98' sable "inside light"

my inside light will not come on in my car only if i do it myself! could it be the wiring is messed up?

Most likely the the switch in the door latch is dirty. Some people have had good results with spraying the latch with WD-40 to clean the switch.

It is possible there is a bad ground in the door. Are you having any problems with the door locks?

My 98 Sable wagon has the periodic light will not go off. WD40 - I insert thin red tube between glass and seal as well as any other orifice in the door and spray the a good amount around and the problem goes away till the next time, usually a few months. The switch inside the door seems to have a real problem with moisture. Could be yours is gummed up / rusted open or less likely, a broken wire.

Exactly where do i need to spray at? I don't won't to mess nothing up!

The main thing is to try and get the thin red tube (comes with WD40 can) to poke inside the door cavity so you can get a good spray inside there. You can also go in through the door latch hole. Be imaginative and desperate. WD40 won;t hurt anything. May drip a bit from the drain holes in the bottom of the door but who cares. It is a rust inhibitor as well as a lubricant and is won't hurt low voltage electrical components.

When I open the door the car does the dinging noise!
