Have brought it to Garage and they've checked it inside out, the fuses even rebooted the system by unplugging battery. Their is power to the positive groung but no power to negative ground. This happened after I was installing Led lights .Did someone have similar problem and what they did . thanks so much

 

Have you tried putting the stock bulbs back on and see if it works? If it does then it's the LED that has a problem

 

This is the first thing that should be done

If the "garage" didn't do that, smh.

Also, LEDs are polar specific - if it doesn't work one way, put it in the other way.
