CTS Headlight problem

Asked by Mar 18, 2016 at 11:54 AM about the 2005 Cadillac CTS 3.6L RWD

Question type: Maintenance & Repair

My right headlight went out. Because the lens was very glazed over, I
changed both entire assemblies, including new bulbs. The right headlight is
still out. What should I look at next?

The headlight wiring and connector, make sure there is no burnt marks and the ground is good, next check the fuses. If that check good then you will have to trace out the headlight wiring on that side to find the broken circuit.

Check Fuses under dash or in engine compartment. Sometimes the fuse box wire harness in engine compartment gets stress and tends to break the wires. Use a tester to see if you are getting power to light socket. Could be bad ground. Again follow the wires and inspect. Electrical is always tricky.
