Jim-

I faced the same problem. You either have to crack the heater box
open in the van and undo the wired at the motor, discount the wire at
the heater switch or cut it. I tried to release it from the switch
but couldn't easily do it and cut the wire. My reasoning was I'd
rather use a butt connecter then trash the connecter or the plug.

The wires come from a connector plugged into the back of the heater fan
switch. There is also a brown ground wire running over to the main
ground stars where it can be unplugged. The power wire from the fuse
panel to the fan switch connector can be released from the connector
shell with a jewelers flat blade screwdriver.
