Have the heater core flushed. the heater core is a smaller radiator located in the air duct. open your hood, look at the firewall(wall closest to the seats) you should see two hoses a couple inches away from each other going to the radiator. unhook one, from the firewall connection, coolant will flow. then kink the hose so the coolant from the radiator doesnt drain. unhook the other hose from the firewall connection. now you have two pipes protruding from the firewall. get a hose and run it through one side and it'll come out the other. probably a lot of grime. now hook the hoses back up.
it could also be the switch

2001 VW Beetle heater not heating.


If both your heater hoses are hot, the heater core is circulating fluid. If only one is hot, and one is cool-then the core is plugged or has an air block, or a valve in the heater line is closed if that applies.
If the engine stays at normal operating temperature, doesn't overheat at all, there should not be a problem with the water pump.

The problem may be with the doors in the heater case not operating properly.

The heater blows hot air as long as the car is in motion when stopped or parked the heater only blows cold air


sounds like a circulation issue, can be one of three things, the heater core starting to plug, the thermostat hanging open, or the waterpump is getting weak. hope this helps

Mercury 2003 gand marquis heater does not blkow hot air the blower motor blows but cold air


One of 2 things could be happening. #1, the valve that allows coolant to circulate thru the heater core is not functioning. #2 the door that is actuated to allow cabin air to circulate around the heater core is not functioning properly. Possible causes, linkage to the valve, or actuator not working. Also a broken valve to the heater core. A vacuum leak, or faulty actuator would cause the door not to function. You can narrow down the problem somewhat by making sure that both heater hoses have hot coolant in them. You can do this by simply feeling the hoses. If they are both circulating hot coolant, then the problem is the misdirection of air flow. To repair this, the cause will have to be diagnosed, could be anything from your dash mounted controls to an issue with vacuum or the ductwork or the door or actuator. If not in the controls, the dash may have to come out. Good Luck, I hope this is helpful!

1986 VW Golf heater blows cold air


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.
if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.

I have changed the theromast twice and flushed the coolant system.The heater core is not leaking.. the blower is still blowing cool air.
