I'm usually pretty good with electrical (not "electronic") issues, but I've encountered something that has me stumped. My beautiful, low-miles 2000 Cherokee 5-speed was in an accident awhile back. Collision damage was repaired properly, but the insurance didn't cover fixing the ruptured brake lines that actually caused the accident. I finally got around to doing that, using copper-nickel (cunifer) line and silicone brake fluid, so I hope not to have a repeat performance.
Now that it's back on the road, there's an anomaly. Right turn signals blink at the normal rate. Left turn signals blink at the normal rate when the headlights are off, but when the headlights are on, they blink faster. No bulbs burned out.
Any ideas?
