I have a 04 laramie quad hemi etc... anyhow the passenger side a/c is not blowing cold, but the driver side is. Both sides work fine when its on defrost, so now i pretty much have to run it on recirc to get the passenger side to blow cold. So I assume it has to do with the temp toggle. Back around december I had a issue with the vents not switching and the great dodge dealership near me had to take apart the whole dash to fix it and broke some things so I had to bring it back for them to fix the stuff the broke in the dash, so I am assuming this is an issue from them but nothing i can do about it now anyway I suppose. Any ideas how i can fix this myself?

 

I forgot to add that the heat works just fine, just no cold air.

 

Sounds a lot like the classic blend door failure Chrysler is famous for.
