2011 Elantra Speedometer, Tachometer and Odometer Stopped Working
 

My speedometer, tachometer and odometer all stopped working at the same time. My check engine light does not come on and the lights to the gauges still will work fine. It's not a battery problem. My analog tachometer and speedometer needles don't move. My digital odometer doesn't increment (for either of the trip counters nor the total number of miles.) My digital fuel guage also shows no reading. However my digital temperature gauge IS working

I hooked up a Bluetooth ODB2 dongle and ran the Android "Torque" app. I did not have any ODB2 errors and the app was able to show me my speed and RPMs in real time. (I'm not sure about the fuel level.)

The dealer said it would be about $500 just to trace the electrical system which is NOT a viable option. Any ideas would be GREATLY appreciated.

HELP! :-)

Thanks in advance!
