Dash removal to check actuator motor

AC Actuator ?
The temperature control regulates the HVAC system air temperature in any mode. A temperature control cable mechanically links the temperature control to the temperature door. Your hearing stuff inside the blower motor housing , like leafs or someother de·bris .

Because your vehicle has no electric actuator .
Disconnect the electrical connections from the blower motor.
Remove the blower motor retaining heat stakes with a chisel or a screwdriver.

There are little doors under the dash that direct the air to either the vents (blows at your face), the defrost (blows at the windshield), or underneath (blow to your feet area) - these doors are controlled by what's called actuator/s and they are usually controlled by vacuum or cables - when the air won't change directions it can be either the vacuum switch, the vacuum line disconnected, cable disconnected or the actuator itself can be stuck or bad...

You also have a heater valve that allows the heated coolant to enter the passenger compartment into a heater core (small radiator to allow heat to transfer into the air when the blower blows air across the core) - this can also be vacuum controlled or cable controlled or electronically controlled - if it malfunctions then you may not get any heat into the passenger compartment - you will have to determine if the valve is not getting the signal to open or is bad and will not open - good luck :O)

Your blend door actuator is stripping it's gears. You may be able to see the actuator by looking under the dash above the passenger's feet. The actuator looks like the picture below. If you can, take the connector off and unscrew the actuator from the heater box. Make sure the door will rotate by hand. If it does, replace the actuator. The part is $36 at autozone. If the door is jammed, you may have to remove the heater box to repair the door. That would be a big job...
Let me know if you have any questions.

not very good one to fix , somtimes cables that operate opening and closing of air vents bellow dash separate , and stop from opening , i think you will find most things under foot panels near passenger feet . and center consol near passenger feet . , you may need to take of those panels to see is you can visially see anything .

Sounds like the heater blend door. The actuator may be stuck or broken. The actuator opens and closes to adjust for the heat setting in the car. You might be able to take a coathanger and manually open the door if you can get to the control arm. They are usually hard to get to and pretty expensive. It is located under the dash at the heater core box. Good luck.

There is a door actuator motor that is not working,removal of the dash might have to be done to access the actuator motor to change it out.

no u must remove the dash.

Look up in the vents with a flashlight, some times an errent object placed on the dash finds its way down the defroster vent and into the plenum. These items tend to keep the doors that dirrect the air from moving.

your actuatior foe the drivers blend door is stuck. try unhooking battery for a few minutes have both on heat and hook back up and start up. the actuators will run thru a learn mode and sometimes this will free up.if not you will need an actuator

Blend door for passenger side or blend door motor has failed. Very big job to remove dash and work on it. Except the door motor is accessable from the glove box.
