where is the ground wire for the brake and turn signals on 2002 silverado chev pu. also do you have a copy of the wiring>
In all probability you have a bad ground.
check the brake light relay under the hood
Depending on the year and if your brake light bulbs double as turn signals, there may be a problem in the turn signal switch if there is no short in the rest of the wiring.
check the turn signal flasher
No. Daytime running light can be disabled without affecting turn signals.
On the left side of the Steering Wheel
Check the fuse panel it is possible you blew the fuse needed to run the turn signals
If you have brake lights and turn signals and a headlight the answer is yeah.
the circuit boards on the taillights are bad.
