Dodge Ram '95-'02
This is a kit to do a complete repair on the blend door malfunction that is common to 95-02 Rams. Every Ram in this range either has, or will have, this common failure.
If you feel uncomfortable installing the repair yourself, go Here to find a HeaterTreater certified garage near you.
The Dodge is relatively simple compared to our other HeaterTreater products. The Ram has a metal blend door and a metal connector on the actuator motor. The problem is use of a plastic interposer to connect the motor to the blend door axle. The pictures show the plastic OEM component and the steel replacement. Some early RAM's have a mechanical slide lever control on top of the box. If your truck doesn't have the actuator motor on the bottom of the box, it is the older version and our kit for the electronic model will not help.
The actuator motor is located under the passenger side dash and you can use the second picture to locate the motor module. You can observe movement of the motor by adjusting the temp control knob with the HVAC system on. The module is held in place with two phillips screws and is removed by pulling straight down. The black interposer that the motor fits into can usually be removed with your fingers, but you may need a pair of pliers. Again, just pull straight down on the black plastic piece and it will come loose. Inspect the interposer for any signs of cracking or chipping.
The Dodge actuator motor has a full 360 degree rotation capability with no built in limit stops. The internal gears have a slide connector that moves along a variable resistance strip and uses the different resistance readings to gauge the position of the blend door. When the connector breaks, the motor spins past the point where a valid reading can be taken and the computer control “loses it’s mind” and shuts down the motor. The most common observation is a cracked interposer and seemingly non-functional motor.
The HeaterTreater provides an unbreakable replacement interposer and fully illustrated instructions on how to open the motor case and re-index the motor gears to restore proper operation. Generally the Dealer will recommend a new motor(including another cheap plastic interposer that will break) at a substantial cost. The HeaterTreater will restore functionality that will outlast the truck at a significantly lower price. The replacement component is good to solve a HVAC problem, but also can easily be inserted into a functioning system to avoid the problem occurring in the first place.

Failure of your heat and/or A/C in your Jeep Grand Cherokee is usually due to the failure of the connector between the blend door and actuator motor.
Heater Treater replaces the cheap, plastic connector with steel. Replacing the connector with the same plastic part from the manufacturer WILL result in continued problems — the same system design problem that caused the failure in the first place WILL happen again.
Heater Treater attacks the root cause of the failure by constructing hardware that is designed to meet the rigors of normal operation of the HVAC system, and last for the life of the Jeep. Note that some early vehicles used a mechanical cable control for the blend door. Check that you have an actuator motor on the bottom of the box at the intersection of the transmission tunnel and firewall to make sure that the control is electronic. The cable system will be on top of the box and will be a mechanical issue with the cable.
The 2002 Ram was a changeover year. If you have an ’02 you should check this listing and the ’02-’08 listing to see which system you have.
