turn signal out, what to check

[4runner]

MY03 C2 Drivers left turn signal went out last week, I've tried a new bulb, also switched the socket from the other side, no luck. are there any fuses or relays I can check before calling the dealer.

Are both turn signals out, front and rear? Do they work all four using the hazard switch?

My front right side turn signal went out. Found out the socket it'self was all rusted out. Blub shot as well. I had to buy the used socket plug from oklahoma foreign.

Rear still functions, flashes 2x normal speed I didn't think to try the four ways, but locking/unlocking with the remote the other three corners flash. The contacts inside the light housing look clean and dry, tried the bulb holder from the other side, still no luck...

Looks like a power or ground break, inside the head light, connectors or wiring turn signal front left, i would check that first.

Problem solved. adjusted the connectors on the socket, thanks for the help... Now I have a CEL!!! the saga continues
