Hyundai Elantra Master Switch ...again !

The last time I replace the switch was way back in 2015. And now again this switch have to be change or else the power window on driver side and rear passenger can't be lowered. According to my workshop..there was a short circuit and after replacing with new Master switch everything working good...blow away  RM300 after 5 years usage and now it cost me RM490 to replace it.
