When I turn the key nothing happens, no interior lights or anything. I checked the battery and it seems like it has enough power, but when I try the headlights they won't turn on. Nothing electrical works. What could be causing this?
Won't start on 1998 Oldsmobile Silhouette
Starting with the battery of your 1996 Oldsmobile Sihouette all electrical connection should be checked to be sure they are clean and tight. The battery should be correctly tested "It seems like it has enough power" is not good enough. If you are SURE the battery is OK then begin with the battery cables and follow the electrical power flow checking ALL connections until you find the problem.
