Looking for troubleshooting help. new alternator; good battery; no bad fuses. Dash lights flash along with emergency flashers, regardless of flasher switch position. continues even with car off and key out (drains battery overnight, so I am disconnecting batt when I park) Door locks were acting weird; window motor driver side thumping; etc weirdness -- most of which seems to have stopped with new alternator (under-voltage, probably), but this flashing continues. I imagine this is either a bad switch on steering column, or bad flasher unit -- help?
