[T3] fresh air fan switch

[Daniel K. Du Vall]

Jim,
	Have you ever rebuilt the fan on a 72 or such?
Mine squeals till it warms up and I have been thinking of pulling it and seeing what I can do.

I'm afraid that's not a switch problem. There's a resistor built into 
the '73 fan and those have a rather poor failure rate. Mine is dead 
right now, too. It's a 1 Ohm power resistor, but it's quite hard to 
get to. VW actually sold them as a replacement part, but the better 
option would be to replace the whole fan and housing with one from an 
earlier car. Those use a different motor that has a low speed winding 
and don't use the resistor.
