Your HID ECU is faulty or water entered, try take out the ECU and dry it, by vacuuming it, drying it with medium hair dryer or put it in hot sun for a couple of hours...Hi, does anyone encounter the HID unable to switch on. Sometime need to off and on again to on it. sometime just cannot on it. It is only the driver side. I am thinking it could be the ballast or maybe transistor.
Another option is that you can change your ECU by buying from second hand parts shops in Muar or Johor major towns...Thanks, i guess i need to trace the wiring to the ECU then...
