How do you remove a mode door actuator?
How do you remove a mode door actuator?
Remove the pushpin retainers, then pull the duct off the HVAC case. Disconnect the wiring harness from the mode door actuator — the mode door actuator has a white gear extending from one side and is the lower of the two actuators. Remove the screws from the actuator. Pull the actuator from the HVAC case.
How do you reassemble a mode actuator?
The mode door levers must be in the this position in order to reassemble the mode actuator to the HVAC case. Lubricate the pivots on the mode door levers and the channels on the mode actuator cam before assembling. Align the mode door levers with the cam slots, as noted on disassembly.
Where are the mode and blend door actuators located?
Because the blend door and mode door actuators are typically located side by side and look nearly identical, it may be hard to distinguish which part you are replacing. Below is an example of an HVAC Unit Housing, from a 2010 Chevrolet Traverse.
How do you replace envoy mode door actuator?
It is fastened from behind on the very right by two bolts that are hidden and impossible to reach. On the side the can see, there are two 1/2″ nuts that are tack-welded to the part. Get your 1/2 deep 3/8 drive socket and a short ext on them and crack the welds loose and remove them.

How are actuators control vehicle mode and temperature?
How actuators control vehicle mode and temperature. A plastic case under the dash contains the air conditioner evaporator-core and the heater core . Air flows through the case and a series of doors that the actuators open and close to control this flow. The position of the doors determines where air flows and the temperature.
What is mode door?
The mode door is what changes the direction of the air coming out of the vents. Moving the door to different locations changes whether the air comes out of the defrost, floor, dash vents or a combination of both. The vehicles listed below use an electric motor mode door actuator. How a mode door actuator works.
What does the mode door actuator do?
Mode Actuator. The mode actuator is an electronic stepper motor with feedback potentiometers. The HVAC control module sends signals to the mode door actuator through the mode door control circuit. Zero volts drives the actuator in one direction while 5-volts moves the actuator in the opposite direction.
