freezing
 

Hey there , i have a 94 tt and the cockpit heater aint workin .
Its blowin cold air only ,its been suggested that it could be the heater valve , where is this or is it likely to be anything else .
The temperature is remaining constant and the regulator behind the glove compartment is working fine ?

i do not know if this is the same problem as with the mkiii heater switch but you might want to look at my web page and decide if you want to try to by-pass the vacuum line on yours
