Ignition Switch
I just bought a 1987 Porsche 944 and think I have ignition switch issue. I turned the car on this am and the radio wouldn't work. Then when I got to work, the car wouldn't shut off. Can someone help me? Also I looked for ignition parts on ebay and there's plastic parts, metal parts for the switch and then the new part where the key is inserted. On most cars, where the key is inserted is the ignition switch but I'm not really sure on this one since they are separate. Also, anyone know any good mechanics in the Hickory, NC area?
Thanks

The electrical part of the switch is usually the part that goes bad. This is the Clarks garage procedure for testing the switch. http://www.clarks-garage.com/shop-manual/elect-17.htm

On mine, it was the lock tumbler that went bad. No amount of key jiggling/wiggling could get it to work. The replacement procedure in the Service Manual involves a lot of disassembly, drilling and replacement of parts designed to fail under attack by car thieves.
In the assembly, there is an internal latch which holds the lock tumbler in place, but you have to cut a hole in the side of the pot metal housing to release the internal latch. I was able to lay out carefully where the hole needed to be, then use a Dremel tool small ball grinder to punch the hole in the right place.
After that, it was just depress the latch through the hole and use the key to jiggle the lock tumbler assembly right out of the hole. New one slid right in, and the car was running again.
Saved all the steering wheel removal, drilling, replacing destroyed parts, etc. Took me about 3 hours, as I recall.
Didn't need to do anything to the electrical in this case.

Try not to have 50 keys on your keychain when you get it back together...It's hard on the assembly. Look at what GM is going through right now. Audi had a recall on their switches in the early 90's for prior years and some trinkets on our cars get pulled from the same parts bin. (I had a pearl 100 Cs Quattro wagon that did the same things as your car.... loved the car... hated the service advisor.)
