The lowbeams on my '92 LX are intermittent. The fuses are ok, andthe lowbeamswork, but often they do not. Does anyone have experience with this fault. I have seen posts where others have asked the same or similar questions, but they only receive questions in reply. I suspect the combination headlight/dimmer switch on the column. Does anyone have detailed instructions, liked I've seen in other forums long ago, on how to replace this part.
