HI! So the only thing that shuts down the blower is removing the battery terminal? The fan motor relay may be corroded or faulty causing the motor to malfunction. You may just need to clean this if its corroded, but after cleaning is performed and still fails, I believe that the relay itself may need replacement. Hope this helps and have a good one!

My blow motor for inside the car sometimes comes on and off in my 2003 Chrysler sebring sedan when it wants to


Any motor that uses brushes, sometimes you can peck on it, it may start running, or you might hit a bump and the blower motor takes off. If so, that is a sign of bad brushes and the blower motor needs to be replaced.
Also when problem is ongoing, check the blower motor wiring connector, controls on, for voltage and ground, key on. If good voltage and ground with no blower action, suspect the blower motor.

Need to replace blower fan motor 2006 Chevy Malibu


2004 and up, the old blower motor must be cut out with a utility knife and the new one screws into the opening to the screw holes molded into the plastic housing. It is located under the passenger side dash, you may have a silencer / plastic cover there you have to remove to view it.
  • Remove the passenger's side lower silencer panel.
  • Remove the blower motor wire harness connector.
    Two diagrams show how it goes:

    Cut along the narrow groove where the arrows indicate. Do not cut too deep, only enough to remove motor, as the cup will be re used.

  • Install new motor assembly with three screws, usually provided with new unit. Tighten securely.
  • Atatch wire harness. Test unit. If functioning properly, replace silencer / cover.

    Heat or A/C does not work in my car?


    Either you have a blower motor FUSE that has gone bad "typically the problem" or you have a burned out blower motor. Usually the cause of a blown or burnt motor if not a Fuse, Is caused by the vented air from outside letting debris like sticks or leaves,acorns etc. enter the fan box. If ANY of the mentioned items get caught in the "blower box" then it will usually blow the fuse and or burn up the blower motor. Start in your fuse box and look for a burnt fuse and replace with same size fuse. If it blows the new fuse quickly then you have debris in "Blower box" that will have to be removed before adding yet another fuse. I have had the same problem and I found a bunch of leaves in my "Blower Box". I removed the leaves and replaced the burned out fuse. And I have had no more problems with the blower motor blowing air.

    Blower motor, cuts out after it runs for a while.


    Sounds like the motor speed control is going bad (resistors near the motor) or the motor itself is going bad, maybe bearing in it. Check the resistor control to see if it appears to be melted any.

    With the blower speed set to high and the key on tap the blower motor with the handle end of a large screw driver. If the blower starts to work than replace it.

    If it still won't work check for power on the purple wire (i think its purple) and make sure the ground is good. If those two check out fine replace the blower motor.

    If there is no power than you will need to check fuses and/or the blower motor resistor.

    Clicking noise coming from the heater blower motor


    if you car is equipped with cabin filter to filter the air entering the blower right, blower motor can be touching to sides of its housing since its bearing is broken.

    if no cabin filter, probebly you have leaves or small pieces of wood coming from trees. those are touching to the surface of blades of fan inside blower motor housing.

    Blower is not staying on. When I start the truck it will come on for 1 or 2 seconds then immediately cuts off. When it cuts off, I can turn the ignition off and then back on and its the same thing....


    The blower motor is most likely the problem.When it goes off,bump the blower motor with your hand to see if it starts back,if it does,the blower motor is bad.

    Where is the blower motor is on a 1996 jimmy


    The blower motor on you car is on the passenger side firewall inside the plastic case.Disconnect your battery before you do anything to your car.In order to get to it you will have to remove the Power Control Module from the top of the coolant recovery tank and then remove the recovery tank.Disconnect the connector to the blower motor and take the harness off the case.Now you want to cut the case along the molded lines in the cover as your guide.You also have 2 clips to take off between the top and bottom halves.Then take the screws and the cooling tube off and pull the blower out off the plastic case.There is going to be a pinch clip pinch it together and slide the fan off of the shaft and put it on the new one.Use the 3 mounting clips and align the cut edges very very carefully make a clean bead of black weather strip adhesive to seal the cut edges.Let the adhesive dry for at least an hour before you do anything else around the case.I did mine and its not to hard you just have to be very very careful and take your time.

    Blower Motor - REMOVAL & INSTALLATION

    Pick-Up models

    Fig. 1: Blower motor assembly and resistor locations


    1. Disconnect the negative battery cable.
    2. If equipped, remove the Vehicle Control Module (VCM) from the engine compartment.
    3. Remove the coolant recovery reservoir.
    4. Disconnect the blower motor cooling tube.
    5. Unplug the electrical connector(s) from the blower motor, as necessary.
    6. Remove the blower motor-to-case screws, then carefully withdraw the blower motor from the case.

    To install:
    1. Install the blower motor to the case and secure using the retaining screws.
    2. Engage the electrical connector(s) to the motor, as necessary.
    3. If moved on early model vehicles, reposition and secure the A/C vacuum tank.
    4. Connect the blower motor cooling tube.
    5. Install the coolant recovery reservoir, then if equipped, install the VCM.
    6. Connect the negative battery cable.

    Utility Models
    See Figure 6
    1. Disconnect the negative battery cable.
    2. If equipped, remove the Vehicle Control Module (VCM) from the engine compartment.
    3. Remove the coolant recovery reservoir.
    4. Disconnect the blower motor cooling tube.
    5. Unplug the electrical connector(s) from the blower motor, as necessary.
    6. Remove the blower motor-to-case screws (the lower screw is on the bottom front of the cover).
    7. Disconnect the harness from the blower motor.
    8. Use a razor or utility knife to cut through the cover on the cut line as neatly as possible because the access cover has to be reinstalled.
    9. Starting with upper half of the cover, tear the remaining part of the access cover from the remaining portion. Then remove the lower half of the cover in the same manner.
    10. Remove the blower motor assembly.

    To install:
    1. Install the blower motor assembly.
    2. Connect the two halves of the access cover together using the three flange clips.
    3. Using black duct tape, place a piece of the tape along the bottom lower edge of the lower half of the lower cover only. The tape has to be the full width of the cover.
    4. Install the access cover onto the case.
    5. Install the screw and align the cut areas.
    6. Seal the cut areas using black weaterstrip adhesive. Do not use RTV to seal the assembly. The weatherstrip adhesive bead should be as straight as possible to ensure a neat and professional finish to the cover. Allow the adhesive to set at least 15 minutes until it skins over.
    7. Attach the electrical connections.
    8. Attach the cooling tube and install the coolant recovery reservoir.
    9. If removed, install the VCM.
    10. Connect the negative battery cable and refill the coolant reservoir to the proper level.
