    The resistor is located on the passenger side of the vehicle. The glove box will need to be removed to access the resistor. I have a video of the procedure that will show removal and replacement.

      It doesn't get any better than what I sent you. Lets be honest here, your not able to perform the repair yourself and your expecting it to repair itself.

    I could explain in lots of words but it seems easier if you just watch the YouTube video of another person doing the job of replacing the blower motor resistor. Do you agree?

      Remove the glove box liner, remove the lower panel under the dash, the blower resistor is located right next to the blower motor in the air duct, just watch the video.

    How do you replace a blower resistor


    the blower motor is usually under the dash on the passenger side the resitor will be near it on the outside or you may have to pull the blower motor and it could be in there the motor is not hard to pull

    1997 chevy silverado blower only works on high and then stops working after a few minutes. High is also very weak.


    This is likely a common problem associated with the blower motor resistor pack.

    When one of the resitors go bad it will only work on a higher setting, until all of the resitors go bad.

    The part is not expensive, typically around $30-$40. In most cases it can be replace by you.

    Sometimes it can also cause the fan speed switch on your dashboar to go bad, but this is not typical.

    Check out this video from showing how to replace the resitor pack: 1A Auto Demonstrates how to change...

    The fan switch only works on level 5 out of 5... is this the selector switch?


    You probably have a faulty blower motor resistor, this electronic part controls blower motor fan speed. This part is located near the blower motor, unhook the electrical connection and you will see 2 screws holding the part in place. This part looks like some type of circuit board, Good luck, Gary

    Front blower only works on high, what part do i


    There are two things I can think of that may be causing your problem. First the blower switch in the dash may be bad if you do not have an electronically controlled blower, if you do it could be the control unit itself, but usually they stop working alltogether. The other part which may be bad is the resistor pack on your blower motor.

    If your blower has four speeds on it like most blowers these days then this resistor pack will have four resitors mounted on it. They look like coiled wires. These resistors vary the voltage coming from the blower switch so you have different blower speeds. Kinda acts like a filter dropping the voltage for the lowest blower speeds incrementally.

    If you want to diagnose this yourself it shouldn't be too hard. You will need a 12 volt test light or a multimeter to test for voltage. The blower motor should be located unther the hood of your vehicle on the passenger side against the firewall. It looks like a round black box with wires going to it. Where the wires connect to it the resistor pack is on the other end of the connector inside the motor housing. There are usually two screws or bolts holding it into the housing. If you take these bolts out it should come right out. You can visually inspect it and you may notice some charring on the circuit board where the resistors are.

    I would measure power with you test light from the connector before it goes into the resistor pack. If you are receiving power at all blower settings then your blower switch is likely good since this feeds the signal to the blower motor.

    You can then use a multimeter to ohm out the resitors on the resistor pack. If any of them show to be open you have a bad resitor coil there. You have two options at this point, you can unsolder the old resitors that are bad and try and replace them with comparable resitors from radio shack. Or you can go to rockauto.com and order a new resitor pack. They run about $16.00-$20.00.

    replace the blower motor speed control resistor 1st then the blower motor if the resistor doesn't fix the problem. Below are instructions to replace the resistor.

    The blower motor resistor is located on the back of the blower motor housing under the dash on the passenger side. It can be difficult to get at, but it is doable. Be ready with the ibuprofen the next day for your sore back. Remove the cover panel from beneath the dash on the passenger side. Unplug the power 'ribbon' wires leading to the resitor. Unplug the wires that lead from the resitor to the blower motor housing. There are usually two, one black and one purple that share the same plug. Remove the short hose that leads from the blower motor housing to the ventilation system ducts. Remove the blower motor by removing the three hex screws that hold it in place. Remove the resistor by removing the three hex screws that hold it in place. The resistor is right against the firewall so two of the screws are very difficult to reach. A slender flexible socket extension will make the job easier. Attach the new resistor in place using the same hex screws. Only 1 or 2 of the original three are needed (the part is very light) if you do not feel like fighting with the ones next to the firewall. Reatach the blower motor and reconnect the hose. Plug the power cable wires back into the resitor and the wire from the resistor back into the blower motor.
