No Instrument or Rear Lights

#1
I have no instrument lights or rear tail lights. Sometimes they come on out of the blue with no apparent reason, but not for long. I have checked the fuses inside the car and under bonnet and all appear to be ok. Could it be one of the larger relay fuses? If so which one?:blink:

I dont believe it is a fuse problem. fuses are either good or bad. being new to the corolla i havent looked @ the wiring of them yet but it may be a possible ground problem. was there any work done to vehicle prior to the lights going out?
