Pontiac Repair: 1998 Pontiac Montana Transport, pontiac montana, starter system

Question
when i take my keys out of the ignition my van wont turn off. everything else goes off like the radio but then will keep dinging and eventually come back on. what could be wrong?

Answer
Hi there:

does this van have any kind of an aftermarket alarm or a remote starter system If so I would look there first. If not then there has to be a sort some where. 2 or more of the ignition power feeds are touching each other. It could possably a bad ignition switch. does this van have any kind of a water leak into the van that you know about. If so you could have wires are that are corrded together due to the water in the van. those are a few things I could think of it's a bit of an odd question. good luck :-}
