Heater was working off and on last week,was needed to add water to radiator. Could find where it was leaking, now this week heater blower won't come on... help me please

SOURCE: no hot air from heater, blower runs fine

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.

Since you state the 2 things you ruled out, that leaves only the water pump. Is the car running hot? The thermostat may be sticking as well... but im leaning toward the pump.

SOURCE: heater stopped working.. blower not working? 1999 ford taurus

sounds like the blower motor resistor which controls blower motor speed has a short and needs replaced.

did you run a compression check? if so and its good then you have a blockage in the water jacket
if not then you have a head gasket leaking

SOURCE: 2002 Mitsubishi Galant has water draining into the

the ac drain is more than likley stopped up, they tend to get clogged with debri not allowing the condensation from the evap. core to drain properly, thus allowing it to leak into the floorboard.

If it is fogging your windows, you have a leaking heater core. Dash removal is required to fix it.
