2000 Pontiac Montana Heater only works at high rpms
Heater problem
2000 Pontiac Montana 6 cyl Front Wheel Drive Automatic 170000 miles
At idle the heater blows cold. Go down the road or just raise the rpms and the heater blows warm. Does anyone know what the little pump is for that is in line with the heater hoses and when it should be on??

Post a pic regarding the pump
Check your antifreeze level, sounds like it is low or there is a restriction in the heater core.
If the fluid is low is will not circulate into the heater core until the water pump spins faster from the raised rpm..
