I had a malfunction since yesterday on the signal light on the left side mirror. I wiggled the light and it worked intermittently.

Went to the shop and the mechanic said the contact to the signal lamp was corroded (with green stuff?). He cleaned it up and it is now working.

I asked why not change the contact. He said the contact may come with the whole wiring harness. Anyone knows about this?

 

i got that error code one time but my signal still was working it went away right after
