20 Most Recent 2000 Saturn L-Series Questions & Answers

The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. These 3 parts are in CONSTANT communication. If the key is in the ignition, these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle.

Find what the codes are and the repairs, I would cancel the codes, drive it and if they come back first, sometimes the computer can pick up fault code from a power transformer, Try this first.

Alot of cars have plugs in the floor and are sealed with either undercoating or a type of caulk.over time the seal dries and cracks up letting water in. Raise the car up and find the plugs and reseal with a good silicone caulk. Plogs are usually a oval shape.

I also see that the same problem is showing for the BCM issue ??? Where do you see this ? What happens when you turn the key to the start position ? Does the starter engage an spin the motor ? You have a crank no start condition ? Or nothing happens when you turn the key to start ? Which BCM fuse blew ? Those fuse's power more then the BCM . You have a dead short to ground on the fuse's circuit .

Cannot be window switches. 4 of them do not all go bad at same time. but they all have in common the power that feeds them and is obviously not getting there. Using schematic trace voltage to the switches. Gtranted you changed the relay but is power getting to the relay for it to switch?

have you checked the fuzes ?

The window track should have a bolt at the bottom so the track can be moved away from the window to allow enough room to slip it in between the tracks.Also the door skin can be unbolted to gain access from the outside of the door which may make it easier.

Could be as simple as needing a transmission fluid change to a shift solenoid. Only way to find out for sure is to have it diagnosed.

many auto parts stores will run their diagnostic tool for you free .. that will narrow down the problem ... sometimes its just a loose or damaged gas cap (it has to seal in many cars) .. a bad oxygen sensor is a frequent cause as well .. (especially for a 9 year old car).. but any sensor can be bad or indicate a problem .. like vacuum leaks or misfiring or even low brake or tran fluid .. having it tested is a good starting point .. auto repair shops often charge for this service but auto parts stores do not .. you can call and ask .. the auto parts store will also likely have an service manual but sometimes are not very complete (look thru it before buying) .. your local library may have service manuals ..
