One problem related to dash wiring has been reported for the 1997 Ford F-250. The most recently reported issues are listed below.
I was driving along on rt 295 during a rain storm and my windshield wipers stopped working along with other electrical componets in my truck. I drive a 97 Ford f250 4x4 XLT. Luckily I was not injured. I took my truck to be fixed where I was told that I needed to replace my gem module and fuse box. I thought that was odd. The mechanic said that the windshields on the model of my truck is known to leak and damage those componets. I could of got into a serious accident that day, resulting in death of me or other people on the road.
