      1) Open the hood and then disconnect the negative battery terminal from the battery using a small hand wrench.
      2) Open the passenger side door wide and then remove the trim panel (kick-plate) underneath the glove box. Use a screwdriver to remove the clip retainers of the trim panel and then unplug the wire harness from the courtesy light to remove the panel completely.
      3) Unplug the wire harness to the blower motor by depressing the plug lock inward and then pulling it off the opposite plug connection.
      4) Remove the three retaining screws holding the blower motor in place using a 1/4-inch drive ratchet, extension and suitable socket. Remove the motor.
      5) Compare the old motor to the replacement motor for basket-wheel size, flange shape and plug connection. Some aftermarket blower motors for the Grand Prix may match identically except for the plug connection. If the flange or basket-wheel length does not match, you'll need to return the blower motor to the parts store to find one that does (take the old motor with you). For the wire harness plug connection, you can simply snip off both the motor and harness plugs and rewire by stripping the wires with wire cutters, inserting the same colored wires into the butt connectors and then crimping the butt connectors to secure the wires.
      6) Insert the motor into the housing and reattach the three retaining screws. Plug the wire harness back in (or rewire as described in Step 5).
      7) Reattach the negative battery terminal with the small hand wrench. Test the blower motor for operation by turning the Grand Prix to the accessory power position (the ignition key placed two clicks forward in the ignition) and turning on the blower using the dashboard fan controls.
      8) Replace the trim panel and retainers.

      The parts are readily available; try these on-line sources;,,,, - to list only a few possibilities. In fact, they (RockAuto) lis tthe replacement blower motor from around $36.00 for your vehicle.

      If this problem has existed for a while, the cause may be that the evaporator core fins are blocked (on the engine side) with debris. I think you can remove the blower motor resistor and see the core fins. I did this once with a similar problem and I vacuumed the debris out through the access hole by removing the blower resistor from the engine compartment and it added a huge amount of airflow.

      Did you use after market blower motor?If so you may have motor spinning the wrong direction.Switch the wires to motor to correct air flow.

      I agree. I forgot that completely. You are probably right, reversed polarity and spinning backwards. So it is a vacuum now..LOL

    Should I Buff or Paint
    I was dinged in the grocery store parking lot. My male friends say that the damage can be buffed out since it looks as if the top coat was scratched away. My question though is whether or not the compounds used today are as durable as having the area of the car ...

      Generally, yes - the buffing can restore minor scratches without harming the basecoat / clearcoat applied at the factory.

      Thanks Jimm! Obviously I won't be paying for the repair, but it's nice to know that when the body shop tells me the same thing that I'll know they aren't telling me to take the cheaper option just to make the insurance company happy.

    Headlights only work on high beam.
    Normally headlight come on when car is started. Noe i have to turn on with switch. Recently I put on high beam and then back to low, low beam went off and stayed off. I checked fuses, seem ok. Could the problem be in the switch which is on turn signal selector?

    The instrument cluster gauges have stopped working and all warning lights are on.
    This happens when the key is turned on, and there is power to this system. It happens with the engines running and when its not. Any ideas.

    Electric car seat does not go up and down
    motor is fine
    • HouseCallAuto
      10/31/2013 HouseCallAuto
      There are 3 separate motors. Did you know that? Give me better detail to work with. the rear vertical motor moves the rear of the seat up and down. The front vertical motor moves the front of the seat up and down. The horizontal motor moves the seat forward and rearward. The both vertical motors can operate independently from each other or can turn on together and raise or lower the entire seat. So now tell me, what is the seat still able to do?

      Replace the Blower Motor Control Module. For the heated seats check the 20 amp HTD SEAT fuse in the instrument panel fuse box. If the fuse is burnt it means that you have at least o0ne bad seat heating elemant somewhere. This fuse controls both seats.

    Heat don`t work when you turn them on the interior lights is on
    when I turn on heat seats high or on low the seats don`t heat up
    • HouseCallAuto

      Check the 20 amp fuse labeled TRUNK / HTD SEATS in the underhood fuse panel. If the fuse is good see if there is 12 volts at the fuse. if voltage is ok you likely have a bad seat heater element. Yiou did not say if this was happening with driver or pass eat or both.

    Dash lights and gauges quit working
    I was driving down the road and all of my dash lights went out and now the gauges are stuck in an upright position. Is this a fuse problem or something else?

      Heads Up Display is junk but apparently if you Google "grand prix HUD repair" you will no doubt find a suitable page to walk you through a repair of this HUD which you will want to do seeing as how a new display is $250 on the net plus shipping and handling with part # 10387483. Its not difficult and involves repairing a broken spring mount.

      You have a faulty ignition switch. Probability here is greater than 90%.

      The heater A/C control is using a vacuum source to operate the heater defroster valve vacuum actuator - the A/C bi-level mode valve vacuum actuator. Over the time the hose crimps were loose from the AC controller and lack of vacuum source it couldn't operate properly the vacuum actuators.

      I have seen the plastic knob go bad and actually slips on the selector shaft. Try switching the knob from the temp selector and see if that temporarily solves it.

      Your vehicle likely has more than 1 fuse box. Check all your fuses especially for instrument panel and gauges and courtesy lights. The dashboard lights are operated by the headlight switch and dimmer switch. You can test the switches to see if the dash lights are getting power out of the switch. The trunk light is run by a separate switch inside the trunk usually attached to the lock mechanism. Locate the switch and test for power to the switch and thru it to the lights. You should be able to at least identify the wires on these parts by color on the wiring diagrams for the headlights and the interior courtesy lights. Just identify the light on the diagram that is not working and trace the wire to the switch and test for power at every connection.

      Replace the window regulator. Remove the interior door panel for access to the regulator.

      Check the many on-line auto parts sources, such as;,, and - to list only a few sources. For example, they (Rock Auto) list the driver side front window regulator assembly from around $9.50 for your vehicle.
