My 1995 is different from your car, regardless if the switch seems the same. The LCM (Lamp Control Module) in mine I believe is different than a 93, infact year-specific. There are no known issues with a 93 that I am aware of. Wait for a gearhead to post about troubleshooting for your 93 from a FSM (Factory Service Manual), there are always steps to be taken to determine the cause of your issue. I am very sure I fixed my problem recently by replacing the harness to the switch, it was melted when the switch melted, my lazy self did not replace the harness, just the switch, probably causing intermittent connections.
If I were you, I'd honestly start a new post, stating your issue, and what causes it, conditions, etc. I personally don't mind you posting here and asking since it is somewhat related, but the general "idea" behind BC doesn't allow this honestly, and your issue is more than likely entirely different than mine.
