What 2003 Chevrolet Express 3500 owners say
Electrical system
Wire harness fire. Water got into the end of one of the connectors from the wire harness going into the trasmission. The result of the water getting into the transmission caused an electrical fire and caused a short in the transmission and engine wire harness, the final result was the wire harness was completely burned up. There was evidence of glueing the connectors years ago.I if the connectors are not sealed, it is possible for water to enter and short out connectors and other electrical components.
While driving vehicle, all electrical stopped, discovered that the ignition had turned off by itself and caused a loss of all power creating dangerous steering and stopping situation.. I was able to pull to the side of road and stopped vehicle. Took the truck to Chevrolet dealer in sarasota rt. 41 and bee ridge and was told it was not part of recall. This does not make sense, it has the same symptoms as the other defective vehicles maybe they don't want to increased their problems with another year and model. Please help, I am unable to drive my truck for work and am losing money and customers, as I am a general one man contractor. Please advise.
