Absolutely correct! This is what I experimented earlier last week. Just take out the switch from the dashboard; would easily come out use a screw driver nib and pull it out. Not remove the jack from the switch; very easy to do. Start your car. Shut it down. Now replace the terminal back to the switch and place back in to the dashboard.
Thats it!! it'll work normal now. No more blinkings!
cheers!
