General Maintenance & Repairs - Turn signal stick does not return

When I engage the turn signal and after making the turn it does not return.

Whe do I start looking ...?

gonna take a shot in the dark and say your more than likley have a failed multi-function switch

You have a broken turn signal return spring.
