My brake lights (2000 Oldsmobile Siluhette minivan) are acting weird, when its only the brakes, only the taillights, or only the turn signal they work fine. but any combination of those 3 options and all the lights come on sort of dim and do wierd stuff, for example the arrows for the turn signals in the dash come on when you hit the brakes with the taillights on.
Anyway I was told it is probably a bad ground wire. How do I go about fixing this? Do I have to re-wire the taillight assembly or is there some other simple fix I can try?

It is definitely a bad ground circuit, what is happening is the light that is on is using the other power circuit for a ground source since it doesn't have a good ground. When you power up both circuits it is forced to use the high resistance ground circuit which is why your light go dim. Your only choice is to find where they ground at and repair the poor ground or to splice a new ground circuit into the taillights.

your problem is more than likely a ground. If you have your taillights on and apply the brakes one of the lights may go out.This will be the light with a bad ground.simply run a wire from this fixture to a good ground. No need to completely re-wire anything.

It's not a battery or charging issue, it's an internal wiring problem. GMs are common for this, the problem could be either the headlight switch or turn signal switch. Because both of these have more than one adjustment, internally when they fail they allow circuits to cross flow the current . meaning they're allowing multiple failures or multiple things to happen at once. Diagnosing may be a problem if you're not familiar though.

The fix will be really simple. Finding out what to fix will present a problem. Most likely, it is a dirty ground somewhere. Intermittent electrical faults are tough to find. You may want to take it to an automobile electric repair shop.

there will be corrosion on the contacts some where in the rear remove clean and replace little piece of sand paper to clean it up and then some amber sol spray that should cure it

Have your alternator and battery checked. It's possible there isn't enough voltage or current produced to run everything.
