System Testing: Stanza

Start engine. Engage A/C clutch using A/C switch in passenger compartment. Both cooling fans should run at low speed. On models equipped with auto. trans., turn A/C blower motor to "HI". One cooling fan should run faster than the other. On all models, turn A/C off. Warm engine to operating temperature. Both cooling fans should run. On models equipped with auto. trans., if coolant temperature rises to greater than 212°F (100°C), one cooling fan should run faster than the other. If cooling fans do not function as described, check power supplies, grounds, relays, radiator fan switches and motors. If no faults are found, check component wiring. See Figure .
