rear tail light in the tailgate on the o/s isnt working all the other lights are working fine inc the ns tail light in the tailgate
ive checked all fuses and cleaned all the contacts on the bulb holders
i can hear a slight clicking/ticking noise in the cluster but its very faint
in the haynes manual it describes the relay as being in the engine bay fuse box but i dont know which one
fault code is b3882-04

does anyone have any ideas what the problem could be ?
