings I can hear doors opening and closing---but not air.


replace the blower motor resistor. It controls the fan speeds. It defaults to high speed only when it fails.

How to replace the blower motor resistor block: Caution: Stay clear of the blower motor and resistor block (Hot). Do not operate the blower motor with the resistor block removed. 1. Disconnect and isolate the battery negative cable.
2. Remove the glove box from the instrument panel.
3. Pull out the lock on the blower motor resistor wire harness connector to unlock the connector latch.
4. Depress the latch on the blower motor resistor wire harness connector and disconnect the connector from the resistor.
5. Remove the two screws that secure the blower motor resistor block to the HVAC housing.
6. Remove the resistor block from the HVAC housing. Installation:
1. Position the blower motor resistor block into the HVAC housing.
2. Install the two screws that secure the resistor block to the HVAC housing. Tighten the screws to 2.2 Nm (20 in. lbs.)
3. Connect the wire harness connector to the resistor block.
4. Push in the lock on the blower motor resistor wire harness connecgtor to lock the connector latch.
5. Install the glove box.
6. Reconnect the battery negative cable.
7. Have a nice day!

2000 chevy impala, air conditioning does not work


It sounds like the blower resistor needs to be replaced and the blower motor it self. Auto Zone will have the blower and resistor that you need to replace and will have the step by step instructions for you to get the job done with common tools and will take about 2 hours if your good with tools. Good luck and keep me posted. Setting 5 should have 12 volts running to the blower motor so check the wire harness for voltage readings at the blower motor harness clip, you may only just need a new blower motor.

Fan switch works on only one speed


  1. Disconnect and isolate the battery negative cable.
  2. From the passenger foot well area, remove the two hex screws used to secure the blower motor resistor.
  3. Unplug the front blower motor resistor from the wire harness connector.
  4. Pull the front blower motor resistor and its wire harness out of the plenum panel and through the cowl plenum access hole far enough to access the wire harness connector.
  5. Remove the front blower motor resistor from the cowl plenum.
INSTALLATION
  1. Plug the blower motor resistor into the wire harness connector.
  2. Install the blower motor resistor to the cowl plenum panel by feeding the resistor and wire harness back through the cowl plenum access hole.
  3. Install and tighten the two screws that secure the resistor to the HVAC unit Tighten the screws to 2.2 Nm (20 in. lbs.) .
  4. Connect the battery negative cable

I HAVE AN 06 H3 HUMMER the heater was blowing fine when I shut the car off ok, when I got back in and started it the heaters blower stopped. I have checked all fuses and relays and they are fine I even...


check the blower speed control, it most likely burned out, also jump battery power direct to the blower and see if it runs, if it does the speed control is defective, if it doesn't the blower motor is toast.

2006 Equinox fan blower quit working.


I have had the same problem happen, but here's likely what it is:

Either the resistor has blown, the wiriing harness has fried, or both, - or - it is the blower motor that needs to be replaced.

In any case, here's how to do it:

Check the resistor, its the easiest thing to do first. On the passenger side, under the dash -- WAY UNDER, by almost to the back, there is a wire that goes into the resistor.

The resistor controls the speed of the fan that blows.

There are 2 small screws holding the resistor in, unscrew them and remove the resistor - it is about 3 inches long and 2 inches wide and has ceramic covering. Remove the wiring harness and check both - if resistor is black anywhere, its probably bad. If the wiring harness is melted, and it probably will be, then it needs to be replaced.

Search online for a "Blower Motor Wiring Harness", you'll have instructions on how to cut the wires, splice the new harness and reconnect it. Also you'll need to replace the resistor.

One from the dealer will run you about $150.00, but I got one on parts.com for $26.00 + $10.00 shipping.

If you find that the wiring is fine, then its probably the blower motor.

Underneath the passengers side dash is a panel that covers the blower motor. Remove it, and youll see the blower motor. It looks like a hamstercage, circular with groves throughout its perimiter.

There are four screws holding it in, unscrew them, remove the wiring harness and take out the motor. Theres ways to test to see if it is the motor thats bad, but it requires a multimeter and some familiarity of where you're poking around. A new one will cost you some cash, but I picked up a used on on eBay for about $20.

Replace that, and it should come back on.

The problem though, is most likely the wiring, since GM has already put out a TSB with this wiring problem, and has since replaced the harness with a new model.
