Saturn S-Series Electrical/Lighting

    Does the fan come on when you turn the AC on???

    Here's a guess based upon not being there...have you ever replaced your engine coolant temp sensor (ECTS) If the car doesn't know its hot the fan won't come on. Also, the S-series fans come on when the temp needle is just about to enter the red zone, higher than most....

    My power door locks open and close very intermittently whether or not the key is in the ignition. I have tried replacing the relays but the problem continues. The only way to stop the locks is to remove one relay and break the circuit. Could it be the computer? Any suggestions? Thanks
  • i need help my saturn cranks and runs great for about 2 miles then it shuts itself off. we have put new spark plug, wires, new fuel filter, fuel pump and valve cover gaskets
    coil packs and intake modual valve. none of this has helped. does any one have a clue? also the engine fan will not come on

    I drive a 2000 SL1 with about 150,000 miles. I have a 2 week history of weird events, and I'd like to go to the mechanic a little better informed.

    Event 1- I start the car and start to back out of the parking lot. All of my indicator lights stay on and I have zero gas and zero speed. (though I have gas in the tank and am moving.) I turn the car off and the engine cranks but won't turn over. So, I disconnected the battery waited 1 minute, reconnected, and it started fine and everything worked.

    2- Later, I was driving and my fuel indicator rapidly fell to 0, I lost speed indicator and my indicator lights went on (after driving a while this time). I pulled over, turned off the car and restarted. Everything was fine.

    3- Again, I pulled out of a parking lot and lost power steering. I rolled out of the way, and after a few tries with just cranking, the car started and everything was fine.

    4- Last night, I left work and it wouldn't crank at all. My clock was even blank. But the radio would work when I turned it to the fan/ radio on position. I disconnected the battery, 1 minute, reconnect, and it started fine. Started fine this morning too.

    I'm suspicious about the recent hot weather here having a part in this, but it wasn't hot every time. Probably not the battery because most of the time it works.

    Any ideas? How much is this going to cost me?

    I drive a 2002 Saturn SL and have had various problems (steering column, ignition switch issues), which had to be fixed at the dealership. Now, my instrument panel is basically dead. I have no readings for my gas gauge, odometer, speedometer, rpm, or any sensor readings. My turn signals, emergency lights, and inside and outside lights work properly. My clock, cd player, and air work as well.
    I've troubleshooted some and have determined that it's not an alternator or fuse problem. None of the relays are specific to that area either. I believe I either have a short at one or more of the wires at my instrument panel or it's a computer chip problem. The problem does seem too specific to be a computer chip problem (no fuel injection, or any other problems.)
    The problem is finding a schematic or wiring diagram for this area. I don't want to remove the dash and pull or adjust the wrong wire (air bag) and cause some serious problems.
  • it was the crank shaft positioning sensor. thanl you fior your help
  • i have the samething going on what did you find out
  • i have a 2002 saturn s series the head lights will not go off ,i turn off the car and the lights stay on : :mad:

  • my daughters 96 sc2 is having same problems. wipers intermittently turn on. Come on at starting of car, won't go off. Did you ever find a fix?
  • My stepson and myself installed an after factory stereo and now when I start the car within seconds the service light comes on and stays on. We have tried disconnecting the positive post on the battery and waiting as long as 15 minutes. Is there something I am missing? Everything works and I have had no problems with the car since I purchased it 2 weeks ago. Any suggestions, before I spend the money to have it hooked up to the computer code reading machine. :confuse:
  • 442dude442dude Posts: 373
    Go to Autozone or another auto parts store - they will read the codes for free.

    Make sure you get the actual codes and then post them here. I'll keep an eye out...
  • The service light stays on but not the service engine soon light. Oil change, plugs O2 sensor new. Had it scanned at Auto Zone came up with no codes. Any ideas how to clear this?
  • 442dude442dude Posts: 373
    At the Dealer...they're Saturn specific codes and not every reader will read them. Its trying to tell you that something is wrong but its not emissions related. Sometimes its as simple as a burned out bulb somewhere.
  • Come to find out, the tailpipe/muffler bracket was broken completely off. Made a new one myself. After about 10 minutes on the road and another engine start the light was out and has not come back on. Cost: 2 hours of my time.
  • I have a 1996 Saturn SL2 with power doorlocks and windows (including a non-functional moon roof due to leaks it has been sealed shut ... that's another story). The car suddenly started honking all by itself and I had to remove the fuse to quiet the noise. This happened around the same time that the power doorlocks started clicking, I had to remove the fuses to prevent this from draining the battery. Doing w/o the power door locks is something that we can deal with but, not having a honk is a safety issue. This is my daughter's primary mode of transportation and I need to know that she and the other occupants will not be in danger of possibly being unable to warn another vehicle of a pending accident because of not being able to toot the horn. I know that somewhere amongst yards of wires in the electrical system these two items are connected, when they both functioned properly the horn would sound when the doors were locked using the remote. Has anyone run into a similar set of troubles? Not sure where to start with tracing the troubles.

    Bought a 96 SL1 SOHC 3.5 years ago with 261,000 km (now over 362,000) on it. It's a plain jane with minimal electricals on it- lights, heater, rear defog, and radio.

    The first year it was fine, but has gone through 6 replacement alternators since (just put on #7). The battery has been changed twice with the alts. Some of those alts have failed in as little as a week, others lasting 6 months. Some of the alts were making a low volume med-high pitched whistle, after failure.

    Both my mechanic and I are stumped. We both have never seen or heard of such an occurence before.

    Anybody have ideas on what is causing these failures?

    it seems that it is possibly the window motors. I have experienced window motor failures on different cars. One way to find out is to have a helper and one person sit in the car and actuate the window. If it fails to operate, bang on the door with the heel of your hand. If the motor has bad contacts or brushes as most electric motors do, it will start to operate. This will not work on a window motor that has completely failed. Depending on the particular model Saturn, go to ebay motors and search of the switch. I am about to replace a switch in my SL 4 door and they run from $15 up. Also the middle console is quite simple to remove. Generally you will need to remove the panel from the front kick plate by gently prying it off. Now, remove the screws. At the back of the console in the top center you will find two screws. after you remove the two screws, lift up on the real of the console and slide it back about an inch or so. Go to the front and disconnect the wiring for the cigarette lighter and the lamp. It should lift off. This procedure may vary somewhat depending upon the model of your car.

  • I had the same problem. It was the turn signal switch. I ordered one online for $40.00 total cost. It's very easy to install yourself. Disconnect the battery. Wait 3 or 4 minutes. I was told this will disable the airbags.
    Simply pull the top section of the plastic steering column apart. This allows you to see the turn signal switch. Unplug the existing switch and compress the top and bottom tabs on the switch, then slide the switch out. Push the new switch in and plug it in. Snap the plastic steering column back together. Hook battery back up and your done!
  • Has no sunroof. Water gets in car during heavy rains when car is parked. Recently had windshield replaced but I think it was leaking before that. Any ideas appreciated.
