I did the A/C blower upgrade in my GTO years ago and several years later the fan switch started acting up and after disassembly I discovered the contacts were burnt. Fortunately I was able to rebuild them with some solder. It could have been the switch was just worn out from over 200k miles or the A/C blower was too much or some combination of both.

Whatever the cause was I haven't had to mess with it since. Its not a daily driver anymore but has over just 300K on it now. It's likely to last forever now since I picked up a spare switch years ago.

Here is a schematic of the hybrid harness I forgot to post.
