When the lights are on, my right turn signal stays lit. Will work with lights off. Read a few posts with the search button and this is what i did so far. Regrounded headlight grounds by each side of the rad support. Pulled bulbs to check for dual filament. Ran a new ground strap from the column to the e-brake bracket. Ran new ground on right front frame to fender strap. Ran new ground on right rear bulb socket to inside of trunk. The column strap was the last repair made. Did this at work and it worked!! All bulbs lit correctly with good intensity. Cleaned up and on the drive home I decided to see if it still works. The problem is back. Same as before. My question is, did I miss a ground?? Could a turn signal switch be damaged inside the column. Tommorrow I am going to remove the wheel and check to make sure the switch is mounted correctly. I bought as new delco one just in case. Any more ideas would be appreciated
