Where is the driver's side Blend Door Actuator located?

Yep, this is common problem, here is a guide to help you with the repair and how to calibrate the actuator when the job completed.

Let us know if you need anything else.

The left side actuator is mounted on the underside of the HVAC. Remove the trim cover and you will see it. You may need to remove the center console to get to the actuator.

Thanks. That doesn't look as easy as I hoped but I appreciate it

It looks harder than it is. I have done it without pulling the center console but it's a tight fit. The cover is just a flimsy item that hides the molded plastic of the case (and provides a great place for dirt to hide) The actuator is just the screws and electrical plug.
