warning ding and headlights stay on after car is turned off. However, everything is off as should be.
The only way I have been able to turn them (the headlights and ding) off is to disconnect battery
Thats called the twilight sentinel feature.Should be a knob to right of headlight switch.Is there and have you tried adjusting it?That switch bein bad(shorted)could cause your problem.There should also be a fuse that controls switch.If not,just pull the fuse for the headlights until you get the issue fixed.Pullin a fuse is much easier than unhooking battery.Plus,since your caddy is fuel injected its not a good idea to unhook battery because everytime you do this,the computer has to relearn its idle stradegy which sometimes takes 10-40 starting and runnin cycles b4 it is locked into the computers memory
