Ok so i bought this durango i love it its clean its awesome and powerful anywho I noticed a hissing noise and its very annoying at times and it kinda comes and goes (or i just dont notice it some times) and i have not really been able to pin point as to what causes it to start doing it at all its pretty random.. it seems as if its comeing from the passenger side in the cab? Any suggestions as to what it could be? Also on another note my hvac nob (controls where the air comes out at ( defrost, feet, front ext.)) Only works on front blowing at me no matter the position it is in. I have removed the whole unit and it all seems fine also decided to dismatle it and see whats inside lol bad idea dont do that haha ive kinda ran over some lines under steering column (yellow and blue) but thats as far as ive went.. no time or really want to do more but i need it fixed cuz it takes like 20 mins to defog windsheild when its blowing in opposite direction lol but i assume this hissing noise has to do with that not working any insight besides rip it apart and look for a possible culprite. Thanks 🙂 sorry for such long post lol
