I have a 1998 Ford Ranger Truck that the Heater Module Switch went bad. A/C works fine but it doesn't do much good as a defroster. The 12 volt Defroster that are sold are about 12 Watts and don't do anything, don't waste your money.
What I did was buy a 400/800 Peak Watt Inverter, an extension cord and a 200 Watt Lashko Heater, total cost $60. I place the heater on the dash on a rubber mat so it doesn't slide and turn on the heat and use the blower on low to distribute the heat. It dried up the moisture and defrosted my windshield just fine. My girl friend placed it on the floor boards and heated up the cab in no time. It was made to handle a office cubicle so a truck cab is no problem. There is no tip over switch on the heater so care must be used. It's only 200 Watts and the Inverter handled it with no problem. When I shut down, I shut off the Inverter so it doesn't drain my battery. Only problem it scrambles the AM radio signals but not FM, I can live with that when its C-O-L-D.

Check your blower motor resistor I think it's under your glove box.

I have a 2003 Dodge Ram 1500. The only thing that works is the blower. There is no heat, no AC and it won't switch from defrost.

I checked the fuses and tried two different control switches.

You may have a bad blender door actuator.

It may just be that your hose has come loose but I would suggest you take your Dodge to a local auto parts store (or maybe more than one?) (Auto Zone, NAPA, Advance Auto, Pep Boys) and ask them if they can help you locate the problem.

Many times there is someone that knows about a problem and can assist you - if not at one - go to the next. I have always had very good luck and good information from all of these stores.

I have a 2000 Dodge RAM van with a 3.9L. It was not warming up inside after driving 10 miles. Water temp was 190-200 degrees. I watched a YouTube video and learned that Dodge put the same size radiator on the different engine sizes therefore the small engines were over-cooling the coolant going to the heater core.

I blocked off the hose going into the water pump, installed a T on my radiator hose and ran the flow that was going to the water pump back thru the radiator hose. Instant Heat.

I have a 1999 Dodge Ram 2500. At first the heater/ac wouldn't blend. Now on top of that, the fan motor only works on high. And no matter what you select only the defroster works.

From what I have read , a dainty blend door actuator causes problems like this.

Hi,

I would go the the NHTSA site and check for recalls. You can input your vehicle identification number. This will give you a list of recalls. If your problem with your car is a recall, it will be able to be fixed for free.

So a car may be different than a truck, but when I had (still have unfortunately) issues with my 07 car, I was told that the cold weather (we had a terrible cold streak a few years ago and one morning when I turned the heat on I heard a loud SNAP and no longer got air from the bottom vent). He said that freeze caused the cable to the actuater (I am not sure I am spelling that right) to snap and that in my car's case, the parts are dirt cheap, but the labor is killer because they have to take apart the entire dashboard to fix it.

I trust my mechanic as he has cared previous cars and he has never steered (yes, pun intended) me wrong. He said the car can live for years without it, and if I didn't fix it it harms nothing.

The thrifty person I am, I didn't fix it (still have the car) and I learned to wear extra socks and fur lined boots in the Pittsburgh winters.

Hope your car is less expensive to fix than mine! Wishing you good thoughts for an easy fix!

Can you manually change the cold to heat under the dash on a 1997 Dodge Ram truck? The control knob on the dash does not seem to be moving anything, it moves way too freely. If I can change it from cold to hot under the dash please help me. I am freezing when I drive the truck.

Did you ever get an answer to this problem ? My 1500 blows only cold air - the temp knob doesn't switch from cold to hot air, just blows cold all the time.

I drive a '02 Ram 1500. I have no idea whats going on with my heat. The passenger side blows hot air, but it cools down. And the drive said blows cool air. I've replaced the heater core, and the thermostat twice. I also replaced the radiator.

I've gotten all the air out of the lines. I'm not sure if it's just a vent in the hvac unit. The top of the dash is missing and when I drive with my window open I can hear one of the vent doors open and close really loudly.

Not saying this will work, but I drove the front end of my Lincoln up on car ramps. I cracked open the reservoir cap and squeezed the upper hose to force air out of the system.

You will see air bubbles arise in the reservoir.Then close the cap tightly.

My daughter's truck heater won't stop working even when it is turned off. It is worse when the truck is accelerating, pressing on the gas pedal. We have tried putting it on the a/c side and it stills blows just as hot, and I mean really hot. My 1975 Dodge D100 has similar problems, while my Dodge Caravan just needs to be set to the a/c side to have it stop blowing hot at least. No one around our small town knows what we are talking about, meaning the mechanics.
