out of all the work ive done on the truck, the AC system is the easiest. If you do more research there is a few threads that answers all your questions. The only thing you need the AC shop for is to drain and refill.
How long did it take you to change / get to the servo motor?
Have you checked the FSM that is specifically for diagnosing the AC? Its a separate document.
The 80 to me need some sort of moulding treatment to break up the run of the panels.
You have my vote, please put me down on the buyer's list pending cost. Thanks.
Please let me know what info I should provide.
