What to do if your headlight doesn’t work?

One headlight works on low beam and another on high beam. Or the lights work erratically. Start your diagnostics by removing the FCM located in the IPM. You’re going to bypass that module and try to “hotwire” the headlights yourself to eliminate the possibility of a bad FCM. After you pull the FCM, look at the connector on the front of the IPM.
