Headlight issue

Different harness length to motors have different internal resistance which means a slightly different voltage delivered to each motor. Motor tolerances means they aren't identical, one can spin slightly faster than the other.

Most all electrically operated pop-up head light cars are like this. I've owned roughly half a dozen cars with pop up head lamps and none of them have had head lights that would raise exactly the same. They've been REALLY close, but not to the point of raising simultaneously.When I replaced one of the gears on my C5 with a brass gear I have noticed it raises a bit quicker than the one that still has a plastic gear. It actually functioned like this prior but since the gear swap the difference has become even further pronounced. That's an exaggerated version of Tsumi's point about tolerances; tolerances between the mechanical and electrical can produce varied operation. It doesn't bother me. As long as they both actually raise, activate, and I'm not having to pop the hood to rotate the motor manually that's the important thing.
