I replaced the Immobilizer last year with one from ECU Doctors and had them make me a spare. The Immobilizer is fine. Fuses C3 & D1 are OK.
FINISHED REPAIRED!!!!
Windows: Corroded Power Supply Wire in Left A-Pillar. Seized Motor in Right Door.
Locks: Replaced w/ ElCheapo $30 VW Latches from Amazon. Part# 3B1837016A -RIGHT DOOR, 3B1837015A - LEFT DOOR. This is ONLY for the '97 Model as it has different latches than other model years. Locks & sets Alarm w/ Key, unlocks deactivates alarm w/ Fob. That's good enough for now.
