I have a Dodge 2002 - 1500 SLT truck
The heater will not heat when warming up truck. I can let truck warm up for 30 mins. And it never gets warm. But when driving it will start to heat. Can you please tell me what is wrong. Thanks so much

When letting truck heat up feal the heater core hoses leading into the cab from the engine compartment? Are they warm? If not then the thermostat could be sticking a little or maybe even a air bubble is in your coolant system so that should be bled. If it is warm suspect that its your heater door is not functioning properly due to bad vaccum or faulty selectors.
