on 01 1500 havin some trouble with the heater. it sounds like its going full blast but doesnt blow air like its on full blast. the air it does put out is warm though. just wonderin if anyone else has seen this before.

 

mine had the same problem and it ended up being the in cabin air filter which is probably clogged, it is located on the passenger side below the left side of the glove dept. it's one screw and pull it out. you can clean it or replace it but it might slove it.

 

Yeah cabin filters. $16 for new ones. There are 2 of them. I just left mine out cuz replacing them all the time cost some money. Over here where I live its pretty dusty.
