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!

                • Q:

                  Have a 2002 chevy Silverado 1500 v8, fan works, hot and cold works, the mode does not work all air flowing to defroster, no matter what position. Oh recirc seems to work also. Is this the actuator that controls the mode, from defrost to floor and vents?

                  I assume this is located on passenger side towards the floor by cabin filter, am I correct?

                    A:

                    Happy to help, Jim! You would need the Dorman HVAC Air Door Actuator - Part No. 604-113 for the mode door actuator. That is to the right of the gas pedal. Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result. Place the ignition switch to the OFF position. Install the HVAC actuator. Connect all previously disconnected components. Remove the HVAC/ECAS fuse for a minimum of 60 seconds. Install the HVAC/ECAS fuse. Start the vehicle. Wait 60 seconds for the HVAC control module to self-calibrate.

                    A:

                    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.
