Vehicle: 1993 Oldsmobile 98 Regency 3.8 V6 GAS
DESCRIPTION
2.5L (VIN R) Engine
The coolant fan is turned on and off by the ECM, based on inputs from the coolant temperature sensor, vehicle speed sensor and the A/C system. Battery voltage is applied at all times to terminal A of the coolant fan relay and when the ignition switch is turned to the RUN position, voltage is applied to terminal D of the relay. The ECM energizes the coolant fan relay by grounding the dark green/yellow wire circuit (335). The relay energizes and battery voltage is applied to the coolant fan. The ECM opens circuit 335 to de-energize the rela...

DESCRIPTION
EXCEPT REGAL w/3800 (VIN L) ENGINE
Each coolant fan is turned on and off by separate coolant fan relays.
The primary coolant fan relay coil is grounded through the ECM when vehicle speed is less than a speed determined by the ECM and engine coolant reaches 227°F with A/C off and 223°F with A/C on. The contacts close and voltage is applied through the primary coolant fan relay to the primary coolant fan. The primary coolant fan runs until the ignition switch is turned off, or coolant temperature decreases to 220°F with A/C off...
