Parking Brake Light Then Air Bag Light
 

Parking brake light indicates malfunction, none apparent. 24-48 hours later, Air Bag warning light comes on. First dealership: Replace right side air bag ($1,000+) but not sure if that is the problem. Second service facility: Replace steering column Clock Spring for emergency brake issue, Found 'chafed" wire under driver's seat causing short that caused airbag light to illuminate. Problems fixed. ($1,013) 10,000 miles later, same sequence of problems. Diagnostics unable to 'pinpoint' issue. Compounded now by engine warning light now illuminated. Any suggestions? Similar problems and solutions before trying another dealership? Bill M.
