2004 NISSAN PATROL sensor

DIAGNOSTIC PROCEDURE (TB48 ENGINE EXCEPT
FOR THE MIDDLE EAST)
SYMPTOM: Magnet clutch does not engage when A/C switch
and fan control dial are ON.
CHECK INTAKE SENSOR CIRCUIT.
Refer to self-diagnosis (HA-4027) and
intake sensor circuit (HA-132 in Y61 SER-
VICE MANUAL, publication No. SM7E-
2Y61G1.)
CHECK POWER SUPPLY FOR COM-
PRESSOR.
Disconnect compressor harness connector.
Do approx. 12 volts exist between compres-
sor harness connector terminal No.j
1and
ground?
No
cYe s
Check magnet clutch coil.
NG
Replace magnet clutch.
Refer to HA-178 in Y61
SERVICE MANUAL (publi-
cation No. SM7E-2Y61G1).

Check power supply circuit
and 10A or 20A (No.
)
located in the fuse block
(J/B).
Refer to EL section (ªWiring
Diagramº, ªPOWER SUP-
PLY ROUTINGº).
CHECK A/C RELAY AFTER DISCON-
NECTING IT.
Refer to HA-41 in Y61 SERVICE MANUAL,
publication No. SM1E-Y61EG1.
OK
cNG
Replace A/C relay.
