What would cause the parking lights to stay on when the parking light switch is off and the ignition key is out of the ignition cylinder on a 96 Olds Aurora-How do you reset the security system?

Answer 1

== Answer I had a similar problem on my '97. The park lights would come on randomly sometimes draining my battery overnight. On mine the problem was the body control module located on the drivers side above the brake pedal. It is a black box very easy to change. You can find them online from 60 to 100 dollars.

Conversely it could also be the multifunction switch. This is a little black box near the end of your turn signal level underneath the steering wheel cover. It can cause a ticking noise to be randomly heard and cause your parking lights to flicker or stay on, draining your battery. The switch can cost $800 dollars to replace. However, the unit can be cleaned and repaired with contact cleaner and compressed air. This was taken from a post on 2carpros.com http://www.2carpros.com/forum/1999-olds-aurora-vt14769.html

by: duhamelx99 Pardon me for being longwinded but here is how I saved over $500 and you can do it too. You will need to gain access to the rotating contact part of the switch that is hidden under the steering wheel covers but you will not have to remove the switch in order to clean it. You will need to buy a can of electrical contact cleaner and a can of compressed air like you use for keyboards. Both can be had at Radio Shack and both come with the red extension tube that fits the spray nozzle. First move the seat all the way back, then disconnect the battery, remove the sound deadeners, remove the two 10mm bolts at bottom of knee bolster, use your fingertips to pry the sentinel/dimmer assembly and trunk/fuel door release assembly from dash (leave harnesses connected and let dangle) to expose the remaining two 10mm bolts securing knee bolster, remove knee bolster, remove 10 amp fuse for Air Bag, disconnect SIR (air bag) yellow connector at lower left corner behind ins panel, tilt wheel up, use 3/16 or 5mm nutdriver to remove 3 screws securing steering wheel top cover (note that 1 screw is accessed thru the opening for the tilt lever while the other 2 are located on either side of the column closest to the lense/guages), remove 3 more of the same small tapping screws securing the lower steering wheel cover to column, remove black ring of text around ignition lock by pulling straight out, upper and lower covers can now be unsnapped and removed. With your left ear against the mirror control looking just forward of where the stalk goes to the column, you will see 5 tiny holes in a semi-circular pattern. When turning the headlamp switch you can see the contacts moving from hole to hole. Spray contact cleaner in the holes and immediately follow up with the compressed air can to flush out the contact cleaner. Move the headlamp switch rapidly thru all the detents and repeat several times with the contact cleaner followed by several bursts of compressed air to flush out the excess cleaner and dry. When finished, wait 30 minutes to make sure contacts are thoroughly dry then reconnect battery and test. Hopefully all is well and like me you just saved some major $
