I"ve bought 2 new actuators and plug them in, when I turned the heat or air on manually the switch on the actuator didn"t move. Any ideas?

CHECK THE MODE ACTUATOR ON DRIVER'S SIDE

There is blend door in vent channels under the dash of the vehicle. It blends warm and cool air in the vents depending on the temperature setting. The Blend Door is controlled by a motor called an actuator that gets its signals from the setting on the dash. When the actuator fails the blend door can't move. If it stops on hot you always get hot air.
3 possibilitys
1. Blend Door stuck.
2. Temperature control not sending signal to actuator.
3. Actuator motor gone bad.

Of the 3 possibilities the actuator motor is the most common and the easiest to fix. The part is $40-90. I don't know exactly where actuator is on the Pilot. My GMC you remove the plastic trim below the dash and its just to the left of the glove box near the 'hump'. Perhaps the part store can tell you or someone else will offer the exact location.

Once you remove the actuator you can plug it back in to the wire clip and move the temperature knob and see if it moves. When you get the new one plug it in and make sure it turns before bolting it in.

To clarify a bit. The heater is never technically turned off. The blend door determines how much it goes thru the vents.

go back to the dealer and get the user manual and the service and warranty book ( new car)
or is it an old car that is new to you
in which sweet talk a dealer salesman to show you what operates what

your gonna have to remove actuator and manually move door to see it that helps.
did you get right actuator? there are 2, 1 manual and 1 auto climate controls. maybe reduce file size or change format? Take a look

Even though you have a manual HVAC system it still has the capability to set an store DTC'S - diagnostic trouble code's .
DTC B0413 02: Temperature Control 1 Feedback Circuit Short to Ground (CJ3)
DTC B0413 05: Temperature Control 1 Feedback Circuit Short to Battery or Open (CJ3)
DTC B0413 61: Temperature Control 1 Feedback Circuit Actuator Stuck Open (CJ3)
DTC B0423 02: Temperature Control 2 Feedback Circuit Short to Ground (CJ3+C67)
DTC B0423 05: Temperature Control 2 Feedback Circuit Short to Battery or Open (CJ3+C67)
DTC B0423 61: Temperature Control 2 Circuit Actuator Stuck (CJ3+C67)

Did you have Actuator Recalibration done after replacing the actuator or control module ?
Your best bet ,take your vehicle to a qualified repair shop .
Preferred Method (w/ Scan Tool)
Clear all DTCs.
Place the ignition switch in the OFF position.
Install the HVAC actuator.
Connect all previously disconnected components.
Start the vehicle.
With the scan tool, initiate the Motor Re-calibration feature of the Heating and Air Conditioning Special Functions menu.
Verify that no DTCs have set as current DTCs.

It is air coming out of th defroster? On th windsheld? Th switch that control d vents, is digital or manual? It could be disconected from th vents inside th dash not leting th air come trought. Th blower in th pasenger side under glovebox work?

make and model ?????????
some chevrolet product have cabin air filter in plenum box
may need to get replaced may be pluged up

Probably the blend door not actuating. I do not have the manual on where your door actuator is. It's usually right of center under the dash. Look under there and see if you can see anything trying to move when you change the temperature setting. Also, if you hear a clicking noise, that would be the actuator stripping it's gears. If youy can find the actuator, take it off and see if you can manually rotate the door hinge. If yes, replace the actuator. If not, you will have to remove the heater box to find out why the door is jammed. The actuator looks like this:

Possibly.. the actuators which operate the doors actually have a position signal for reference, but the actual motors inside the actuators dont realize there is a limit and overshoot their limits causing the fine wires inside to rip apart rendering the actuator scrap but this happens when actuators are still plugged in to the connector while being taken off the heater door, and they can and will still move with the key in the off position if the actuator thinks it not in the proper position..thats how they work anyway.hope you had them unplugged untill the last, then this would'nt happen....hope this explaination helped

you can have two things wrong with your car 1 a/c control head is bad. 2. temp blend door actuator is bad. change actuator first. make sure you install it before you plug the connector.
