## Description

Full description not available

## Features

- Calibrated to OEM Specifications; Tested for impact, wear and fatigue to ensure quality and durability; Built under strict quality control standards
- AC Blower Motor Resistor is used on blower drive for automotive air conditioner; It changes the duty cycle of the PWM wave that drives the fan according to the size of resistance signal from the air conditioner controller, thereby adjusting the fan speed
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions
- If you cannot adjust the air speed properly with your AC control or no reaction from your air conditioner system, maybe you need a new Blower Motor Resistor; AC Blower Motor Resistor is mounted on lower passenger side dash ( beside the Blower Motor) and is easily assembly by simple tools

## Questions & Answers

**Q: Will this work on 2003 wj 4.7 ho. advertisement says 99-2004 but the fitment guide doesn't list 2003 4.7 ho**
A: It should, the 2002-2004 model years were updated to the 4.7 HO engines for limited and up trim levels. The regular 4.7 powertech ran from 99-01.

**Q: Will this resistor fit for 1999 Jeep Cherokee limited ac resistor?**
A: Hello friend, it will fit for 1999 Jeep Grand Cherokee Limited Sport Utility 4-Door 4.7L V8 and 1999 Jeep Grand Cherokee	Limited Sport Utility 4-Door 4.0L cars.

**Q: will it come with a instruction?**
A: Hello frined, it will not come with a instruction but it's easy for intallation. First, Remove the negative battery terminal; Second,Locate the blower motor resistor on the passenger side under the dash board. It is mounted to the the blower housing near the blower motor; Third, Disconnect the electrical connector to the blower motor resistor; Fourth, Remove the screws or bolts to the blower motor resistor and remove the resistor; Fifth,Installation is the reverse of the removal.

**Q: Will this work with a dual zone system.**
A: Yes. Auto climate control.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked perfectly. Exactly what I needed
*by J***N on May 18, 2023*

The picture is of the old one I replaced. I have a 2000 Jeep Grand Cherokee. And the HVAC Blower Motor Resistor died on me. So I ordered a new one. And it works perfect.Pain in the neck to remove and replace. But was well worth it. Without a working one I had no heat or ac.Fast shipping and delivery. A+++

### ⭐⭐⭐⭐⭐ And then, there was Air Conditioning!
*by E***I on August 11, 2020*

After watching a buddy of mine try to come up with five different (terrible) back yard solutions to fix his mother's AC in her 2000 Jeep Grand Cherokee Limited and one order of the incorrect part which he said was the right one, that's when I stepped in and ordered this part. It is a direct fit replacement and fits perfect. I did, however, have to go to our local Napa andalso purchase a Dorman Blower Motor Speed Resistor Harness Pigtail part #973-304. I had to purchase the connector after a little bit of research on Google I found out that the resistors on these jeeps hit a certain age and just begin heating up until the heat to a point where they actually overheat and melt black resistor (control) box and/or its contents and wiring attached. My friend's mom's had melted the circuit board inside the box AND the three wire connector going into the box beyond repair.A little piece of extra information that may save you the headache of researching it. When you get the Dorman connector it will come unassembled and with too many wires, which may throw you off. Before you begin, make sure you gather a few good electrical shrink butt connectors and a piece of shrink tube wide enough to go around all 3 wires and butt connectors. Electrical tape had been used under her dash prior and due to the heat of the wires the tape had become a gooey, sticky nightmare. IMPORTANT: Prior to cutting the old 3 wire connector from under the dash make note of which colored wire goes into which position of the connector when it's snapped in Black goes on what I would call the outer side of the box, the middle is the brown/yellow and the red wire goes what i would call the inner (middle of the box when snapped in). Once you note the lineup go ahead and cut the connector leaving a good length still attached to the vehicle and keep all three wires an even length. Now the colors of wiring in the replacement kit are blue and green. Why? I have no earthly idea. Use two of the green wires (they are fatter) and connect one to the black and one to the red wire using your shrink butt connectors. Then connect a blue wire to the brown/yellow via same procedure. After all three wires are connected slide your shrink tube over all three wires but don't shrink it up yet so it's easy to make sure you have the correct wire color coming down into the correct slot in the connector. Slide the little gold contacts into the correct slot of the connectors and after all three are in and you verify they are correct matchup as before push in the little retaining clip behind. Go ahead and heat your shrink tube carefully around the three butt connectors nice and snug. and thats a wrap. plug into your freshly installed black box, plug the new 2 wire connector into the blower and you're done!I would have taken pictures of all of this had I thought of it sooner. But hopefully that helps save someone from the nightmare we went through. Cheers!I feel it might also be helpful to tell you why the incorrect part was ordered initially, The reason the incorrect part was ordered prior to this one was because there is no replacement part sold that has both the 2 wire and the 3 wire connectors with it. So prior to my involvement in the project I had my buddy look at the amazon search results and tell me which part to order and he was concerned about the three wires, because that is what had burned, so he picked the only part that had 3 wires included.

### ⭐⭐⭐⭐⭐ Perfect fit works great
*by D***O on September 12, 2024*

I put this part in my customer vehicle and he is happy, never complain again
