Vehicle: 1993 Cadillac Eldorado Sport 4.6 V8 GAS
DESCRIPTION
Each coolant fan is controlled by individual cooling fan relays. The primary cooling fan relay coil is grounded through the ECM when vehicle speed is less than the speed set by the ECM and the coolant temperature reaches 227°F with the A/C off, and 223°F with A/C on. The primary cooling fan runs until the ignition switch is turned off, or coolant temperature decreases to 220°F with A/C off, or 216°F with A/C on.
The secondary cooling fan relay coil is grounded through the ECM when the coolant temperature reaches 245°F. The contacts close and voltage is applied...

Vehicle: 1993 Cadillac Eldorado 4.9 V8 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...

DESCRIPTION
Radiator Fan
When ignition switch is in On position, system voltage is applied through ignition fuse to radiator fan switch. Fan switch closes when engine coolant temperature reaches 208°F. With fan switch closed, voltage is applied to radiator fan motor. Since fan motor is permanently grounded, fan operates as soon as voltage is applied. When temperature falls below 199°F, fan switch opens and voltage to fan motor is interrupted.
A/C Condenser Fan
When ignition switch is in On position, system voltage is applied to dual pressure switch through h...
