Dome light doesn't work. During troubleshooting found both switches corroded. Top one is from pax side and cleaned up good...now delivers continuity/break in continuity. Bottom one is from driver's side and the prongs don't make contact You can see plastic coming down which keeps two of the prongs from making contact...any insight? Does anyone know if it's normal to have plastic under two of the prongs? Most sites show the driver's side door jam switch to be the same as the driver's side...I bought he car when it was ten years old...so it might not have the original driver's side switch. Any insight would be appreciated.
