Headlights problems

[JM Ortiz]

hello I hope you can help me, I had a problem with my Chevy Silverado 2019 LTZ I changed the battery and after that my headlights stopped working, the right low beam works but the DRL does not work and the turn signal does not work either, on the left The opposite happens, the DRL and the turn signal work perfectly but the low beam does not turn on, on both sides the high beam works perfectly as well as the fog lights.

all headlight functions are controlled by the bcm except the high beams. did make sure you had good clean connections on the the battery, you could try and disconnect the battery again for 30 minutes to do a reset

I was wondering if you ever found a solution to this problem. We’ve had many electrical issues with a 2020 Silverado and are tired of dealing with the dealership as they could never seem to fix the problem. It’s my husband‘s truck and his headlights are doing the exact same thing as you stated. Just hoping to find a solution.
