This blower motor resistor is a new, aftermarket replacement part. It is just what you need to bring your heating and A/C blower system back to good working order! On most vehicles it is mounted to the HVAC unit inside the passenger compartment. It can be accessed from the passenger foot well area.

Specifications:

  • New, not remanufactured or rebuilt
  • Direct replacement for original resistors that may have a angle plug
  • Built to strict quality control standards
  • 100% tested prior to leaving the factory
  • 7 & 2 Terminal connection
  • 2 Hole Mounting Flange*
  • For models that have a front and a rear blower motor, this replaces the FRONT RESISTOR

*There are multiple options available for these applications. Please verify your resistor has a 2 hole mounting flange.

Note: For 2007 truck models, the Classic Style has a crease down the center of the door skin where on the new body styles, the door skin is smooth. This part is for the Classic style truck.

Our electrical and electronic parts are subject to strict quality control testing. Please ensure proper diagnosis of this item before purchasing as the item cannot be returned once installed or plugged in.

I bought this part and a blower motor actuator. I was not sure of the parts to order so I contacted the store and Cameron assured me that these were the correct parts for my vehicle. These parts at the dealer (OEM) wee over $400.00 combined. Thanks Cameron for your EXCELLENT help with my order. I'll be a repeat customer.

How'd you do that?
Judging from when it arrived, 1a must've shipped it before I even knew I was going to order it. How the h### did they do that??????

My AC is not blowing on the High speed, It will fluctuate on speeds based off the RPM of the engine is going, for example, when I stop at a light, the AC fan speed will sputter. The AC is not working reliably, at times It will not turn on at all. Is this part a possible fix? Thank you
Danny on May 1, 2017
BEST ANSWER: The resistor pack only controls the operation of the blower motor not the operation of the AC unit. If the blower motor works at all speeds when the AC is turned off then the problem is not with the resistor pack. Not sure what you mean when you say the AC does not turn on. Do you mean the indicator light for the AC unit does not come on when you actuate the AC switch or do you mean that the blower motor does not come on. Again if the blower motor does not come on or works intermittently at the different speed settings then the resistor pack is bad.
My blower motor plug in has melted where it plugs into the blower motor, this is the 2nd harness to melt, would the resistor be putting to many amps into the blower motor and melting the harness to where it won't work?
Roger P on Dec 5, 2017
BEST ANSWER: There is a history with this blower / resistor / harness. My guess is replacement resistors are not the best quality (lowest China bidder), the blower is oversized for the resistor and the cable or connector is of insufficient current rating. A poor quality resistor will allow too much current to flow causing the connector and harness to melt. I think you will find that people are replacing the harness with a heavier gauge wire. And I would buy a quality, read more expensive, resistor pack like an oem one. BMW aren't much better. I've been through two in my x5 in 3 years and one in my 2000 gmc. Good luck!
What should the resistance, or on reading be?
D_windex on Jun 25, 2017
BEST ANSWER: The resistance should be the same as factory. Unfortunately we do not have the specs available.
