Vehicle: 1992 Oldsmobile 98 Regency 3.8 V6 GAS
DESCRIPTION
Two coolant fans, wired in parallel, operate whenever cooling is required.
The Powertrain Control Module (PCM) has two coolant fan control terminals, one for high speed and one for low speed. When the PCM's low speed control closes at connector C3, terminal C4, it grounds the low speed coolant fan relay coil. When the ignition switch is in the run position and relay contacts close, voltage is supplied to the coolant fans. The coolant fan resistors drop the voltage to the lefthand coolant fan, causing it to run in low speed. The righthand coolant fan runs a...

Vehicle: 1992 Oldsmobile 98 Regency 3.8 V6 GAS
DESCRIPTION
This system uses two coolant fans, wired in parallel, both fans run whenever cooling is required.
The Powertrain Control Module (PCM) has two coolant fan outputs, one each for high and low speed. When PCM low speed output is turned on at connector C2 (terminal 11), it grounds the low speed coolant fan relay's coil. If ignition switch is in the RUN position, the relay's contacts close, completing the circuit to the cooling fans. The coolant fan resistor lowers voltage to the left side coolant fan, which causes it to run at low speed. Since the...
