Lumina temp problems

Hi everyone...

I have a 97 Chevy Lumina. When I drive I have hot air and when I stop it goes cold?!? Can it be the heater core or thermostat? Any help would be greatly appreciated.

what does the temp gage do? might be thermostat stuck open, worn water pump, cooling fan coming on too early, or a slight blockage in the heater core. i'd have the cooling system flushed and a new thermostat installed, even if this doesn't fix the problem it's good preventitive maintenance.

When the car is idling the temp gauge goes up, no heat from vents, when I start to accelerate, gauge goes to middle and heat starts pouring out of vents. I am going to change the thermostat first, but I am sure there is more to it then that...

maybe heater core is clogged

check your coolant level. the no heat from vents would occur if you had no water flowing thru your heater core also.
