        Solution for 2000 Tahoe stuck on heat

            Comments about Dorman - OE Solutions HVAC Air Door Actuator:

            This was a perfect fit on my 2000 Chevy Tahoe LT 5.3L V8 4WD. This solved my problem of the hot/cold mixer (blender) not working anymore (I only got hot air no matter what I set the dial at.) A few notes: 1) On my Tahoe, this part is located under the glove box on the far left. 2) To get to this area, you must remove the housing under the glove box, and one of the screws to remove this housing is very difficult to get to. 3) This is NOT the part to buy if settings 1 through 5 on the blower speed don't work. 4) This is NOT the part to buy if the face/foot/defrost dial is not working.

                My 2001 GMC truck was stuck on heat outputdue to a faulty acuator. I had to return the original unit since it appeared that someone had previusly opened the package and energized it before mounting, which caused the motion range, according to the indicators on the unit, to be out of range or calibration. The replacement unit worked well. Good value for the money!

                    This part took about two minutes to install, once all the access panels had been removed. It even had a warning message to wait to engerizing the motor until after it was installed. This was very helpful to me as I like to check out parts before I put things back together. After following their directions there were no problems getting it to work.

                            Hi, I'm glad to assist you. The Dorman - OE Solutions HVAC Air Door Actuator (Part No. 604-101) is the temp actuator and the Dorman - OE Solutions HVAC Air Door Actuator (Part No. 604-106) operates the recirculation door. if you are having a temp issue then the part #604-101 might be needed. However, without the presence of your vehicle we would not be able to properly diagnose it, nor provide you with a 100% answer. I would suggest that you take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.

                          Does this control air flow to floor vents? I can't get any air flow at floor vents.
                          Also, if it is, where is it located & how do I get to it to replace it.
                          Are directions included?

                            No it does not. This part# controls the blend door. The mode actuator is what directs the airflow to floor, defrost and vent.

                            I used one of these to replace the underdash actuator. Common amongst Tahoes and Suburbans is the actuator failing to the hot side; not fun in the summer! This is the actuator that frequently fails.
