Rear Air Problem
2003 Ford Expedition 5.4l
My rear air has two separate problems.

1) It makes a clicking noise whenever it's on.
2) it only blows when on A/C, if I switch it to heat, the air stops blowing.

Help.

1. Is a blend door actuator. You've got a choice of two back there. One is floor to ceiling, one is hot to cold. You should be able to adjust either variable and hear the noise change to tell you which it is.

seems to be hot to cold.... I found some videos on YouTube. I'm thinking it's the one on the back right panel.

There are two on the back right panel. The easier of the two is the floor to ceiling one, you've got the harder one to do. Go to my albums, there are some pictures showing where it is.

Click on my name, then public profile from the drop down. Albums are on the right hand side of the page under my icon picture. The actuator you are looking for is on the side of the wheel well behind the vertical side wall.

Had to use a desktop! But I saw it. Thank you. I will start looking up how to remove that side panel.

If you have small hands and some dexterity you can do it through a combination of removing the cup holder and the change tray on the top of the quarter trim.

I do have small hands, but I'd like to flush that rear heater core while I'm working back there anyway.
