Bad ignition switch? - BMW Forum

When I tried to start my car today it would not start. When I turned the key the accessories turned on and stayed on even after the key was out of the ignigtion. The accessories would not turn off until I disconnected the battery. Has anyone else had anything like this?

If you look on top off the starter you will see a single terminal connector with a black/red wire. Hook up a test light and see if there is power to this wire when you put the key in the START position. If you have power there and the engine does not crank, then you have a bad starter and it will need to be replaced.

If you do not have power there in the START position, then the problem could be in the ignition switch, clutch switch if it is a manual transmission or a bad Neutral Safety Switch (NSS) if it is an automatic transmission.

I do have a manual and I can not find anything about a clutch switch. Can you tell me where it is located?
