Notification K17
I took mine in today, and now the air only blows on the floor. I didn't have time to wait for the corrected repair. It's amazing, I take it in with nothing wrong and bring it home broken. I think it's supposed to work the other way, right? The service manager says, "Oh sorry, when can you bring it back?" I wish there were another dealer near me, but the next closest one is over 60 miles away. Just a heads up, make sure it works correctly before driving away.

I think the problem seems to be with the computer. There is no heat, no A/C, the only control that works is for the fan speed. Also, the dimmer switch no longer controls the lights for the heat control *****. I guess I'll just have to wait to get it back to the dealer so they can reset the computer. Do you guys think if I disconnect the battery it would do any good? Would that possibly reset the computer?

Last week i got in my truck and turned the key on and heard a series of POPS coming from inside the dash. I took it to the dealer and they performed the K17 recall and replaced the defrost door actuator. They also perfoormed TSB 18-019-09 and TSB 0801809 and everything is fine now....

I haven't noticed a decrease in the air flow on mine... Course, I rarely even have mine on considering that the seats and the steering wheel is enough heat for me. LOL
Did they check to make sure that the blend doors on yours were not broken?

Shortly after having this recall performed, mine was fixed but soon started having issues. The temperature adjustment was unreliable - the temperature had a mind of its own. Then it became stuck on cold, no heat whatsoever. At the same time, it started periodically making a popping noise coming from behind the dash. So I removed the lower glove box door and by feeling for the vibration, found the offending solenoid. I removed it and took it apart to find the plastic gears inside stripped. It is the actuator closest to the 110 volt outlet. The part number is AA-113800-3041. POS plastic gears. So I rotated the gears by hand so they would mesh, turned the blend door to full hot air, reinstalled and unplugged the connector. Now I have heat (only).
As I understand it, the havc controller has no actuator position information other than when you turn the temp control, when the motor hits the stop, the current goes way up. Well it drives the actuator to the stops and relies on the POS plastic gears (if they are intact) binding to tell it when it is at one temp extreme or another, and your temp adjustment moves it incrementally away from there. Poor design.
