Turn Signal Problem

[Fraser Beatty]

I have a strange problem with my rear left light assembly that I just can't seem to figure out. The reverse lights and tail light/side indicator work. But the turn signal will not work, and neither will the braking indicator when you step on the brake. I have tried everything. I replaced all bulbs with brand new ones (known to be good as I checked them in another truck), replaced the flasher can (also known to be good), replaced fuses, and cleaned the ground in the assembly.

Are there any other grounds in the circuit that I should clean? Is it maybe a problem with an individual wire somewhere between the turn signal switch and the bulb itself? Any other ideas on where to look? Thanks for the help.
