John, you don't have a lot of options, if you're looking for a miracle minor repair of some sort the odds against it are pretty good. Assuming the button springs in and out like the AM it's probably not a switch problem. Your next hope would be a poor solder connection at the switch circuit board...not likely. From there you go to the actual circuitry controlled by the button, again, no miracles likely, it would then fall into the repair category. Your best option, by far, is to take up the kind offer from Joseph Molino to make you a deal on his pull. John Rahn wrote: > Hello, > > I just purchased an '81 DeLorean vin#06163.
