Got the codes checked and found the 52 code says

Saturn Sc1, Sc2, SL1, SL2 Automatic Transmission codes when turning right after a reset or when hitting third gear. Intermittant dash lights dead, fuel pump failure and check engine light says various codes having to do with car starting in gear. Mine had a bad ignition switch which burned up the wires connected to the automatic transmission start satety switch. On the back of the transmission a black plastic device connected to the shifter cable. You must remove the black plastic shield from the upper wire to see if the wires inside are burned on the top connector that has six wires. If they are get a junkyard replacement connector and wires. Replace the ignition switch first to avoid same problem.

get the code read and check back. autozone will check it for free. many auto parts store will do it

Does the car overheat at idle? If yes, first check fuse in fusebox in engine compartment. If fuse good, check for voltage at fan connector using test light with engine on and car hot. If no voltage, replace fan relay in engine compartment fusebox. If voltage is present, replace fan. Please reply with any additional questions.

The codes do not necessarily indicate any failed parts. You have to troubleshoot the system to figure out why the light is coming on. It might just be a loose wire somewhere. What codes have you been getting?

first get it scanned for codes 2nd look at the air filter, and the mass air flow unit sitting on top for leaves or dirt , then check the air intake bellows that runs to the intake check it for cracks? also look and listen for vacum leaks around the engine possible cracked hose causing ecm to get false signals from airflow meter? good luck

Most major auto part stores scan or will loan you a scanner free of charge. Get the code and post it here or search on this site:

When the check engine light comes on you need to have the codes read. Most auto part stores will read them for free.

Found a STB on this... (97-T-13A). Applies to all 96's including and above VIN TZ238241. It says the rubber suction hose on the A/C compressor may rattle against the battery tray or transaxle housing...their fix is to cover the hose with a piece of foam rubber.

EGR Valve Pintle Position Circuit. Clean EGR Valve first, if problem persists, it is not serviceable and must be replaced

Did you get the code that triggered the SEL? If you know that, it will be easier to diagnose your problem. You can do it without a tool on the old saturns. Just need a paperclip. :

Use a paper clip to jumper Terminal A and B of the ALDL *Assembly Line Diagnostic Link* which is above your left knee.
Terminal A is an interal ground and is the top right terminal in the connector. Terminal B is directly adjacent and to the left of Terminal A.

Turn the ignition to ON.

All codes are 2 digits between 11 and 99. Codes are displayed on the SES light by flashing the light with short and long pauses to distinguish digits of one code from digits of another. The short pause is used between digits of the same code, long pauses are between codes. Also, each code is flashed three times before going to the next code.

For example, the sequence of code 12 will be: flash, pause, flash-flash, long pause, then repeat 2 times. If Code 12 is not displayed, the self-diagnostic pogram i snot functioning properly.

If only Code 12 is displayed, no system malfunctions have been stored.

Any existing system fault codes are displayed in order from low to high, except for Code 11.

On vehicles with an automatic transaxle and on which exist stored transaxle codes, Code 11 will be displayed last, then the SHIFT TO D2 light will begin flashing transaxle codes of flags.

When all engine codes have been displayed, Code 12 will flash again.
