It runs and drives, there is nothing wrong with the ignition switch. The headlights, turn signals, power top, and horn do not work.Hi guys, I'm a long time poster on these forums but my last how-to on installing an iPod dock was archived so I'm showing up in the forums as a new user. Anyway, my beetle is now long in the tooth and have run into the dreaded ignition-switch short. Symptoms are as follows. Unresponsive...www.newbeetle.org
Here is a diy; on how to replace the ignition switch, be sure to look for melted plugs, wires and terminal ends, while you are in there.
I'm trying to find out if there is a main circuit breaker that would control all those features. Key was in my pocket for the two hours that the headlights were left on.The ignition switch supplies power to many different things; it isn't just for starting the car. Historically, we have seen; many times, the switch will get damaged and kill power to a bunch of different accessories, thus the possibility of the switch, wires or plug being damaged/bad. It is not a expensive part and easy to install; so, definitely something to consider and checking or just go ahead, replace it, if all other things seem ok.
Always start with the basics; check for blown fuses, check for power, scan for trouble codes, if you have a vw factory level scan tool, like VCDS by Ross Tech, etc.
