How to Diagnosing a Bad Ballast! 
Step 1:Remove the Headlight Bulbs! 
If you just noticed that your headlight is out, open your hood and access the headlight bulb through the access port in the back .
Step 2: Check the headlight bulb!
Remove the headlight bulb and check for any discoloration or cracking. If there is no discoloration, switch the two headlight bulbs from one headlight to the other. If the bulb is not lit, the bulb is broken. If the bulb is lit, the ballast is broken. You need to change the ballast.
