'99 Chevy Malibu, Air Bag Replacement
Q:
I would like information and any suggestions, on what I need to replace in the air bag system after both bags deployed.
A:
ALLDATA Information System provides the following information from GM. This is just part of what is involved in correctly repairing an air bag system after deployment. "After a collision involving air bag deployment, replace the following components. 1. Inflatable restraint IP (inflator) module. 2. Inflatable restraint steering wheel (inflator) module. 3. Inflatable restraint Sensing and Diagnostic Module (SDM). After a collision involving air bag deployment, inspect the Inflatable restraint Steering Wheel Module coil and the coil wiring pigtail for melting, scorching, or other damage due to excessive heat. If you detect any damage to the mounting points or mounting hardware, repair or replace the mounting points and mounting hardware as needed." To correctly service/repair an air bag after deployment is an involved task that must be performed properly to return the system to working order. If you do not have the training or equipment to correctly perform the repairs I would strongly suggest you don't! You cannot take shortcuts when repairing an airbag system. Short cuts may result in the air bag system not performing as designed or even performing when is not designed to.
