Vw polo 2005 1.6 trend not getting hot air in the cabin always blowing cold air no mater how long i have been driving.


the way any motor vehicles interior heater works is by allowing water from the engines cooling system to circulate through a mush smaller radiator located behind the dashboard and the fan blows air through the radiator allowing the warm water to heat the air so when you select warm or cold via the interior controls a valve fitted in line of the water pipes that is linking the engine bay radiator to the interior one allows water to flow which makes me believe that valve is not functioning

Vw polo overheats


a cold hose indicates an air lock in the cooling system, if this is the case have it bled to remove the air lock. it could also be combustion gases leaking into your cooling system indicating a possible head gasket failure, your anti freeze can be tested for traces of combustion gases.

Screen washers will not work on my vw polo 61reg fuse has gone. where is the screen wash fuse in a vw polo 61 reg?


I really doubt the problem is a fuse. More likely the pump is defective or plugged or the washer switch is defective, use a test light and problem the connector to see if it lights when the washer is activated by the switch. If it was a fuse it will just blow again. Fuses blow for reason that is a shorted circuit.

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.

Heater only blows hot (well, warm) on full speed of fan


Replace the temp control on this car, it should be electrical control not cables.

Hi, Try turning on blower, set to warmest setting.

If the blower is blowing cold air, the problem could be Water Pump needs replacing!
