    How do you disconnect the resistor from the wiring harness? Can you pull the harness down?

I thik it is located behind the fan speed control itself. The rheostat, ( they are actually called that instead of resistors) is part of the whole assembly. Rheostat are made of nichrome wires that are would around heat resistance material such as a mica. I imagine you can buy nichrome wires in an electronic parts shop, and change the burnt ones in the fan speed control module.

    The resistor that you are refering to is part of the whole assembly. They are not convenient to take out. From reading your question I think you better just change the whole assembly.

The heater fan on my 1993 f-350 has become really loud. I only have hi speed which I understand may be a resistor issue but how do I remove the fan and motor assembly to inspect it?


A heater blower motor resistor is an electronic device with three or more progressive resistors that allow the heater blower motor to operate at slower speeds. The highest speed of the heater blower motor is not controlled by the resistor, so when the resistor fails, the fan will often work on the highest speed setting, but not the lower speeds.
To resistor is generally located under the dashboard and under the hood, near the blower motor . The resistor's electrical connector is disconnected, the resistor is removed and the new resistor is installed. On some vehicles it may be easily accessible, and on others it may take partial dashboard removal to replace the resistor.
Look under the hood, generally the wiring for the Blower resistor is attached to the wiring to the blower motor itself
It's inboard & below the motor, near the accumulator. You can see it standing beside the passenger fender. it's the off-white connector behind the L heater hose above the vacuum reservoir & the white WARNING sticker

Locate blower motor resistor on 2006 Passat 2L Turbo


The resistor is not on the motor. Go into the passenger foot well and look underneath the dashboard right at the back. There you will find a foam cover that just pulls out. Remove the foam and you will see a clip on connector plugged in a white insert. The white insert is the resistor. Firmly pull the white insert out of the dash and the resistor is in your hand

2000 grand prix blower motor only worked on high for awhile now it doesnt work at all


in alot of cases the blower motor resistor burns
if you follow the blower connection to left you will the resistor plugs right in to the blower but make sure you check it before you buy it take it off and inspect it you will see burns on harness and resistor
its under the passiger side dashboard you will see the blower and to the left is the resistor i think you will need a 9/32 socket or 7mm its held by one screw
good luck

The heater blower in my 2002 sentra is only woking when on the highest setting...do you know what the problem could be?


The blower resistors have gone bad and needs to be replaced.

The 2002 Nissan Sentra blower motor resistor is located near the blower motor itself, which can be found under the dashboard, on the passenger side of the car.

To access it, you have to remove the glove compartment and the isolation panel that covers the bottom of the blower. Do the following steps:

  1. first, locate and open the glove compartment on the passenger side;
  2. remove the four upper screws and slide the door lock bracket out;
  3. pull out the two pins at the inner bottom corners of the compartment;
  4. take out the glove compartment assembly;
  5. remove the two screws retaining the isolation panel and slide the later out.
Looking under the dashboard, you can now see the blower motor and, on its left side, near the firewall, the resistor block brown connector.

To take out the blower motor resistor:
  1. remove the white plastic bracket that faces it;
  2. unplug the brown connector;
  3. remove the two screws on the resistor's socket;
  4. pull the resistor block out.
The resistor block is actually a PCB ("Printed Circuit Board"). The traces printed on this board have different electrical resistance, and are used by the control assembly to vary the speed of the blower fan.

I believe Auto Zone or Parts Source has the blower resistor you need. Good luck

Blower reisitor, 1998 Toyota Tacoma


The blower motor resistor is located in the heater box area, which is under the dashboard on the passenger side. You will find the resistor in the large squarish tube that leads to the center of the dash from the blower motor housing (right to left on an american vehicle). Unplug the large black wiring connector, remove the 2 phillips screws and the resistor is ready to pull out of the heater box.
