Thanks to all of the contributors to this group. With your help I was able
to get all of the electrical problems fixed on my wife's '90 Integra GS.
Replacing the ICU repaired the flashing oil light, inoperative rear
defroster grid, intermittent wipers, and occassional sporadic tinkling noise
Replacing bad door switches fixed dome light, and key & headlight chimes.
Once again: Thank You.
