taillight/blinker assembly

[992dr]

My drivers side rear blinker is out (flashing really fast in the truck). I was driving home and a co-worker had told me my drivers rear brake light is also out.
I had replaced a rear blinker bulb maybe three years ago, that was it. I never messed with the assembly before.

Are these another common problem?
Could the blinker/brake light assembly be bad?

Any info would be appreciated.
Thanks

corrosion or bad connection in sockets of circuit board.

I went thru two assemblies myself ...

What did you end up getting after the second one?

I have looked on line for reasons why my Tahoe hazards come on when I turn RT but work fine on LT.. Many people said it was the multifunction switch changed it and still same issue even checked all fuse's... PLEASE someone help?

check for proper power circuit and ground circuit separation from each other and continuity in the circuits at the rear harness at the light fixtures and the rear of the frame rails.

Try looking on circuit board for a burnt or broken circuit on it.
