Group,

The problem with you van maybe a resistor behind your driver's
headlight.  Remove the grill.  Then the four screws holding the light
bracket.  On the right you'll see a green resistor, approximately 5
watts, hooked to a small wiring harness.  If the resistor is burnt or
cracked, it is bad.  It is a VW part.  I had to replace mine about 3
weeks ago for the third time.  The resistor sells for about $26.00.  The
VW part number is 251 971 284H.

This resistor controls the fan speed for cooling the engine.
