Heelo all, I have a 1992 accord ex that I just purchased. The car has 185k miles. The problem I am having is the car has no heat, even after warm up. The heater core is open because I can blow air through it. I think it may be the water pump. Any help would be greatly appreciated. The thermostat has been replaced.

 

First things first... check the coolant level.

 

Coolant level is full, and with no air in the system. Thanks for the reply.

 

Have you checked the heater valve? If it doesn't open, hot coolant won't flow through the heater core.

 

Yes, the valve is open.
