1995-2002 Dodge Ram HeaterTreater tm

This is a product developed by the HeaterTreater Engineers for the common blend door failure problem on 95-02 Rams. The same heater box is used on all models of the Ram truck, so this product works on all Dodge trucks in the application range. Please check our feedback to get an idea of the product line integrity and customer reaction to our products. We are committed to customer satisfaction and successful repairs of blend door problems.

<SPAN arial="" ,="" sans-serif="" ;="" color="" black="">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.

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 welded stainless steel replacement.

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. Contact us for pricing on volume purchases.

We fully stand behind our products and will provide application support through email or phone.
