1999 aurora when I turn on there is a clicking when I shut it off the lights blink we have to disconnect the battery can I discinect the sercurity I don't want it and how do I do it

Non working turn signals will not drain the battery because they work when the key is on. You may have a bad battery. If your signal lights come on and do not flash, you have a bad flasher which should be located under the dash area. As for the battery, most parts houses will check the condition of the new battery for free. If you think you have a bad battery, make sure that it has a good charge then disconnect it from the system by disconnection one of the cables. If the battery goes dead overnight then it is self draining.

To reset the "CHANGE OIL" light, turn the ignition switch to the "RUN" position with the engine off.

It sounds like you have a malfunctioning alarm system. If it is an aftermarket system, you should simply turn it off. If it is a factory alarm it would really be best to take this to a dealer. In the mean time, to prevent battery drain, you can disconnect the black battery terminal at night when you park the car.

check battery connections ,clean them well and reattch, then let me know

check the connection at the multifuction switch ,ive also seen loose head light relays...

There may be a short causing the relay to turn the lights on and off.

sounds like the security system more than a headlamp switch.

Do the headlights blink regularly?

Remove the plastic shroud above the headlights when you open the hood.The head lights use bulbs that go in from the back,disconnect wiring connector and turn the bulb 1/4 turn to the right and it should come right out.

those are problems with the olds light switches, same switch used on other gm vehicles. replace it , new or salvage yard
