High beam headlight not lighting even though it has power

[mellor_21]

I have a weird problem.

TL;DR - Have power to the headlight connector but the headlight still won't light up, even though it lights from the other side's connector

I tried to replace my high beam on my 01 WS6. The socket that my driver's side high beam connects to was really corroded so I sprayed some pb blaster in it to clean it up a bit. Tried the new headlight and it didn't work, so I tested the headlight on the passenger side's socket and it lit up. So the bulb is good. I checked the corroded socket with a voltmeter and it had power.. but the headlight won't work when plugged in to it. I figured it had to be something to do with the corrosion in the socket so I cut the wires going in to it and checked them on it and it still won't light. I rechecked the wires with the voltmeter, still had power, and rechecked the bulb with the passenger side's socket, still lit up.

I'm at my wit's end. I figure there's something simple here that I'm missing, but I can't figure it out. Can anyone help?

The ground is where I would look. That is usually the problem. Beyond that, I wouldn't know.

thanks for the help but I got it. It was something to do with the prongs from the headlight not conducting electricity. After I plugged it in like 7 times it finally came on and has worked since.

That was what I was just gonna suggest. The plugs on our cars are weird sometimes. You have a problem, unplug and replug a couple times. Had that happen on the fuel injectors once that was memorable. I took out the intake, put it in, it threw a code. I unplugged and replugged til it stopped throwing codes.

it is possible that you have or had corrosion inside the prongs. After plugging the headlight on and off you finally made good contact. If it happens again I will suggest to replace the plug.

To help protect it from future corrosion put some dielectric grease on the connections.
