Question about 2007 Dodge Ram 2500

2 Answers

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

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.

SOURCE: 2007 Dodge Ram 1500, blower motor stopped working

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!

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.

Why wont my heat in my1997 ford f150 work


check coolant level and temperature of the heater hoses after the engine is at operating temp. the heater hoses should be the same temperature if not then the heater core is plugged and needs replacing. if the hoses feel the same temperature but not heat you may need to replace the thermostat. I am guessing the blower motor is functioning to blow air over the heater and into the cab.

Heater runs but does not heat


If it is blowing air at different speeds inside the car, I think you are saying the blower works fine, but blows no heat.
If it is running different speeds but is not blowing inside the car, you probably have a plastic flap inside the heater assembly inside the car that is not opening, not allowing the air to come in.
That might likely be a vacuum issue, or maybe a mechanical one. (whatever is supposed to open the flap)

If the flap is working and you are getting different amounts of air inside the car according to the speed of the blower fan setting you have selected, go to the engine temperature.
Is the radiator getting hot?
Have you a temperature gauge to tell if the engine is hot?
If not, you will need to warm up the engine, and then determine if there is hot water in the radiator.
If you pull off the cap to see, it could blow up on your face, so you will need to find someone who can help you with this.
If the radiator is hot after about 10-15 minutes of the motor running, you are perhaps not getting hot water to the heater.
You would need to check the temperature control to see if it is working. This is often a mechanical switch located near the firewall of the Jeep under the hood. Usually it is the size of a small fist, and has a heater hose running into and out of it, and has a wire attached to the top.
It might have a wire to it that should move when you select hot or cold inside the jeep at the control panel. Sometimes the control wire will rust or break.. The heater hoses should be hot if the hot water is running through them.
If your radiator is low on coolant, often the heater inside the car will not work.

Heater blows cold air


Air 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.

Heater does not blow hot or even warm air


This is not a heater valve problem, for one thing there isn't any such part in the model. The problem is a defective air temperature control blend door inside the air ducting.

Heater is blowing cold air.


Start with checking coolant level, if low it will cause a no heat problem. If radiator coolant level is correct you might have a temperature door problem. The temerature door is located inside the HVAC module and is controlled by the temperature control knob on the dash board. The electric motor that moves the temp door may have failed.

Heater blows cold air when i turn it on blows a little warm air then it is cold


It sounds like you may be leaking coolant and are low on coolant. Low or no heat is a sign of the coolant being low. Vehicle can leak coolant from multiple locations. Top off the coolant level and see if the heat returns or gets better and get back to me.

Other causes could be a clogged heater core, Temperature door motor/door not moving, cylinder head gaskets, engine block, thermostat.
