When I turn on my left turn signal they flash fast. Right turn signal works fine as do emergency flashers. I've inspected and replaced the front and back left turn signal bulbs. I did notice that when I raise the hood, as soon as the underhood light comes on the front left turn signal glows faintly. I imagine there's a short somewhere but I'm not sure where to begin looking. Any ideas?
Thanks

Pull the bulb under the hood and see what happens.

Then test the wiring with a power probe.

I disconnected the underhood light and still have the same problem. I also tried removing and cleaning up a couple of ground wires I found in the area of the front left turn signal. When I disconnect either of the grounds the turn signal light is still on. Does anyone know where the ground for the front left turn signal is?
Thanks

Not off the top of my head.

However, if you can isolate the ground wire from the park/turn wires (should be easy) try running a temporary fused ground to the body and see if it helps. You can, if you choose, just cut the factory wire, run the temp, and cap off the factory ground.

I may just do that. I dread taking it somewhere to see what they would charge to chase down an electrical gremlin. Thanks for the suggestion.

Good advice from Warlock. DC is a different animal than AC. In DC the rule is "If it dont work, check power. If it works weird, check grounds".
