1997 Mercury Mountaineer V8 Four Wheel Drive Automatic 125k miles
1997 Mercury Mountaineer, Heat problem. Occassionally a delayed flapper could be heard opening from underneath the dash and then the blower would come on. The Blower had only worked on high speed setting. Now Nothing! No Blower, No Flapper noise. No Heat At All. Any Cure?
It appears to me the blower motor is controlled by the flapper opening. Sometimes the rear heat will blow warm without the front blower actually operating.
