I've had the truck back from it's lastest trip to the shop... Before the air vents contols worked. Now, it only blows on the windshield (defrost position)... both hot & cold. I think this is a vacume line. I don't know where this runs but I bet it's damaged or fallen off.I'd really like to have my truck worked on & not have new problems when it comes back.Russ

The repair kit from heatertreater have arrived. It seems smple enough. A 9V battery pigtail is even provided to check the motor to confirm it's good before reinstalling. I'll let you know how it goes.However, we have a blizzard bearing down on us so I'm not going to be taking anything apart today.Russ

Let us know the procedure to reindex the motor when you get a chance.:thumbsup:
