When I indicate left and straighten up the wheel after a turn, the indicator doesn't toggle off by itself and the lever has to be manually pulled up to turn off. The right one works as it it should and toggles off by itself. It's not that big of a problem but it gets pretty irritating when I forget to turn it off and I notice I've been indicating left for the past half of a kilometer anybody have any idea on how to fix this?

 

There is a plastic cam on the turn signal switch that sometimes breaks. You can buy a replacement from most auto parts places. You have to remove the steering wheel to do the job.

 

Cool, sounds like an easy job. Mine has the exact same problem.
