the heater fan resister,it is or should be on inside or on outside heater box.
The stage 1 relay has blown! it is located behind the glovebox door above the heater blower. # find it # pull it out # replace it job done:-)
The blower motor resistor is bad.
Probably the blower motor speed resistor is partially burned out.
it may be the switch have it checked out
The usual cause is a failed blower motor resistor.
most vehicles have one circuit(and one fuse) for the first 3 fan speeds and a separate circuit and fuse for the highest speed.AnswerCHECK THE BLOWER MOTOR RESISTOR
Get a new switch.
In a Mark 3 Golf, the heater blower is typically located under the dashboard on the passenger side of the vehicle. It is housed within the heater box, which can be accessed by removing the lower dashboard panel. If you're experiencing issues with the blower, checking the fuse and the connections can be a good first step before considering replacement.
