1997 Plymouth Grand Voyager electrical system problems

When van was hit by another vehicle, on the passenger's side at a high rate of speed, there was no deployment of the passenger's front air bag. Also, horn does not work, remote entry on driver's side door does not work, air bag warning light stays on, fuel gauges does not work, A/C heater blink on and off,inside dome light blinks on and off, steering column freezes, cruise control works on and off.

The instrument panel started going off and on. When it would go off the ABS light would come on and then the engine service light would come on, during this time every thing went out. The speedometer, odometer, gas and temperature gauges went out. I would hit the dash and it would work correctly. I finally had to replace it and that one lasted about a year and a half. So know I have put another one in and at this time having problems getting it to function.
