Both headlamps on passenger side stopped working

[claymartin]

My wife's 2014 escalade high and low beam headlights on the passenger side stopped working. We replaced the bulbs with no success. Is there a common relay or fuse that would cause both to fail? Or is there a common ground that may be the culprit?
Thank you.

The ground wire should be common to both lights. Get yourself a voltage meter or at the very least a test light.

30 & 16 are fuses for the high beam and low beam on passenger side.

I forgot to ask, did you even look in your owner's manual or inside the fuse box/relay cover?
