Two problems related to wiring have been reported for the 1997 Chevrolet Venture. The most recently reported issues are listed below.
While driving on highway, I drove over debris (tree limb) on highway while passing semi at approx. 65 mph. When I ran over branch, all vehicle electrical and braking systems suddenly went off, resulting in loss of lights, power brakes, power steering, signals, and power from engine - a total shutdown. I wrestled van to side of road and had towed to town (while on xmas trip, travelling thru ok). After towed to dealer (closed, at night), I checked under van to find a male and female plug for wiring harness disconnected and hangling down midway from front to rear on drivers side. I plugged two back together and van worked perfectly with no further problems. Altho there were no accidents, injuries, if my wife or daughter had been driving, they probably would not have been able to stay in control, pull van to side of road. I beleive that connector plug of this crucial harness should be better protected from unintended disconnection. I waited this long to report since I reported problem verbally to dealer immediately after trip and just found out this site exists. I just bought a 2000 Venture van, and harness/connection has changed slightly but still seems susceptible (I taped connectors to receptacles as a precaution).
Electrical wires continued to short circuit, resulting in loss of headlights and tail lights. Also, smoke entered into passenger's compartment.
