Front defrost not blowing from vents

Bad servo motor

 

Where is it? How much does it cost? How hard is it to replace?

Thanks...

 

Not very expensive to buy and not very hard to remove and install, but definitely tedious to get access to.

Because of the tedium, it might be advantageous to be more sure of what the problem is before pulling parts out.

Although difficult to reach, the air-outlet servo might be possible to watch in action, after removing the glove box, which is easy. A phone camera or inspection camera might get an even better view.

The Repair Manual (more info) describes how to ask the HVAC system for diagnostic codes. If you have no scan tool, you can simply hold down AUTO and FRESH/RECIRC together, while powering the car on. Any two-digit diagnostic codes will be shown at the left of the HVAC control display. That method also enters an actuator-test mode, also described in the manual, where you can command the actuator to different positions and see what it does.

If you have a laptop with Techstream, you can do the same thing, and even see what target "pulse" position is chosen for the actuator, and whether it reaches that "pulse" position or gets stuck at some other position.

The Gen 3 actuator (described more in this post) reports its position through electrical pulses, which are counted by an IC built into the servo wiring harness. That's a change from the way the Gen 1 and Gen 2 actuators worked.
