Hi-I'm new. I have a 1996 Trooper S. I just bought it. 180,000 3.2,power locks/windows. Before I picked it up the former owner replaced the ignition switch and switch keys. Since then (they claimed the anti-theft system was working) it does not work. When I take the key out and lock the doors (with a window open) the light flashes for about 30 seconds.
I have tried all kinds of combinations on locking it. The 10 amp fuse is good.
Does any one have an idea of what is wrong>
Thanks-Joseph
