Elantra/Sonata mirror controls switch is most likely cause. Play with the switch by moving it back and forth between LH & RH a couple of dozen times, then try it again. If it starts to work, the problem is intermittent contact in the control switch. If not, you'll need to check for any problems in the wiring between the switch and the mirror connector pins. If you don't find any problem with the wiring or connections, the problem is in the mirror itself.
