Technically, no as long as there isn't any power going to the headlamps there is not need to disconnect the battery cable. BUT any operator's manual will tell you ALWAYS disconnect the positive cable from the battery (or disconnect power source) when doing any sort of work on anything that has power, because you never know. If you remove the negative - you risk still grounding to the chassis if you place the cable loosely inside the engine compartment.

How to change head light lamp on a Saturn S-Series SC2


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

    Need to replace headlight lens on a 1996 dodge avenger


    Usually, one has to get the entire headlight assembly to replace the lens.
    Is it cracked?
    If it is just faded, try some anti-haze polish for headlights. This can save you some money compared to restoring the headlamp by replacing the assembly (which may be available from a salvage yard).

    REMOVAL & INSTALLATION

    CAUTION
    Halogen bulbs contain gas which is under
    pressure. Handling the bulbs incorrectly could cause it to shatter into flying
    glass fragments. Do NOT leave the light switch ON. Always allow the bulb to cool
    before removal. Handle the bulb only by the base; avoid touching the glass
    itself. Whenever handling a halogen bulb, ALWAYS follow these precautions:

    • Turn the headlight switch OFF and allow the bulb to cool before
      changing it. Leave the switch OFF until the change is complete.
    • ALWAYS wear eye protection when changing a halogen bulb.
    • Handle the bulb only by its base. Avoid touching the glass.
    • DO NOT drop or scratch the bulb.
    • Keep dirt and moisture away from the bulb.
    • Place the used bulb in the new bulb's package and dispose of it properly.

    Battery? or starter? or what?


    Clicking is usually a frozen starter. But it could very well be the battery. The only way to know for certain is to remove the two and take them to a auto parts store that tests components. Sorry, not much of a solution.

    Good luck,
