OK just finished doing a little maintenance after my water pump took dump on me. New cap & rotor, cleaned throttle body, new seals in the timing chain cover, new spark plug wires, and a new water pump. Everything went fine except when I tried to start a couple of the spark plugs wires weren't making good contact so first attempt to start ended up just shutting the entire electrical system down hard a few times. Car runs fine now (still a little miss but it was there before I started, sticky lifter?) but I lost the first 3 settings on my blower, heat and AC. Full blast still works great so after looking at a diagram I noticed there was a high blower relay, could this be my problem? Other than the electrical system going down hard and requiring me to disconnect the battery and reconnecting before anything came back on I don't see any of my work effecting that switch. Others tell me it's the switch on the dash.
