OK, its a Passat. and it isn't even mine.
But a friend, who's a pretty fair mechanic, just bought a 2001 Passat
for his son. It should be very similar to B5 A4s and S4s in this
regard, I assume.
One problem is that the heat doesn't work - it blows stone cold air
(I'm told). They know the history of the car, and the owner says it
was working normally one day, and totally gone the next. We suspect a
mixture (cold/warm air) stepper motor died or a connection to it has
a problem. But i've not heard many complaints about this.
Any wisdom? Common problems? Things to check? Warnings?
