Question about 2007 Dodge Ram 2500
The heater motor is working fine but the temperature that it blows out will only get up to a very low 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.

Have you checked the heating duct, maybe its clogged or off alignment. Does the A/C seem to be working? If not maybe there is a common link between the two.

If the ground is good I would take a careful look at the light socket itself. There may be corrosion inside or on the power wire where it goes into the socket or it may just be making poor contact.
You can get a replacement one at any auto parts store. The last one I got was about $10. Get some heat shrink tube to cover your splices, it does a much better job of sealing the splice than tape. Hope this helps.

The Low Pressure Side connector will be smaller than the High Pressure
Side connector so the refill hose will fit properly only on the Low

Hi, On the passenger side, up under the dash is your blower motor. Have the key on and the fan switch on and bump the motor with you hand. It is the unit with the quick disconnect wire going to it on the right side closet to the wheel well.I took mine out today and cleaned it with spray cleaner for electric motors (NON-FLAMMABLE) and put it back in. There are only three 8 mm bolts holding it in place. I have a new one on order from PEPBOYS($51.00)but for now it's working just fine!

SOURCE: 2007 Dodge 2500 5.9 diesel.
Working same problem today on my 2006 Mega Cab Diesel. 2 possibilities. Either the compressor clutch coil is going bad ( totally integrated power module tries to engage it a couple of times, senses the coil resistance is wrong and shuts down) or the TIPM (Total Integrated Power Module) is bad. I'm leaning toward clutch on compressor but still have testing to do to isolate. Could be both, but I doubt it. New TIPM is about $900 it appears from what I read. New compressor is cheaper. May be able to replace just the clutch coil for even less but reading mixed results. Good luck.

Temperature Control Blend Door Failure No Heat
In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.
