I have a 1992 mazda 626 with about 150,000 on it. I 've owned it for 12yrs. and have had almost no problems-great car. I came to this page hoping to find out if any of you know about this problem. My heater gets warm but the fan won't operate. Could it be a fuse? I am trying to figure it out without having to spend cash to a mechanic.I would appreciate any help. thanks
