Check the fuse box. I had to end up replacing the whole fuse box because the board in the fuse box gets to hot and shorts out the left side lights and also the windshield washer would make a weird sound when I used it. Replaced fuse box problem solved

@CraigIt was the ground connector to the fuse box under the hood. I tightened it down and it work but sometimes when your truck went over a bump the ground came loose again and same problem happened. Chevy really need to do something about their ground problem. Almost every Chevy truck has the same issue

@KChangI agree and glad you got it fixed.

tail lights don't flash for turn signal or hazards

Chevrolet Silverado 2012 1500 5.3L 160000 miles
I hope someone can shed some light on my issue. When using the turn signal to turn left, it blinks once normally on the dashboard then blinks on and off rapidly. The tail lights are not lighting up or blinking to indicate that the turn signal is on. I also noticed that the hazard lights also do not flash in the driver side tail light. I checked the fuse box inside next to the steering wheel and noticed the BCM fuse keeps blowing out. I've replaced it multiple times but at this point I'm just wasting fuses. I just got a new battery and ordered a tail light pigtail because it seems like someone'… Read complete

There is a tail light circuit board mounted on the frame. They are known to go bad. They are fairly inexpensive, I would give that a shot.

Have you by chance changed your bulb recently in those lights? If you use a LED bulb without a resistor the truck will think the ball is burnt out and cause that behavior.

I had to change my whole fuse box out but it fixed the problem.

Front and rear turn signals and park lamps not illuminating

Chevrolet Silverado 1995 C1500 5.0L Silverado 118000 miles
While changing some parts and installing LED headlamps and park lamps, I had removed the dash bezel and unhooked the headlight switch. I changed the turn signal blinker to one designed for led turn signals as I had the fast flash after install. When I turned the vehicle to the on position without the headlight switch installed, I noticed a small flash from the terminal the switch plugs into. After that no turn signals front or back and not marker lamps. I switched the blinker back to the original thinking the flasher was bad, and the same thing, no illumination. I am asking for some direction… Read complete

Issues with blinkers and tail lights and break lights

Chevrolet Silverado 2003 Extended cab 4x4 2500 hd 6.0 litter engine gas  210202 miles
So this is my bosses work truck that I drive and ever since I started working for him the blinkers act up when you hit the brakes and the brake lights don't work only the top one on the cab. When you hit the breaks the left blinker sometimes lights up and sometimes it's both. When you plug the trailer in the blinkers sometimes blink really fast and sometimes the just turn on and stay on. There really is no rhyme or reason that I have been able to figure out yet. The issues keep changing and I can't find a rhythm to it it's just so random when it's doing this. The lights have had issues since h… Read complete

Headlight stopped working

Chevrolet Silverado 1995 C1500 6 cylinder 2 wheel drive 204134 miles
They worked last night and I think I turned them on when it was still daylight and they worked. Then once it got dark I was trying to go to the store and started driving down the road and noticed they weren't working. I was just going to turn my high beams on and drive like that but they aren't even working either. My turn signals work and nothing else. Not even the back running lights. We'll actually the back brake lights do work and also the turn signals

First, check if there's any loose connector near the battery or semething damaged. I dont´t know Silverado, but maybe there's a sort of BCM or electronic module that controls all you mention.

Very likely a failed turn signal/brake lamp filament failure. Inspect all lights and replace bad bulbs. Retest operation again

No running lights

Chevrolet Silverado 2016 Chevy Silverado 1500 LT 127000 miles
I recently had an issue with the Battery Distribution Engine Compartment Fuse Block (see pic)
Truck would not start. Zero power. As a quick fix we jumped two of the terminals and that got it started. However, I have no running lights. Everything else works including headlights, brake light and blinkers. Because the Battery Distribution Engine Compartment Fuse Block will not arrive for a few days and I need to drive in the evening, I was hoping a mechanic could tell me if there is a temp fix by maybe jumping the terminals while I wait for the part to arrive. I currently have a 30 Amp inline fuse fuse so the truck will run. Please help
