SOURCE: air only blows on floor with very little coming out the defrost or regular vents.

Hope you have the same set up, sure you do. You may have either crossed your vaccum lines or when you were putting your heater/ac box back together or you may of pinched the vents somewhat closed. Cycle through the different zones to ensure the vents are moving as your are selecting (defrost, floor, ect...) If you think the vaccum lines are correct then you may have a reassembly issue with the Heater/ac box. I had the same problem with my 2000 Dodge Ram 4x4. Use the KISS rule "keep it simple stupid" start with the vaccum lines and all your wiring to the motors, make sure everything is plugged in. Hopefully you'll find it there before going back into the box again.

SOURCE: Dodge Ram 1500...heater is blowing cold air, even

Take a flashlight and look up under dash from center console area, across to passenger side, for wiring harness, and/or hoses(small rubber) , they should lead you to it. Haven't had my head under one of those recently, and having a problem tracking you down a diagram for some reason, but it has to be there.

More than likely you have a bad climate control module (the knob critter thing). Unfortuneantely, you can't just buy one and install it, it has to be programmed on that year and model truck. I hate to say it, but sounds like a trip to the dealer. OR, you can find one at a slavage yard and try for the best. If the programming is the same, you might get lucky. the Stick

2007 dodge ram 1500 air only blows out defrost vents not front or floor


You have broken doors in your HVAC housing. This is a common problem with the older body style Rams. Does require moving the dash, but it's a fairly simple process.

I have a 2007 dodge 2500 diesel and the heater will only heat up to a very light heat.


Mode Door 1.
a.This door regulates air flow to either the dash vents or defrost/floor. If you have air flowing only through the vents with no defrost or floor, this door is failing. From our experience, this door is usually the first domino to fail. Not sure why, just is.
<!--[if !supportLists]-->4.Mode Door 2.
a.When mode door 1 is set to divert air away from the vents and into the second stage of the system, door #2 chooses whether air goes to the defrost vents to the windshield or out through the floor vents in the passenger and driver's side footwells. Failure is indicated by an inability to choose between defrost and floor.
b.This door turns out to be the most difficult to replace. In order to replace the door, the dash panel has to be removed. It's still better than the dealer fix because you don't have to evacuate the AC system, drain the radiator, and remove the plenum box. But it is more work than the other fixes. When this door breaks, it falls in the down position, blocking the floor vents and diverting all air through the defrost vents. From a safety standpoint, this is good since you'd most likely rather have a clear windshield than warm feet. We suspect that a large percentage of customers will just leave this door unrepaired. You will have heat through the dash vents and to the windshield, just nothing to the floor. It's inconvenient, but you'll have to make the determination if warm feet are worth the extra work to fix the door. An extra pair of socks is easier.

Heater blows out of defroster and floor vents no where else no matter where switch is set


Three things come to mind.
Defective door actuator.
Broken door.
Faulty switch.

Have someone operate the controls while you look up at the motors(at least three) blend, recirculation, and vent control.
observe the motors inaction you might be able to see the axles on them move. if all of them move, the door is at fault. Requiring dash and vent assy removal for repairs.
