Can you help? Have 2005 Grand Caravan repairable. Main computer was destroyed in crash. Bought entire front assembly (excluding engine) and replaced main computer, airbag control module, main wire harness, steering column,   dash, including airbags, all from parts van. Installed new pre-tensioners.
   Original van has weight sensor in passenger seat, parts van did not. Airbag light stays on. We tried using the original airbag control module..no luck. Also, tried disconnecting weight sensors.
We are not concerned about the weight sensor...just want to get the airbags working. One more thing, we did not replace the dash wire harness...it is from original vehicle.
       Thanks,   Tony at Auto-Tech
