99% chance it is the blower resister located behind glove box. Squeeze glove box in and pull out.
The resistor is right behind it, dealer part cost less then $20.
Dodge has had this problem for over ten years and until recently did nothing. Now they combine fuse with resistor, suppose that will correct it?

Sounds like the air "blend" door might be inoperable. This door opens and closes a specified amount to regulate the amount of either cooled or heated air, as requested by the climate control unit. If the door is continually in the position which is bypassing the heater core (cold setting), the air will not get warm regardless of the condition/operation of the heater core. I'd suggest having this component checked.

check the coolant level, I had the same problem low coolant level.....no hot water to the the heater coil.

Replace the bad radiator hose first. Â Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator. Â Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it. Â Fourth- Check for leaks by looking for the colored dye. Â If it's not the radiator hose, then could possibly be a pin hole in your radiator. Â Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

Have you checked the coolant level? What you describe is exactly what happens if the coolant level is low. When stopped at idle, hot coolant is not circulating through the heater core, so no heat. As the engine increases in rpm's when you pull away from the light, the water pump is spinning quicker, and some coolant is making it to the heater core. So check the level, and if it is low, keep an eye on it to see if it drops again. That of course indicates a leak somewhere. Get it fixed, as overheating the engine leads to costly repairs and worse case a new engine. Let me know how you make out with this.
