Hello All

Problem - Had a light front ender last Friday in my 1996 GL w/120,000 miles on it. Cosmetic damage to front fender assembly, cracked inner fiberglass radiator support. Very driveable, no issues with regards to running or driving

Issue no.1 - with headlights on, dash emergency light indicators stay lit

Issue no.2 - Use of directionals (left or right). Directional flashing speed is now approximatley double that of normal flashing speed. This occurs whether the lights are on or off.

Any ideas what to look for. I am more than a little stumped.

Thank You

Bob

Turn signals flashing twice as fast usually means a bulb is burned out.

And dash emergency light indicators? Which light is that?

The emergency light indicators are the dashboard directional indicators, only both of them indicating the hazards are on.

Thank you

Yes, the front turn are functioning normally, other than the double speed of the flashing interval
