Wiring may be shorted and/or fuses,

circuit breakers blown.

Air solenoid may be faulty. Test air

solenoid valve by shorting across the

terminals of the temp switch to

energize the air solenoid valve and to

activate the fan drive.

Normally Closed Fan Clutches

Problem Possible Cause Solution

Fan runs all the time when

the air conditioning is OFF. Manual override switch is ON.1. Air solenoid valve may be faulty or

plumbed incorrectly.

Air line to clutch may be leaking

(Bendix/Kysor air−off fan drives).

Fan temp switch may be stuck open;

with engine temp below 180°F short

across terminals, if fan turns off,

switch is faulty.

Pressure switch may be stuck open;

turn off A/C system, if fan continues to

run, short across pressure switch, if

fan stops, pressure switch is

defective.

Turn manual override off.1. Check air solenoid valve

plumbing, replace valve if

faulty.

Check air lines, fix where

necessary.

Replace fan temp switch.4.

Replace pressure switch.5.

Fan runs all the time when

the air conditioning is ON. This is a normal condition in

extremely hot weather; spray water

on A/C condenser (fan should

disengage for a short period of time

and then re−engage after water

evaporates).

Air conditioning system may be

over−charged or condenser covered

with debris. Turn OFF the A/C

system; if the fan stops, the

refrigerant pressure switch is

functioning.

Pressure switch may have drifted out

of calibration; use pressure gauge to

compare actual fan−on and fan−off

pressures vs. specified pressures.

Normal condition in hot

weather.

Service A/C system. Check

A/C pressure and condenser.

If out of calibration, replace

pressure switch.

Fan operation is erratic. Loose electrical connection.1.

Fan temp or pressure switch may be

faulty.

Check wiring; fix where

necessary.

If other system components

and connections check out

okay, (a) replace pressure

switch if erratic fan operation

is associated with air

conditioning at idle or (b)

replace fan temp switch if the

erratic operation occurs

primarily when the engine is

hot.

Fan cycles frequently when

engine is hot. The fan should remain engaged long enough

to reduce temperature 7−10єF. The fan temp

switch is defective if the fan disengages after

only a 3−4є reduction.

Replace fan temp switch.

12−FAN CLUTCHES Troubleshooting

12 − 60

Normally Closed Fan Clutches

Problem Possible Cause Solution

Fan cycles frequently when

vehicle is stationary with A/C

ON.

Up to 4 cycles per minute is a normal condition

for conventional control systems; turn off air

conditioning system and cycling should stop.

To reduce cycling by up to 90%, install

an Index K7 fan control system.

Fan turns on whenever

ignition is on (turns off when

engine gets hot).

Air solenoid valve plumbed backwards. Check solenoid installation instructions;

plumb correctly.

Control system fuses blown. If fuse blows whenever the ignition is

turned on, the problem is most likely

related to a fault in the wiring.

If the fuses blow only when the fan

engages, the fault is probably

associated with the solenoid valve.

Check wiring, fix where

necessary.

Use an ohmmeter to check for

a shorted solenoid coil (the

coil resistance should be

greater than 14 ohms). If

shorted, replace air solenoid

valve.

Fan temp or pressure switch may be

faulty.

Check wiring; fix where

necessary.

If other system components

and connections check out

okay, (a) replace pressure

switch if erratic fan operation

is associated with air

conditioning at idle or (b)

replace fan temp switch if the

erratic operation occurs

primarily when the engine is

hot.

Fan cycles frequently when

engine is hot. The fan should remain engaged long enough

to reduce temperature 7−10єF. The fan temp

switch is defective if the fan disengages after

only a 3−4єF reduction.

Replace fan temp switch.

Normally Open Fan Clutches

Problem Possible Cause Solution

Fan cycles frequently when

vehicle is stationary with A/C

ON.

Up to 4 cycles per minute is a normal condition

for conventional control systems; turn off air

conditioning system and cycling should stop.

To reduce cycling by up to 90%, install

an Index K7 fan control system.

Fan turns on whenever

ignition is on (turns off when

engine gets hot).

Air solenoid valve plumbed backwards. Check solenoid installation instructions;

plumb correctly.

Control system fuses blown. If fuse blows whenever the ignition is

turned on, the problem is most likely

related to a fault in the wiring.

If the fuses blow only when the fan

engages, the fault is probably

associated with the solenoid valve.

Check wiring, fix where

necessary.

Use an ohmmeter to check for

a shorted solenoid coil (the

coil resistance should be

greater than 14 ohms). If

shorted, replace air solenoid

valve.
