A couple of days ago, the turn signals on my 2003 Baja starting blinking faster when I accelerated, and slowing down when I took my foot off the gas pedal. I also noticed a faint high-pitched whine coming from somewhere in the car when it was doing this, but couldn't isolate it. I checked all of the bulbs, and none were burned out, so I took apart the head- and tail-light assemblies and checked everything with an ohmmeter for high-resistance to ground. All looked good, and there was no visible corrosion or abraded wires. I also checked the connections to the relay under the dash and followed the wiring harnesses as far as I could.
After I got everything back together, the problem went away for a day or two, but now it's back, and I'm looking for ideas on anything else I can try before biting the bullet and taking it in to the shop.
All suggestions gratefully accepted!
