Blower is not running ? Or is ?if the blower fans not working check fuses or replace motor , if your heat cycles and your blower blows cool air , its likely a heater core issue

1999 VW Passat AC/heat doesn't work? The belt broke this summer? I was told should still blow heat even if no belt?


If you are talking about the belt for the ac compressor, yes the heater should still work.
If the blower is not working, you will need to have the blower motor checked for voltage and ground.

Blower on heat/a not working


So it works with a/c but doesn/t work with heat. Is that what your saying?
Or it blows cold air on heat selection?

If it blows but only blows cold air on heat selection
check out the following items:
temperature selector switch
blend door actuator and motor.



Here are a list of items to check out or have a shop inspect if it doesn't blow anything at all.
a) on/off switch
b) relay
c wiring
d) resistors
e) blower motor
