The heater motor in my 1997 Ford Aerostar has started cutting out when the engine is under a heavier than usual load, acceleration, hills, etc. Virtually no air comes out of the vents no matter how high the switch is turned. Any advice appreciated.
Are the 'windows' in the heater ducts opening? Do check your vacuum hoses for any leaks or lose connections in the engine compartment. Let me know if this helped
