Left turn signal and brake light not working

Asked by JAYBEE8888 Mar 09, 2020 at 06:36 PM about the 2013 Chevrolet Avalanche LT Black Diamond Edition 4WD

Question type: Maintenance & Repair

I have a 2013 Chevy Avalanche Black
Diamond LT. And my left side the running
lights all work but the brake light and the
turn signal and the turn signal on my mirror
doesn't work. I have disconnected the
harness and they back under the bumper
and they harness on my headlight on the left
side and clean them both and put Dielectric
grease on them and they're still not working.

I'm thinking signal light switch. When the switch on my Olds went it made the signal lights do all sorts of weird things. I'd check that first.
