AC 50 amp fuse is in the driver side D pillar (the rear most
pillar) under the plastic. In fact there are a few relays
and 2 20 amp fuses which fuse motors to ground (according to
the bentley) in there as well. I had the fan die when I picked
up my van from the PO (it had worked on the test drive). Turned
out one of the wires (single connector) had come off the back
of the fuse box. Was a PITA to track down. I had dropped the
whole AC tunnel tracing the circuit backwards (started on the
wrong end I know)....
