Only AC or heat works on the drivers or passenger side why?

The correct way is to pull the hvac unit out which requires pulling the dash. not an easy job. but you could try to undo the screws and pull the actuator out that way. it might be a little harder but save pulling the hvac and dash out.

Hello,

Turn the key on, then pull the HVAC (10 amp) fuse and wait 5 minutes. Then turn the key off and replace the fuse, then turn the key back on and the system on and it should calibrate. Did you use a OEM part when replacing the blend door actuator?

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

Cheers, Ken

Good afternoon.

The actuator is on top of the case which means the instrument panel must be removed to gain access.

Are you planning on doing this yourself?

AIR TEMPERATURE ACTUATOR REPLACEMENT - RIGHT

REMOVAL PROCEDURE
1. Remove the I/P carrier.

2. Disconnect the electrical connector (4) from the right air temperature actuator (3).
3. Remove the screws from the right air temperature actuator (3).
4. Remove the right air temperature actuator (3) from the HVAC module assembly (2).

Your car has two different types of HVAC. picture show correct one. however, before you replace it pull HVAC fuse inside truck for sixty seconds with key on and it may reset it. do that first before you spend any money on parts.

This guide will help us fix the problem.

Check out the diagrams (Below). Please let us know what you find.

The actuator that is pictured is on the bottom of the HVAC unit kind of behind center of dash and two screws hold it. The actuator in new picture is re-circulation one which is behind glove box. That can be a broken door or the actuator is bad. On that. If the door shaft is broken that can be replaced but the whole HVAC unit may have to come out.

Welcome to 2CarPros.

Since we know the system is working because it works on one side but not the other, my first suspect is a blend air door issue. The blend air door is what controls the air temp entering the vehicle.

You will need to get under the dash to replace it. If you look at picture 1, it shows location. Locate number 1 on the picture and that is the actuator for the left side of the vehicle.

Here are the directions specific to your vehicle for replacement

2. Disconnect the electrical connector (1) from the left air temperature actuator (2).
3. Remove the screws from the left air temperature actuator (2).
4. Remove the left air temperature actuator (2) from the HVAC module assembly (3).

INSTALLATION PROCEDURE

1. Install the left air temperature actuator (2) to the HVAC module assembly (3).

NOTE: Refer to Fastener Notice in Service Precautions.

2. Install the screws to the left air temperature actuator (2).

Tighten
Tighten the screws to 2 N.M (18 lb in).

3. Install the electrical connector (1) to the left air temperature actuator (2).
4. Install the I/P insulator panel.
5. Reprogram the air temperature actuator. Refer to Re-Calibrating Actuators. See: Heating and Air Conditioning > Component Tests and General Diagnostics

This happens when the right or left temperature blend door actuator goes out. This guide can show you how a typical system works and where the actuators are located. I have included diagrams for your car below.

Check out the diagrams (Below). Let us know what happens and please upload pictures or videos of the problem. Let me know what you find with this and we can go from there. Thanks

Check to see if the actuators on the HVAC are getting power. I will send a picture along to give you an idea where they are under the dash. Check out the diagrams (Below). Please let us know what happens.

On the split systems there are two actuators for temperature. The one for the passenger side is on top of the HVAC housing. To reach it you need to remove the dash and the actuator is the first item on top of the case. However, you might wish to try doing a
re-initialization of the actuators first.
That involves turning the key off, then removing the HVAC/ECAS fuse (10 amp in the underhood fuse block) for 20 seconds at least. Now put the fuse back in and start the truck. The actuators will self calibrate in under a minute. Try the heat control. If it works great, if not then you need to replace the actuator.

On the fan speed, which speed do you have? Is this the manual system or the automatic version?

Try pulling HVAC fuse inside truck for sixty seconds with key on. Leave key on and reinstall then start truck it may reset the actuator. It is mode door one that is sending air to windshield. That is on left hand side by gas pedal it may be cable operated. The other actuator is on top of HVAC unit it says to pull the dash to reach it but if you have small hands you may be able to get it from glove box. See picture. The actuators are from $35.00 to $130.00 depending on your system. You need to know if it is a D07 or not.
