What is wrong with 1999 Buick LeSabre heater and air fan that want work even when you push the buttons?
Just went through that problem with my 1990 LeSabre. I checked the fuse box (panel on left side of steering column where light switches are) and it wasn't a blown fuse. Took it to a trusted mechanic and the problem was the fan motor had blown and needed to be replaced. If you're driving in winter and the bottom of your window is defrosting with the fan not blowing, you're getting heat from the engine through the vent and your fan motor is more than likely the issue.
