electrical smoke

My daughter started her 97 Sunfire and had a puff of smoke come from the somewhere in the steering wheel she says.
I went and started it later and din't see any smoke or smell that distinct electric smell.
I took it for a ride and did hear a clicking from under the dash when I applied the brakes off and on.
Sounds like the brake light switch?
I'll check in the daylight tommorow, anyone had this happen?
The smoke worries me.
Thanks
Gary

We found the problem , someone has done some tricky wiring using a small wire to power the brake and signal lights. Now to fix it hmmmm.
