I changed the actuator on the passenger side right behind the radio and the A/C wont blow through the front vents still. Can someone please help me out?

Good morning,

There are several actuators behind the dash.

The mode actuator requires the dash to be removed.

I attached a picture of the actuator. Is this the one you replaced?

The one right behind the radio is the one I got changed out and the guy that did it said they have another actuator on the driver side. Could that be the problem? I'll post a picture of the one I swapped out.

It sounds like he changed the blend door not the mode door.

I changed the actuator right behind the radio. Is there another one around that area too? Because it did not fix the problem or any other suggestions?

Good morning,

I answered this before for you and you never responded.

Did you replace the one that I attached with a picture? There are many. The dash has to be removed to gain access to the actuator.

I attached another picture for you. Is the one I circled the one you replaced?
