I have 2003 ram 3500, in Florida so it just got cold, my control doesn]t make any noise or change vents when I turn it. don't know if its elect or vacume, but it used to make a clunk when it changed from one vent to another, cold feet. HELP
My 04 2500 4x4 has no heat on floorboard at all and lukewarm on drivers side dash vents. Passenger dash vents blow heat great. If you figure out your problem please let me know what you did to repair. Im here in Florida also and I do not like being cold. Thanks for any help anyone can give.
