Why does my truck heat turn cold unless its sitting still my coolant is full new thermostat and system has been flushed?
Try backflushing the heater core. You have two heater hoses going into the firewall - after running, one should be hot to the touch, and one should not. The one that's hot to the touch will be the inlet... when you backflush it, you'll use it as the outlet. Disconnect the heater hoses, keep the ends elevated, put in some radiator flush or CLR, and let it sit for about 15 minutes. Then, using the outlet hose as the inlet and vice versa, you can either flush it out with pressurized air or pressurized water.
