SOURCE: 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.

chances are if you system was serviced by modern equipment then they would have pulled a vacuum before recharging .. that would eliminate moisture in the system .. the evaporator is inside your heater box .. you cant see it .. the condenser is the radiator like device in front of your engine cooling radiator ..

if the system is changed properly and still does not work or works intermittantly . then there is a good chance that the air conditioner clutch electronic module is bad .. thats a relay like device located on the drivers side behind the dash .. you have to snap off the dash side panel .. its normally hidden by the door .. inside that is the fuse panel and behind that is the relays/electronic modules .. the one that operates the air conditioner clutch is marked 384 .. there are other possibilities depending on your a more precise description of the problem ..

there is a fan resistor which controls the speed of the fan,which is probably burnt out,should be located near the fan motor,behind glove box.

SOURCE: how to open the fuse box in my VW Golf Plus

Usually a small flat screw driver wedged under the plastic covers should help you pry it open.
FYI If a fuse blew it went for a reason. ( old age on a 3yrs old car isn't a reason).
