I posted last week about my 90 accord electrical problem. After a rain windshield wipers, oil light, parking light, and various buzzers went on and off at random. When wipers turned on, even pulling the fuse didnt shut them off. My mechanic said he didnt do this sort of electrical problem.
I found a one man shop to look at it. Left lower corner of windshield leaked. The control unit by the drivers kick panel was wet. The circuit board had mold and rust. Fixed windshield leak and replaced control unit and problem is fixed. (I hope. Its supposed to rain tonight so I will find out.)
I didnt know there was an electronic control unit. Given the weird symptoms I am surprised no one in this group suggested the control unit.
