My left side turn signal winker is fast. All rear LEDs are okay but back up light is burned out. Can this cause the fast winking?

Not likely. Double check the bulbs (maybe try regular bulbs instead of led) to see if its the bulb. Might be wet and shorting or relay is bad.

I took out , the backup bulb and tried the turn signals and they worked fine on my truck, make sure the front bulbs and mirror bulb are working

I had corrosion on my rear lamp plug. When it was cleaned up, they worked fine.

Mark, I would recommend checking the bulbs and seeing if there is any corrosion or dampness. If this does not work I would recommend visiting your local GM dealership.

Problem solved. There is a Y-wire coupler just behind the spare tire under the truck. The coupler for the left side wire had become loose. Pulled apart, cleaned and reconnected and now the left side turn signal winks at normal cadence.

Thank you all for your feedback.
