Experience is a great teacher.
Isn't that the truth!
If anyone needs anything taken apart and reassembled in the left switch housing, I'm your expert. Lol. If the factory were nearby I think I could qualify for a job.
That said, cleaning all the parts for my turn signal switch resulted in like new operation. My signals were always sticky and felt like I had to force them (especially the left signal). Now, smooth as silk and the return to center automatically. Didn't realize how bad they were.
Including the time to "learn", about an hours time. Well worth it.
