I have a 2002 Saturn L200. One day it would not shift into drive. Read the owners manual to override the issue. When getting home I undid the negative battery cable to reset. Worked for a week. Again not going into drive. Negative battery cable removed so many times I have lost count. Used and ODB II and no computer codes came up Also took to auto garage to make sure it was the same results and they came up with no codes. Now the lights flicker (inside and out) gas gauge reads E all the time parking lights stay on when the car is off and the key is out of the ignition , no dashboard lights, no automatic door locks, also the key can be removed from the ignition while car is going down the road or just sitting running. Binging noise on all the time as if a door or trunk is open, slamming drivers side door causes doors to lock and unlock by themselves. This car is driving me nuts ! After reading so much of "what could be wrong" I am looking for an answer to tell me what to do from the cheapest fix to the most expensive and in the order to do it. ( I have read about cables needing adjusting, fuses replaced, tumblers replaced, passlock sensors and BCM) I really want to fix this car as I have sunk so much money into it seems like a waste to just junk it. All suggestions would be welcomed with much Aloha!

I have to ask if first if you've checked the battery and charging system? They control all these things by way of computers. The computers don't like low voltage readings. Make sure that the battery is fully charged and the cables are clean and shiny inside and out and theyre tight enough to not be removable by bare hands

Aloha Knowledge is power,
Thank you for the quick reply. I have not checked the battery charging system, but will later today. However, It has no problem starting up. The key fob wont work when the security stuff happens. I have used it to jump another car a few times and have had no stalling or anything to indicate there was strain on the charging system. I will however check with my voltmeter tonight and get back to you with the readings if that is ok. Thank you again !

That's great! If it checks ok, then the security system may be wacky. I believe the gauge cluster is part of that on this car. GM cars have common gauge cluster failures.

Aloha Knowledge is power,
I checked the battery with my voltmeter and all is well running at 13. I did a reset (auto learn) on the pass lock sensor and it worked for a couple of hours, now back to the same old Bull Sh.T. Any idea on where the gauge cluster is located THX

If your car is generating 13.1 volts while it's running that's not enough it should generate no less than 13.5 V with all of the electronic accessories on. 13.1 is too close to just plain battery voltage it needs more voltage than that

13.1 is a fully charged battery. Why do you say that it needs more voltage then that?

It is running at around 14.5 while running and 13 when just sitting(not started)
Sorry for the confusion, a mechanic said it might be a piece by the break pedal that is causing this, I know what he is talking about but it seems really far fetched but then again with this "classic" car it could be a bunch of different things. Any ideas?
Thank you

I went back and read your original complaint. I am inclined to believe now that you have an intermittent wiring issue that needs to be resolved. I would start wiggling and inspecting wires to see if you get a reaction. I would take the gauge cluster out unplug it and look at the contacts and plug it back in and see if that makes any difference in the gauges. They can be cleaned with a Q-tip with alcohol on it

Aloha, did you ever find out what was going on with your car? Mine is doing the same exact thing. The garage I took it to, thought they had it fixed, after I paid my bill, went to drive it away. Same thing. Went to a GM dealer, purchased new key. Same thing. After work, I stopped by the garage, it started right up, turned it off. Same thing. So frustrated. If you could tell me what they did to your car, I would know what I need to tell the mechanics. Right now. They are scratching their heads, with no clues. They tried to relearn the system. To no avail. One guy says steering column. And I don't even want to think about what that will cost. Any help would really be appreciated.
