Hi need some help, i changed my interior lights with LEDs.( 2008 A3)

All lights are fine except the plate lights. When i installed the LEDs it didnt work, problem is when i reinstalled the original bulbs BOTH did not work after that.

Is it possible that i blew a fuse? Any help would be great and thanx

 

did you check the fuse? you can find the fuse guide in the owner's manual .. look at the connectors -- is there any corrosion? i had led's in my plate lights, and they corroded really fast -- luckily i took them out before the corrosion got to the connectors
