Question about 1999 Saturn SC

1 Answer

I recently purchased an automatic 1999 Saturn SC1. The tail lights and dash lights do not work (stop lights and instrument cluster do). I have been told by backyard mechanics that it could be the headlight switch or the neutral safety switch. So advice from an EXPERT would be greatly appreciated. Thank you in advance!

    All of the fuses are brand new. Went and checked just now anyway and it is still fresh. Anything else it could be?

  • EKreeger Oct 16, 2010

    That is something that had me confused. There is nothing in either of the fuse compartments about the tail lights

  • EKreeger Oct 16, 2010

    It is on the wand, but I'm reluctant to replace it if its not the problem... how could I test it?

It may be the lights switch, but first check for a fuse in the engine compartment fuse box marked "Park". It is not the safety interlock, as that only affects the start circuit. If you have more questions, please let me know.

    Thanks for the speedy response. All of the fuses are new, but I went and checked anyway. That rise is still new looking. Do you know what else it could possibly be? Thanks.

    was there a fuse marked "Tail"? the diagram I read did not have a relay, but maybe I have the wrong diagram. Do you see anything in the engine compartment relay box that is marked "Tail Lt relay?"

    OK, I cannot find the fuse box diagram myself. Maybe the tail is part of another fuse circuit. If you have DRL, that is common. Can you pull the light switch out to test? I think we may be down to replacing the switch. You have it on the wand, right? I do not have instructions for that one, but I think you can get it off the side of the column for testing. Sorry, I just don't have a good manual for your car. :o(

    you would need the pinouts for the switch. I think I found the diagram we need. The power into the switch is on the orange wire and the park lights come out on a brown wire. If you can take the switch off or trace the wires from the steering column to a connector, you can access the wires. You want to check continuity between orange and brown with the switch off and on.
    That diagram also shows that pesky 10 amp fuse in the engine compartment. It's labeled PARK LP.

  • EKreeger Oct 17, 2010

    I've checked the fuse and its good. How do I test the "pinouts" on the switch?

  • Jeffrey Turcotte
    Jeffrey Turcotte Oct 17, 2010

    do you have an ohmmeter? connect to both wires and read resistance. Should be zero with switch on and infinite with switch off. If you don't have an ohmmeter but have a 12 volt test light, check to see if the orange wire has power coming to the switch by connecting the clip to a ground point and the test tip to the cable orange terminal. If yes, jumper the orange terminal to the switch and then check for voltage at the brown wire. Am I making sense?

    if you have the switch out, you can probably tell by looking at the contacts if it is burned up. There will be burn spots around the contacts for the parking lights. Because there is no relay in this design, a lot of current runs through those contacts.

  • EKreeger Oct 17, 2010

    I think I have an electrical toolkit somewhere with a meter in it. Ill check on that tomorrow and see if I have tme to remove the switch. Please keep in contact with me, as you have been infinitely more helpful then anyone I have asked.

Tail lights and dash lights dont work

The common power source for the tail lights and instrument cluster is the 20A TAIL LPS fuse(s) in the fuse block. BUT, in the case of the instrument cluster, there are actually two fuses with the same identification. Replacement of the fuse with the ORG wire connected should restore the tail lights when you set the turn/hazard/headlight switch to PARK and may restore the instrument cluster lamps. If not, replacement of the second fuse with the two YEL wires connected should solve the problem

1988 pathfinder no dash lights no revers lights no tail lights no gaiges

If they all stopped working at the same time then it is probably a fuse or possibly 2. Check your fuse panels in the dash and under the hood. The dash lights and gauges should be a fuse labeled instrument cluster or guages, it is probably blown. The other fuse to look for will be the tail light fuse. This is where I would begin.
