BMW 540i

This BMW had some wierd electrical issues. Pretty much everything in the dash was not working, lights, tach, speedo, gauges, ect. The blinkers worked on the outside of the car but did not light up in the dash. A/c worked sometimes.

The owner took it to a repair place and they said he needed a complete new dash. The owner was just about to call the local BMW stealer when I jumped in.

I told him that I would fix it. I did a little research and found out that this is not to uncommon. I ended up disconnecting the battery for a while (at least 5 minutes) then hooked it back up and everything is back to normal.
