You need to have the blend doors on the front heating / ac system looked at.. Sounds as if one is not working properly and not switching from hot to cold. It could be an electrical... vacuum... or the blend door actuator itself causing this problem. Some of these door motor/actuators are hard to get at and I would recommend having a pro look at it

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?

Your A/C sounds like it needs to be vacuumed
out and then recharged to factory specs. That
should solve the problem.

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

Did anyone find the answer for this?

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.
