1999 Saturn SL2 Electrical Problem--Help!!!

I have a four door 1999 Saturn SL2 Automatic that just recently started having electrical issues. About two months ago was driving in extreme heat, shut off to fill with gas, and would not restart. After sitting in shade for about an hour (jump did no good battery fine) it restarted and made it home and then died again. Helpful mechanic diagnosed it with testing meter to be Relay switch--and we replaced the main one and the one that controlls the AC to be safe (and even bought two spare just in case). Ran great for about a month. Then another scorcher....died....remote keys/alarm would not work/radio would not work/car would not start/ headlights work/interior light works/dash lights come on when try to start.....no fix when change out relay switches.....Let car sit for 2-3 hours....started and ran fine for 1-2 weeks (but radio/clock all reset)

Happened again today...very hot and humid...all above symptoms...towed home....called mechanic and described...he wants me to research too as he's stumped. Luckily home and so is car...and can borrow if can...research seeming to say to start with Crank Position Sensor? Does this sound posible? I'm sure it will be tough to test as by the time he can look at it, it will probably start again...and I do not have much knowledge or meters...I just need advice to help point him and not empty my bank. Any/all help will be GREATLY appreciated!!!

    Hi,

    I've had a sort of similar problem on my 1996 SL-2. Mine has a small security key right next to the ignition. I just leave the key in all the time. When my car won't start, I take the key out and put it back in and it usually fires right up. I don't know if that's helpful at all.

    Thanks found my old extra security key they gave me to keep in my wallet when I bought the car new in 99 and even followed the "reset" directions in owners manual for alarm---but it's deader than a doornail this time---something's really blown and it's not those relays as I put new ones in...but thanks!

    I have a 1999 Saturn SL2 and it has electrical problems but very cold here 18F. About a week ago I started my car and the lights came on and off then it stalled. I restarted it with no problem. Then a few days ago the speedometer and the RPM dials would go to zero as I was driving on the highway and then go back to normal. The engine did not stall at all this time. The same day I stopped at my Moms to shovel snow and when I went back out to start my car there was no power. I tried again a half hour later and there was power to the clock and dome light but the engine would not turn over.

    1999 sl2 stalls when driving or sometimes at start time. very intermittent. clock and radio always lose time/settings when car fails - even won't get reception only static when car is trying to turn over.. after numerous trips to mechanic who kept saying it was fuel pump/filter- now they tell me today they got a code on it and it's the crank circuit. perhaps the other times it was in shop car wouldn't start so couldn't get code. am hoping this $23 part will fix problem this time as car has been great other than this. i used a walmart copy in my ignition when i first got car 4 years ago and it's a tiny bit too long and i don't know if it messed up the ignition or what, but i only use my saturn key since experiencing problems early on with turning the copy key.

Hopes this help, found answer on Saturnalia
http://www.saturnfans.com/forums/showthread.php?t=135171
If your mechanic has a schematic or looks in the owners manual and checks the loads listed for the IP BAT fuse in the UHJB and they are all dead then its the F-5 connection. The fuel pump is a direct feed from the IP BAT to F-5 to the fuel pump relay. the fuel pump fuse is on the other side of the fuel pump relay.

It covers exactly what I am trying to tell you. Check the IP BAT loads, if all dead, fix F-5 and if the internal wire is burned open replace the I/P panel.

File in Section: 08 - Body and Accessories

Bulletin No.: 03-08-45-001

Issue Date: May, 2003

Circuit 402. Loose terminal at the instrument panel junction block. Go to the back side, drivers side of the fuse block and reove the grey 64- way connector. A 7mm bolt in the center of it. Look at all of the connections, possible hot spots, if terminal F5 looks hot, replace the terminal and the fuse block.

Hello there ThreeD, Johnny

I wonder if we had the same dealership? If you are still having the start up problem, I have several solutions.

To Disable the Starter Kill:
( Tools: flashlight, wire stripper, Jumper wire w/alligator clips)

  • The most common intersect point is at the base of the steering column. Slide the seat back, tilt the wheel up and contort your way down there.
  • You should find two wires, usually the same color that look like an afterthought. One comes from up the column, the other, from the firewall. Where they go in the same direction, they are going to the alarm module.
  • The alarm module is usually under the center console. You don't need to dig it out, only confirm the two wires go to the module.
  • When confirmed, choose a spot where the wires are close together and strip about 1/8 inch of insulation from each.
  • To kill the Starter Kill: Use the alligator clip wire to connect the two wires.
  • Now try to start the engine.
What you have done:
  • When engaged, the starter kill interrupts the power going to the solenoid.
  • When disengaged, it allows power to the solenoid.
  • The relay the accomplishes this is sometimes not up to the task, resulting in scorched contacts.
  • Bottom line, the interrupt state never ends.
  • The jumper you attached takes the place of the damaged relay to the extent of allowing power to the solenoid
This is a quick inexpensive way to either fix the starting problem or rule out the starter kill as the weak link in the circuit.

Let me know the results. If necessary we will take it to the next level.hanks for using FixYa

SOURCE: 1997 Saturn SC2 won't start; not even when jump

Auto or manual? If its auto try puting it in neutral and try starting. If manual than try pushing the clutch all the way to the floor. There is a switch on thr pedal that when pressed it enganges the starter.

This sounds somewhat similar to a problem I had with my 1999 Saturn SL2. There was "burning and arching" on the fusebox and it was replaced. The first few times my car would make an extra beep noise when locked or unlocked and I believe the radio/clock had to be reset. The problem got worse although sporadic. Eventually the car wouldn't start - not even making a clicking noise and a big variety of electrical components would not work or didn't sound right.

On my 93 saturn sl2 in order for the car to crank and start i have to turn the right turn signal on. If i do this it starts every time. Do i have to replace the whole ignition blinker and light cluster?


Have you done any wiring changes in your car recently? There should be no interaction between the turn signal switch and the starter switch. You do not need to replace your light cluster. In fact, I don't think you have a problem with your turn signal switch, unless, of course, the turn signals do not work. Do you have access to an electrical schematic and a voltmeter?

Help! I have 98 Saturn SL2 that was live one minute dead the next


Sounds exactly like my 1999 SL2 which had "burning and arching" in the fuse box. Car one day be fine the next I'd take it to the store, come back in 10 minutes and wouldn't start, no radio, no power windows, no keyless entry remote, no rear defrost and even locking doors from inside power buttons it sounded odd. This fixed the problem by replacing the fuse box.

Guessing there may be two issues. One might be "burning and arching" of the fuse box. My 1999 SL2 would periodically not even make a noise to turn over and that fixed that. It also had issues that some electrical components wouldn't work at the same time.

1999 Saturn SL2 electrical problems with fog lights, cooling fan, ac, running lights. None of them are working.


first place i would start are the MAXIfuses in the main fuse panel in the engine compartment, they are huge green fuses that should be 30A. but they control a large array of things.
