If you were looking at this from under the passenger side of the dashboard it is on the left side of the blower itself it is a 2" x 4" black block. You will need to have a heat welder to remove this and install a new one since it is secured with heat type plastic rivets.

to guest: this resistor is what applies power to the blower so when it shorts out it will make the blower motor run non stop even with the key out of the ignition.

Usually inside the airstream (thus it gets cooled)

Follow the wiring from motor around the air intake area. At some point it will dissapear inside the air box/trunking.

It should be on a largish mounting block - maybe even screwed on.

Need to locate the motor blower resistor for my 1999 mercury mountaineer, it has dual air, the resistor for the back is fine but the one in the front is bad and i cannot locate it. Please help.


If you have a manual system, you have a resistor. If electronic, you have a blower motor speed controller. Please rate if this helps.

here is info:

Control System Outputs-Manual A/C
Blower Motor Switch Resistor
The heater blower motor switch resistor has the following features:
  • The assembly is located on the evaporator housing in the engine compartment.
  • Three resistance elements are mounted on the resistor board to provide four blower motor speeds.
  • Depending on the heater blower motor switch position, series resistance is added or bypassed in the blower motor circuit to decrease or increase blower motor speed.
  • An overheating protective device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121°C (250°F) interrupting the blower motor operation in all speeds except HI.
  • The thermal limiter cannot be reset and is not serviceable.
Control System Outputs-EATC
Blower Motor Speed Control
The blower speed control is located on the evaporator housing in the engine compartment.
  • The function of the blower motor speed control is to convert low power signals from the electronic automatic temperature control module to a high current, variable ground feed for the blower motor (18527).
  • The blower motor speed is infinitely variable and is controlled by the electronic automatic temperature control module software.
  • A delay function provides a gradual increase or decrease in blower motor speed under all conditions.

How doi locate the resistor for a blower motor on a 1997 gmc sierra 1500


Hi!!
Check under dash, passenger side, if necessary, remove cover to access Blower Housing Assy., the harness has two terminals, one for the Blower Motor and one for the Blower Motor RESISTOR which is fastened by two 7 or 8 mm. screws to the Housing.
Here is a picture of the Blower Housing Assy. showing the Resistor.

I need to locate my blower motor resistor on my 1999 S-10. do u know where it is located on my s-10?


The resistor is located under the hood on the passenger side. At the back of the engine compartment you need to locate the airbox it can be identified by a circular piece that's right beside the fender on the firewall (this is your blower motor) to the right if it (looking from the front of the truck) about 4 -6" you will see a wire plug. Unplug this connector and locate the four screws that attach it to the air box. Remove these screws and pull the resistor from the housing.

Hope helps (remember to rate this answer).

1999 grand marquis were the blower motor resistor is located


this is for manual heater system. If you have electronic (digital display) you don't have one. Instead you have a blower motor speed controller.

here is info

Control System Outputs—Manual A/C
Blower Motor Switch Resistor
The heater blower motor switch resistor has the following features:
  • The assembly is located in the engine compartment on the evaporator housing toward the center of the vehicle.
  • Three resistor elements are mounted on the resistor board to provide four blower motor speeds.
  • Depending on the heater blower motor switch position, series resistance is added or bypassed in the A/C blower motor circuit to decrease or increase A/C blower motor speed.
  • An overheating protective device (thermal limiter) will open the resistor coil when the temperature reaches 121°C (250°F) interrupting the blower motor operation in all speeds except HI.
  • The thermal limiter cannot be reset and is not serviceable.

2005 Kia Sorento only blows hot and cold air on high. Is it a blower motor resistor and if it is where is it located?


If the blower moter only works on hi speed it is the blower motor resistor that is bad. The blower motor resistor is located under the passenger side of the dash next to the blower motor. It is not necessary to remove the blower motor to change the resistor.
