Began with battery cables breaking from acid from battery. I didn't change battery just the cable heads. then headlights began to flick and finally wouldn't come on but the next day went to start car and it wouldn't start so I got a jump and ran OK but no headlights or radio

Disconnect negative battery cable first then positive then remove battery hold down screws and install in reverse. Use rubber gloves to prevent battery acid with skin contact. I prefer using rubber pliers on negative battery cable. I feel its safer. When putting negative battery cable on, place on holding rubber part not the metal contacts.

A simple jump start with battery cables should get the car started and recharge the battery. If you don't like dealing with battery cables, there are products that attach from inside the car using the cigarette lighter to jump start the car that work very well.

levers are usually connected to cables. can you reach under the car to the cable and pull it manually?

Hello,
Purchase the replacement light you need from an auto parts store. Give them the year and particular Saturn S Series model number to acquire the right part. Also indicate whether you need the high or low beam light bulb, as some S Series models require separate bulbs.

Turn off the engine. Pop the hood and secure it open. Disconnect the battery cables from the battery by grasping the cable and pulling it straight off of the positive and negative battery terminals.

Position yourself in front of the headlight you wish to repair. Look behind the headlight assembly to find the wiring harness for the headlight assembly. Lift the locking tab, grab the wiring harness and pull the wiring directly away from the assembly.

Grab the old headlight bulb, twist it counterclockwise and pull it out of the headlight assembly. Replace it with a new bulb and secure it by turning it clockwise.

Reconnect the wiring harness to the headlight assembly and reconnect the battery cables. Test the lights to see if they work properly.

Thanks

Yes.

you got a loose connection there...have the terminals cleaned and tightened properly. Watch out for a short circuits...be careful with the positive terminal as not to touch the negative or the vehicle chassis.

1.Do the headlights come on? Are they as bright as they should be? No? Check the battery cables, and connections. A corroded battery cable terminal end, and battery terminal will cause this. (Even side post batteries have a terminal. It's just a flat area with a threaded hole) Side post batteries are notorious for acid leaking out of the side post area, and corroding the connections. (I change everyone of my vehicles to use a Top Post battery)

2.Battery terminals and battery terminal ends clean? Battery cables good? Then it's the starter solenoid, or the starter itself.

Inside the starter solenoid, (Mounted to the starter. It's that cylindrical looking object on top of the starter), are contacts. These can burn, and wear out over time.

Inside the starter are brushes. The starter is just an electrical motor. The brushes wear down over time, and do not make contact anymore.

If somehow this is the original starter, and starter solenoid, consider yourself LUCKY! It has seen it's use, and is well past time to be changed.

This is a simple procedure, but acid is involved. Wear old clothes and latex gloves and safety glasses.
The battery is visible under the hood. Disconnect the RED positive cable first, often with a 10mm wrench, gently turning the nut counter clockwise.. Hold the cable clamp with a latex gloved hand while doing so and do not twist the wrench unless the clamp is secure or you could snap a battery post. BE Cautious not to touch your wrench to any other metal during the procedure.Next remove the negative cable, same way.
Match the battery with a new one , same dimension, EXACT same terminal locations.
You will generally want a battery with a minimum of 500 CCA rating, this is Cold Cranking Amps. Installation is reverse of removal, clean clamps first with tooth brush, baking soda and water .
Be safe wash your hands and wear goggles or SAFETY GLASSES just in case. ACID will burn your skin and clothes if you tip or spill or break the battery. Dispose of the old one at your battery store. Carry in a rubber bin.

Check the mechanical condition of the battery cables; I have seen cables more than once that appeared OK but battery acid had crept under the plastic insulation and dissolved the copper inside.
I confess that this normally shows up first with hard starting or noticeable dimming of the headlights when other accessories are turned on but you have done the other things I would have checked already so it's time to check the cables coming off the battery at both ends. 

I would suggest that you check to see if the battery is connected properly---correct polarity!

If connected wrong, main fuse will blow. Lights come on because power is routed through the frame (ground) briefly.
Hope this helps.
