I have a 1999 Dodge Ram pickup truck. The heater is not functioning properly. The heater core appears to be intact (no leaks) and is actually quite hot. Luke-warm air does blow from the floor and defroster vents. However, the center vents do not blow air at all, even when set (via the dash control unit) to exclusively blow from those vents. Any suggestions?

Vent controller switch not working on a 1997 Monte Carlo.You can switch to all setting but still blows out thru defrost and floor only.A/C compressor engages but still blows thru defrost also will not blow heat or cool air thru vents.I changed the controller assembly and does the same thing.Is there a relay and fuse for the assembly?

Just got heater core replaced and now have no heat from heater or defrost. Fans work, just don't blow anything beyond "cool". The heat in my car is coming and going. I want to know how to fix this? How do I change my thermostat and where is it located? It only blows some hot air when I have it turned on to the vent button but when I have it on defrost or the floor it blows cold air. Can someone help me please?
It sounds like when they replaced your heater core, that they didn't properly hook up the blend door contros at the control panel. I would take it back to the repair shop that did the work and have them go back over things again just to make sure. ... 1992 Mercury Cougar
I have a 2002 chevy trailblazer. Yesterday my heater worked fine today I had the battery replaced and now I notice when the heater is turned on it is only blowing heat on the drivers side. Defrost floor and dash vents. But on the passenger side all of these vents are blowing cold air. Yes I have the manual climate controll levers slid into the up position. How can i solve this problem and might it have anything to do with the battery change? Doug
