Yes, on my '88 GMC Suburban the right side top headlamp is very dim. Tried a
new one, and the same thing.

Also the right side blinker was blinking fast..changed out rear lamp and was
working fine. Then today, I tried turn signal again. No blinking now. Well,
it does, but maybe every 30 seconds. Which leads me to believe the grounding
problem has gone to that side of blinker as well.

Seems the black wire going to the head lamp could be the culprit. While
doing more examining, it broke off from the connection going to the lamp. I
relaced the connector, however I noticed the black wire is corroded, even
after cutting some more wire back to try to get some clean copper, still
more green corrosion. While the others had no problem.

Suggestions on finding it?

Thanks.
