Blend door actuator replacement instructions

Good afternoon,

You need to rotate the white shaft to the same position as the old one. It will turn but maybe a little stiff.

Once you install it the actuator must be calibrated.

Note: Because the battery has been disconnected as part of the removal procedure the HVAC module will initialize and calibrate the actuators when the ignition switch is switched to the "on" position. The purpose of the module actuator position calibration is to allow the HVAC module to reinitialize and calibrate the actuator stop points. Calibration of the actuators will take approximately thirty seconds.

Turn the ignition switch to the "on" position and wait thirty seconds before verifying correct temperature blend door actuator operation.

Okay, you can plug in the electrical connector, turn on the key and change the command from heat to cold until it lines up.

Just to be sure, you have an issue with the air coming out of the center defrost vents but not the outer vents?

here is a guide on a blend door and while this is a mode door issue it gives good info.

This would be a mode door issue so I attached the info below from the manual on how to replace this.

Please run through this material and we an go from there. Thanks

Hello,

Here are two guides to help walk you through the repair and diagrams below to show the blend door actuators and their locations. Check the vacuum supply to the actuators

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Chech heater core hoses .. if they are getting hot check blend door is opening correctly

DESCRIPTION
Heater system is a blend-air type, consisting of a control panel, blower motor and plenum assembly. Blower motor is located in plenum assembly, under instrument panel. Plenum assembly contains heater core, floor/defrost door, panel/defrost door and electric motor actuated temperature blend door. See Fig. 1 .

INSUFFICIENT HEAT
Check for low coolant level. Check for pinched, damaged, collapsed, or improperly routed heater hoses. Ensure engine is not overheating. Check for plugged or partially plugged heater core.

TEMPERATURE CONTROL KNOB
Temperature control knob controls a blend door potentiometer which controls an electronic temperature blend door motor. Temperature blend door motor provides a variable number of temperature blend door positions. When temperature control knob is in COOL position, temperature blend door shuts off airflow to heater core. When knob is in WARM position, air is directed through heater core. When knob is in intermediate positions, heated air is blended with cooler incoming air to achieve desired temperature.

Hello,

It sounds like the temperature blend door actuator has gone out. Here is a guide to help you see what you are in for when doing the job.
