Scott,

Your van has two fan speeds.  Does the High fan speed work?  This should
turn on when the temp needle is at 3/4 to 4/5.

Assuming the thermoswitch is ok, since it's new:

You should be able to short the connectors on the wiring harness to the
thermoswitch.  There are three prongs one of which is the fan motor
input voltage.  If you short the other two to the fan motor, you should
be able to cause the fan to turn on.  If there is no high or low fan,
I'd suspect either the fan motor, relay or fuse.  If there is no low,
try the ballast resistor.

If you need to check the ballast resistor, it's behind the driver side
headlight.  It's a big ceramic resistor that is used for the low speed
fan.

If this is ok (i.e. has resistance in range), check the fan relay(s) and
fuses under the dash.

Wade
