Default 2008 Silverado 1500 left turn signal dim & fast

I have a 2008 Silverado 1500 work truck. A few days ago when I put on my left turn signal it began blinking fast & I went back to look & the lights are dim.

First I replaced the bulbs that didn't fix the problem. Then I replaced the little circuit board that's under the rear bumper near the spare tire. That still didn't fix the problem.

Any ideas where I can look? Down to one truck until I figure this out as I don't want pulled over for faulty lights.

Again this is left side turn signals only however when I turn my headlights on the left tail lights are dim.

There is no water or moisture inside the taillight assembly

Thanks in advance to anyone who can help me

Only thing I can add\say, clean the cr_p out of the sockets, also use approved bulb grease when putting the bulbs back. This may not fix it, but it's one more item off your troubleshooting check list.

Sounds like a bad ground somewhere; that's all I have for you, sorry.
