00 Accord Heater Cold Air

[lbuzogany]

My wife's Accord heater never really puts out hot air, eventhough the engine is warmed up. While driving the heater actually puts out cold sometimes, then switches back to warm. Is this a vacum problem, or just the climate controls?

might be your heater core

After the car heats up. feel the inlet and outlet hose to the heater. They should both be hot. If not, check the heater valve.

Thanks for your responses, I'll check the heater core and valve...
