I am happy to report that I have successfully replaced the Fresh Air/Recirc door actuator that is located on the blower box-and have done so without having to remove the blower box. I did it by taking out the glove box and attacking it from the back. It took several days, LOTS of patience and some band-aids, but it is done. THE most difficult part -BY FAR- is to remove and then replace the screw that sits on the actuator arm, connecting it to the fresh air/recirc door operating arm. It took 5 hours to get it off, then 4 more to get it back on. But it is now all buttoned up and tomorrow I'll run through a complete system test. Right now, I'm tired and bloody; the entire area where you have to work is VERY tight and has sharp metal surrounding it, thereby limiting your range of movement-and the type of tool you can use to loosen/tighten the fasteners.
