For those with blend door issues:
Just found this site, you can get a WJ blend door repair kit # K6855685AB, from Mopar/Chrysler/Fiat and this site has 8 pdf. files giving step by step instructions. Looks quite easy to do whether you know how to work on things or not.
I've seen a lot of post about this issue and this should be a lot of help.
