One of the two front turn signal light bulbs on the passenger side was not working causing the turn signal to blink fast. Thinking it was just a bulb, I pulled it and replaced it. Still nothing but noticed when I moved the harness around it would come on. So I disconnected the plug and noticed a little corrosion on the terminals and cleaned them as best I could and the light worked. While I was there I figured I should just to the other bulb in that housing and did the same thing. Now both bulbs work when the running lights are on but nothing when I use the turn signal or hazard lights. Also, when eh running lights are on and I use the turn signal or hazards the bulbs both just stay lit without flashing.

I am assuming it is an issue still with the three terminals in the plug. Does anyone know which terminal I should really look at that causes the bulb to flash vs stay illuminated?

 

try replacing the bulb socket?
