Here's some reading. You can check the codes to see what might be wrong:
Chances are it's the blend doors-$1000 Merry Christmas!
Chrysler should have made an admendment to the owner's manual and sent it to all the Limited owners directing them how to check for the broken blend door.
I realize it's a serious condition, but just annoys me to no end that they manufacture an inferior part(s) designed by an engineer(s) that should be fired, then they want to charge full price for parts and labor to correct their stupid mistake.
Or is it a mistake.........They'll be selling the parts, and if the dealer does the work, more money for them. JUust like the heated seats, etc.
