I'm preparing to replace my fresh air actuator. Good tip re. don't remove the air bag.

Glad to hear you got that Actuator fixed. View attachment 277663

A question... The fresh-air actuator is a two position type. If it comes with the position centered how do you install it? E.g. move the door to the center and then slide the actuator into position?

When replacing the actuator be careful which one you get. Some have 3 pins and some have 5 pins. I was not careful enough and ordered a 3 pin type for the recirculation door and it didn't work. Bought a correct one from the dealer ($275) and installed it. It worked with a two way scanner so I'm putting things back together later today. I ended up cutting the duct to get at it. Will tape it up on reassembly. I hope this solves the issue of recirculation door not working. We'll see.

Update. It looked liked getting the correct replacement actuator worked. Imagine that. I put things back together and didn't install the dash cover incase I need to go back in there. Taping the cut duct section back in seemed to go okay - I used electrical tape and aluminum tape. All seems to be working. I replaced the light sensor and looking at a way to easily test it before I put the cover back on. When I plugged the air bag module back in the B code went away so I assume it will be working correctly.
