What would cause light smoke to intermittently issue from the vents

In a 1991 Pontiac Sunbird LE? Just guessing here, but I don't think it's electrical as it hasn't blown a fuse. This seems to occur regardless of what setting the controls are on, and is frequent but not constant

Do you
have the same problem?

Thanks for the fast response on that, Roy. Is this something I should be concerned about? Obviously it will take out the heater in time, but what is the likelihood it will disable things like a simple vent setting?

It is a coolant leak. Little now but will get worse in time. I would not delay in confirming it and getting it repaired.
