No tail lights or turn signals

SOURCE: 2000 Saturn sl2 tail lights

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.

i was having a similar problem with my 2000 SL. when the taillights would go, so would the cruise control. and through many bulb and fuse replacements, i finally went into a saturn dealership and they did a recall campaign on it. they did their thing and i havnt had any problems since. FREE!

If your bulbs and fuse are good, then you will need to check the switch located on the side of the transmission. It will have several wires coming out of it. This switch controls your reverse lights

Hard call without inspecting it but it could possibly be a fuseable link. I am not familiar with newer models but sounds like a connection issue. If it has fuseable links then one could be bad. Had the exact same problem and I spent $350 on parts and a days labor until I found the link. 20 min later and $5 I fixed it. i was really frustrated but when another vehicle did it, I fixed it quick
