Sadly, I'm more of one than I am a mechanic!
I'm here because I got my Google on. I have a heat problem. As in there isn't any on the driver side. Plenty on the passenger. Fans blowing fine on both sides. Anybody in here have an idea?
Welcome to the Diesel Forums! Not sure but you must have a split system, sounds like one of the duct doors may not be acting right and in the wrong position. I really don't have a clue on your system so maybe someone can shed some light if it's close.
Welcome to Diesel Forums
I'm with Joe
I think your left duct hasn't opened cause the damper hasn't opened
I'm not real sure how the Classics work, but I'm pretty sure the the duct doors work with vacuum.
The damper actuator may have a vacuum leak or the line may have a leak or fell off.
Hope this helps
Good luck and keep us updated on your progress
