Headlights won't shut off?
I washed the car yesterday and I got water on the fuse panel inside the engine bay. Now the headlights won't shut off even in the retracted position and even with the key removed. The tail lights are off just the headlights stay on. I removed the fuse so that the battery won't drain down and put the fuse in after around 10 hours hoping it may have dried out. No luck.
Anyone believe it is just a "wet" issue or something else?
Thanks

test if it will shut off with twlight mode on.
I had to replace my headlamp column switch as a pin/cable had a short at the plug in the steering column.

I'm not sure, I've never had to mess with mine but the wiring diagram shows it controlling the headlights.
Looking at a 2000 diagram, the body control module turns the ALC HDLP relay (44 under passenger floor mat) on and off. I have been having problems with my headlights not turning on immediately and bypassing relay 44 makes them work right so pulling that relay should shut them off. There is a head light off input to the BCM that would be worth checking.

The module under the right headlight only controls the motors to open and close the headlights.
Try turning off the twightlight sentinal or removing the relay as suggested.
Check and see if the BCM or the fuse box under the passenger toe board shows any signs of getting wet.

I'm having a similar sort of problem.... except my headlights work, but not the motors (they won't go up or down) and I also lost dashboard lights and my tail lights....
thing is, it happened right after I changed a light bulb. how on earth could it have gone bad as I changed a turn signal bulb is beyond me. perfect timing perhaps.
I'm thinking the same with you... how on earth can your stalk go bad when you ended up getting little water in your fuse box? lol

The "stalk" is a common c5 failure point but may not be your particular issue.

I replaced the headlight switch and the hazard switch last friday and now everything works great. I'm getting really good a pulling the dashboard after the problems I had with the passenger blend door motor and the hazard switch.
