to perform the DIY. Took my quite a while to get to the point that the mixer door was out of the car, but I got there. Re-foamed and taped up the door. Putting it back in was very difficult for me. To get the little bushings under the door axis caps on both top and bottom was super tricky. After some cursing and blood, I thought I had every thing back together in order.
Alas, when I started the car up and brought it up to temp for the all-important test of my not too handiwork.......it blew cold air
Not even luke warm like before. I could hear the servo motor moving (or trying to move?) the door when I changed the temp on the dash control unit. Any ideas before I admit final defeat and take her to the dealer?
I did take some pics that I hope can be of help to others.
