Trunk Wiring problems of the 2002 Volkswagen Jetta

Known melting fuse box on top of battery. From schematics, appears s180 fuse (coolant fan) as predominant point of failure. Issue has been reported (via web) across numerous models and years. Called vw for fix; as techs appear void of a general consensus to problem/fix. Unfortunately, vw refuses to acknowledge and/or provide solution to customer(s). Refers me to dealer, which is over an hour away. Just need info to order repair kit and restore vehicle integrity/safety. Concerned as this may be a potential fire hazard; due to the volume of heat generated by wiring within internal compartment. In turn, I understand the age of the vehicle is outside the normal warranty period. As stated, just want an answer to repair; however, vw customer care rep commented I should reporting this issue in hopes to draw additional attention of other owners and, eventually, the NHTSA to get vw to respond to customers questions.

Purchased used 2002 vw Jetta 1. 8 turbo (5 speed) with 34,000 miles still under warranty. Taken to dealership for blown fuses (cigarette lighter), trunk latch, center console, and transmission repairs. Fuse problem was ongoing. Within a few months, a local mechanic installed a small boost gauge on the dash, which was wired into a 10 amp fuse. Within five days, the car was being backed out of the driveway when smoke began pouring from all the dash vents. The wire harness, fuse block, and controller components located behind the dash were destroyed by fire. Vw of America prepared to send investigators to nm, but when they discovered gauge wiring may have contributed, they did not investigate. Have read of other electrical fires behind instrument panel, dash, since this time. Our son was driving the car at the time of the fire, but was able to get out.
