1994 Chev Lumina Sedan, Smoke at Steering Column

Hi,
My Mom's 1994 Chev. Lumina Sedan
Two different times in the past year, a little smoke came out of the top of the steering column, not far down from the steering
wheel, in the area where the "hub" (section where the automatic shift comes out, etc).
I couldn't find a place (screw holes) to remove the cover so I can look inside. Any ideas what might cause the smoke or how to take the cover off?
Thanks in advance, Brad

I had that problem in both of my Grand Prix's (a 1992 and a 1991). Turned out to be the switch inside the steering column that moves back and forth when you press the turn signal stick up or down. If memory serves, I was told there was a recall on the switch years ago. To replace it, you have to take the steering wheel off, and, if memory serves again, it's right there. To be honest, I never replaced mine in either car. The '92 got rear-ended before I did it, and the '91 got well over 300,000KM's on it before it went to the scrap yard. Signal's still worked fine the day we drove it out there.

Happened on my 91 Regal. Twice I saw smoke but nothing serious ever happened and I've since put on many more miles. For a while, the left turn signal did not stay on once you let go of the lever. Suddenly, it worked again.
Having seen a car fire, when I saw the smoke I was ready to stop and bail. They go up fast.

Same here the first time I saw it. I took it to my GM mechanic right away, he ripped the steering wheel off, showed me what was wrong with it, and told me not to worry about it as it was (at the time anyways) a $300 Canadian part.
I did have the coil pack on the '91 Grand Prix catch on fire one day though. I couldn't figure out why the car was running bad, as it had been doing it for days. I was leaving my place one afternoon, stopped to say hi to a friend, and the car quit. Someone walked up and said "hey, do you know your car's on fire?" I said, "sure didn't", got out, looked, and sure enough, the coil pack was. Now, this was years ago before I knew anything about cars, so we tried to get the fire out ourselves, before the F.D. stopped by and unplugged the battery cable. Good thing we knew them, so we all had a good laugh, and I realized what was wrong with the car. Replaced the coil pack and she ran mint again.
She even ran mint all the way to the scrap yard too. Too bad the body was rusted out, or I would still have it.
