I have a 95 Chevy K2500 truck. The tail-light flashers and the front (flashing) indicator lights all work. Both tail-light bulbs are brand new. The green arrows on the dash also work. There is nothing connected to the trailer wiring plug, but a tester shows that the power going to the 4 prong flat plug is working normally.
Here's the odd problem. When I signal to the left, the flasher blinks normally. When I signal to the right, the flasher blinks real fast. It's the same flasher (under the dash). And like I said, all lights work like they should.
This has me completely puzzled. I guess it's not a real problem, since they work and are legal, but being that I have worked on wiring all my life, this makes no sense. Has anyone else ever run across this? If so, WHY????
Thanks
