Re: Tail Light Problem
If you get power at center terminal with a test light, (careful, don't touch side of socket.) then try grounding (clamping) test light to outside of socket (which is your ground for bulb) . If test light doesn't light, it's bad ground.

If you put the tester on the outlets and it lights up properly but the bulbs dont, you have already concluded that the wiring isn't the problem. unless of course the wires are corroded and simply putting the bulb in shorts it out. Have you tested the bulbs?
in the rear lights you may have two bulbs one is the turn signal the other one is stop light / tail light the stop light / tail light has two filaments, one for the stop light (21 watt) & one for the tail light (5 watt) it is possible that the tail light filament is blown, try replacing the bulb to see if that fixes the problem,also check all the fuses as well.......hope this helps......cheers.
Yes, you need to of course check the voltage coming into and going out of the brake light switch, if 12 Volts are there going out and coming in while pressing on the brake pedal, your brake lights aren't getting a good ground or there is a break in the circuit between that switch & the lights.
On occasion the tail lights will work with a weak ground circuit where the Brake lights won't. Best way to determine this is to just hook up the 12 volt tester to the Brake light hot wire & there at the bulb ground, then in an area away from the bulb that has a good possibility of contact/ground.
Really that's it, if the 12Volts is getting to the bulb but it isn't lighting, if you aren't getting the voltage there and the brake switch is hot on both sides when pressed, the break in voltage will have to be traced from that switch to the tail light to find the problem.
If the 2000 Saturn SL2 is the same as the '99 SL2, then your tail lights bulb is the same bulb as your break light bulb. Now they are dual bulbs, just like your head lights. So just the same way that your brights can work, but your headlight lamp be out, or vice versa, is the same with your break lights. So replace both bulbs and you should be good to go. I just had to replace both mine, one was a tail light out, and the other's break light was out, either way, same bulb. Also, check your manual for the light, or take the light out when you go in to get new ones. I found that for some reason there is some confusion on the bulb in this make in model.
Do you know if the brake light bulbs are working? (are the bulbs good?). (the bulbs have two parts, one for brake lights the other for running lights) If the third brake light bulb is working the brake lights should be with good light bulbs.
