I’ve checked all the fuses and they are okay. However my turn signal switch is broken in two spots. Could that be the cause of my headlights not working?

We need to check and make sure the low beam relay is working. If it is okay then if both headlamps are out it is either the switch, the body controller, or wiring. The way to test this is test the highlighted wiring when the switch is on. If you don't have voltage on the signal wire to the BCM from the switch then the switch is the issue.

Take a look at this and let me know what you think and if you have questions. Thanks
