Should have written, Patient Man, I get too frustrated with these monsters. A while back, I had an ac issue. I posted the symptons on the F150 site. I got a Ford Factory Technician reply and he told me what was required, basically 8 hours to remove the dash and get to the unit and replace a plastic flap...after obtaining schematics, I was planning to do the repair one weekend. A friend borrowed the truck, brought it back, "Oh, I fixed the broken ac dash switch for ya" "the old one was cracked and didnt allow you to turn down the temp..."
The point is, 8 hours to remove the dash and get to the part, tells me, that the dash is going to take you a bit of time to remove...
Good Luck
