Question about Cars & Trucks
You most likely have one of the following going on, a sticking or frozen air temperature control blend door or the motor that moves it is defective or in most cases both parts are the problem. Next you need to check and see if the heater core has flow, heat up the engine and touch the two small hoses going to the heater core at the firewall under the hood from the engine, one should be really hot and the other not so much, if this is the case the heater core is fine.

Heater blowing cold air until I get on the interstate, then it works; however, when I stop at lights it starts blowing cold air again. The temperature gauge will be in the middle but the car will still be cold until the car starts moving.
