Where is the blend door actuator located on a 2007 Pontiac Grand Prix


! Pontiac doesn't call it a blend door actuator .
There are Air Temperature Actuator - Left : Air Temperature Actuator - Right
Mode Actuator Recirculation Actuator Now if you would state the problem your having , we could tell you what to do , need to take dash apart or the glove box needs to come out . Do you have automatic or manual HVAC system .
Air Temperature Actuator The air temperature actuator is a 2-wire bi-directional electric motor. Two control circuits enable the actuator to operate. The control circuits use either a 0-volt or 12-volt value to co-ordinate the actuator movement. When the actuator is at rest, both control circuits have a value of 0 volts. In order to move the actuator, the HVAC control module grounds the appropriate control circuit for the commanded direction. The HVAC control module reverses the polarity of the control circuits to move the actuator in the opposite direction.
The HVAC control module determines the door position by counting motor pulses on one of the control circuits. These pulses are small voltage fluctuations that occur when the brush is shorted across 2 commutator contacts as the motor rotates. As the actuator shaft rotates, the HVAC control module monitors the voltage drop across an internal resistance to detect the pulses. The HVAC control module converts the pulses to counts with a range of 0-255 counts. The HVAC control module uses a range of 0-255 counts to index the actuator position.

I an needing wiring diagram and harnesses for a 2007 Ford mustang


Your clicking noise is coming for one of the electrically controlled actuators for the HVAC system ! heating , ventilation , an air conditioning . They have plastic gears inside that wear out , break an when they do they click ! You need to take the lower dash panels off an stick your head up there as best you can an find the clicking ! This is what your looking for ! mode door or blend door actuator ! defrost door actuator,air inlet door actuator . The Suction accumulator is under the hood in engine compartment .The suction accumulator is located at the LH rear of the engine compartment. The suction accumulator is used to prevent residual liquid refrigerant from reaching the A/C compressor after leaving the evaporator core. The suction accumulator allows the accumulated heavier liquid refrigerant and oil mixture to re-enter the compressor suction line at a controlled rate. A desiccant bag is mounted inside the canister to absorb any moisture which may be in the refrigerant system.

Usually it is a shaft that attaches to the blend door and the actuator. Sounds like the door is broke and the HVAC unit must come out to replace the door as the unit has to come apart.

My 2004 Avalanche ' heating system will not heat. No matter what the setting it either blows no air or cold air and it is 25 degrees outside so this is a problem. The engine is up to temp and I have tried...


The most likely cause is a failed blend door actuator; however I recommend a little troubleshooting. First, can you hear a clicking sound behind the dash when you turn the setting to hot? If yes, it is certainly the actuator stripping its gears. If not, check to make sure the heater hoses are both hot as they connect to the heater core at the firewall (in the engine compartment). If one or both of the hoses do not get hot, there is a blockage caused either by an air bubble or a stuck water control valve in the heater hose. If the hoses are both hot, the indication is again the blend door actuator.

Below are instructions for replacing the actuator. Look at the diagrams carefully--the big arrows point to the front of the truck and the actuator is on the side of the heater box above the outlet duct that runs to the driver's side of the floor. Also, the actuator is expensive, so I recommend you make sure it's bad and shop around a bit to get a good price. To check out the actuator, first see if you can turn the blend door by hand. If you can't turn it, maybe it's jammed. Also, reconnect the actuator after removing it and see what it does when you turn the heater to hot.

Removal & Installation
  1. Remove the floor air outlet duct extension (1) from the floor duct (2).

Afternnon, just wondering about the best way to locate the blend doors in the hvac box without ripping out the dash on my 2000 jeep grand cherokee. Thanks in advance. Duane


y9ou can gain access to the driver side blend door actuator by removing the glove box. The actuator will be in the left corner of the glove box opening. If you remove the actuator you will be able to turn the pin. If you can turn it 360 degrees the blend door is broke.

If your lucky its only the drivers side. If you get the repair kit from chrysler it will come with instructions with pictures on how to replace the blend door without pulling the HVAC unit/Dash. If the passenger side is broken the HVAC unit will need to be removed.

Heater treater (google them) also have a metal blend door replacement and instructions online on how to replace them without pulling the HVAC housing.
