Is there moisture in the headlight assembly? My wife's car had the same failures. They appeared after running it through a car wash.

I removed the headlight from the car and used a floor vent in the house to dry out the assembly. I cleaned the ballast connectors on the headlight assembly with CRC electrical connector cleaner. Then I replaced the ballast with a used one I bought on eBay. Finally I replaced the damaged rear cover with a new one. Then I reinstalled it into the car.

Finally I said a short prayer to the car gods, crossed my fingers and started the car. No warning lights and everything worked as intended.

I hope this helps.
