Lightning problems

Hello friends, lightning prblems in my .Vanden Plas Majestic 1990, the left hand indicators & warning hazards front & rear don’t work.other lights are ok. The bulb modules look ok.but I can’t find the CPU although I have looked everywhere.
?Who knows exactly where it is
Did someone ever faced such a problem? The shop manual talks about the CPU but doesn’t show it’s location.
Any help would be appreciated. Thanks, Moshe

Welcome to the forums.
Even though the bulb modules look ok an easy test is to move the modules to the opposite side, if the fault travels then its the module(s)
