DESCRIPTION

Vehicle: 1992 Buick Century Limited 3.3 V6 GAS

DESCRIPTION

The powertrain control module (PCM) controls both cooling fans by controlling three relays through two outputs. There are two modes of cooling fan operation, low speed and high speed. In the low speed mode the cooling fans are powered in series, cooling fan relay 1 is energized by the PCM and both cooling fans run at low speed. In the high speed mode the cooling fans are powered in parallel which allows the fans to run at high speed. Cooling fans operate only when the ignition is in run.
