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

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.
