Hello everyone! Need some help with the location and possible procedure to replace the heater blend door--the one that diverts heat to the floor of the car. All other vents work great, heat works great, heater controls all light up appropriately. The heater controls SHOW that air is being diverted to the floor (green arrow) but...nope...no heat down there.

Code reader confirm that actuator is at fault.

Calibration with a scanner did not solve the problem.

I *think* this actuator is called motor #4. I'd like to know where it is and how much of a pain it might be to replace it. Any ideas? I checked on All Data and they don't tell you diddley about it--nothing on YouTube either...sigh.

Anyone ever dealt with this? I imagine S40 owners would have about the same problem/location.

Mine is a 2008 Version 1.0 T5, manual transmission.

Thank you all in advance.
