Where is the air vent blend door actuator on a 2000 Jeep Grand Cherokee Laredo V6 I need to check vacuum hoses attached?

Answer 1

• If you are looking for the mode door vacuum actuators they are located to the left of the heater. If you are looking the blend door actuator motor it is located behind the glove box.

• You have to remove to glove box to get to the actuator. You can run a self diagnosis by holding the A/C and Recirculation buttons at the same time, then turn the left temp knob one turn clockwise. This wil give u codes to tell you whats up. Don't pay the high labor costs until you research the problem your self!! It ain't that hard to get to, but they charge a lot cuz it does take some time.

• No vacum hoses for the blend door, it is operated by an electrical actuator motor. The most common cause of your symptoms is blend-door failure. This is a design flaw created by Chrysler engineers. Basically what happens is that every 20 times the vehicle is started, the A/C system software tells the blend doors to recalibrate to ensure that the airflow is as accurate as possible. The problem is that the stop point is made of cheap plastic. The stop point connected to the actuator breaks. Shortly thereafter, the blend doors break because they cannot withstand the pressure of the actuator pushing them beyont their limits after the stop point has been broken. Passenger side is typically affected first, followed by the driver side. If the doors fall with gravity into the down position, you will maintian A/C. If you hit a bump on the road and they fall into a mixed position, you will have neutral temperature. Either way, no heat is a symptom because that is the up position for Jeep Grand Cherokees (99-2004).

• I have tried a product repair kit which will replace the plastic drive connector piece and the plastic blend doors with solid aircraft quality aluminum parts. Aluminum was chosen because it will be close to the weight of the original parts. The blend door shaft is a ½" solid piece of aluminum rod machined to fit. The two doors are aluminum sheet stock tig welded onto the door axle shaft with a foam covering applied to both sides of the door panels, all to make a one piece assembly. The second piece is the drive connector it is a ½" solid piece of aluminum rod with steel pins. The drive connector is machined to fit the actuator motor and to fit onto the end of blend door axle shaft assembly.
