RH ENGINE COOLING FAN NOT WORKING

1998-2002 Nissan Frontier with 2.4 L KA24D and KA24DE class engines , Cylinder Head Bolts Tightening Procedure :- you have total of 10 bolts , 5 on the LH of engine and 5 on RH ( LH is the intake side and the RH is the exhaust side ) : starting from center LH #1 , #2 on RH center side , #3 LH front of #1 , #4 RH behind #2, #5 RH before #2 , #6 LH behind #1 , #7RH engine front corner , #8 LH end of engine corner, #9 LH front engine corner and final #10 bold is RH end of engine corner .
the Torque spec steps are as follows :
step A- tighten all bolts to 29N-M ( 3.0 kg-M or 22 Ft lb ) step B- tighten all bolts to 79 N-M ( 8.1 kg-M or 59 Ft ib )
step C- loosen all bolts completely .
step D- tighten all bolts again to 25 up to 34 N-M ( 2.5 up to 3.5 kg - M or 18 to 25 Ft lb )
step E- using angle wrench ( turn all bolts clockwise 86+ - degrees ) if you don't have an angle wrench ? do as follows : as final step : tighten all Bolts 75 up to 84 N-M ( 7.6 up to 8.6 Kg - M or 55 to 62 Ft lb ) .
end of procedure .

Power Door Lock Operation
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.
Power Door Lock Components
The power door lock system consists of the following components:
?€¢
Driver door lock switch

?€¢
Passenger front door lock switch

?€¢
LH rear door lock switch

?€¢
RH rear door lock switch

?€¢
LH middle door lock switch (w/ V4U)

?€¢
RH middle door lock switch (w/ V4U)

?€¢
Driver door switch assembly (DDSA)

?€¢
Driver door module (DDM)

?€¢
Passenger front door module (PDM)

?€¢
LH rear door module (LRDM)

?€¢
RH rear door module (RRDM)

?€¢
Left middle door module (LMDM) (w/ V4U)

?€¢
Right middle door module (RMDM) (w/ V4U)

?€¢
Driver door lock actuator

?€¢
Passenger front door lock actuator

?€¢
LH rear door lock actuator

?€¢
RH rear door lock actuator

?€¢
LH middle door lock actuator (w/V4U)

?€¢
RH middle door lock actuator (w/ V4U)

?€¢
Driver door cylinder unlock switch

?€¢
Rear integration module (RIM)

?€¢
DRVMDL fuse (10-amp)

?€¢
PASS MDL fuse (10-amp)

?€¢
RRDR MDL fuse (10-amp)

?€¢
Class 2 serial data link

you checked the master switch ,you may have bad wires going through the door ,I had this problem with my car

Under normal operation, in low speed, only the LH fan is initially in operation. Voltage is supplied to the low speed cooling fan relay through circuit 60 BK/LG wire. When the relay is energized, voltage fed to the LH cooling fan motor through circuit 538 GY/RD wire. Ground for the cooling fan is through circuit 57 BK wire. After the LH fan has been energized for 5 -10 seconds the RH fan will start automatically. Voltage is applied to the RH fan motor through circuit 3829 LB/BK wire. BK wire circuit 57 is also the ground.
Under normal operation in high speed both fans should operate from the high speed cooling fan getting a command voltage on circuit 30 BK/LG wire. The relay energizes both fans through circuit229 RD/OG wire while the low speed fan relays are de-energized.
The fans will come on immediately when the airconditioning compressor clutch is engaged mode and when the vehicle is in Drive. OBD-II trouble codes are P0480 low fan 1circuit, P0481 hi fan circuit & P0482 medium fan circuit.

YES LH AND RH BEHIND RADIATOR

radiator fan sensor faulty. the sensor opperates at certain high temp to switch the cooling fan on.

they are in underhood fuse box. relay 37 is RH fan, 39 and 40 are LH fan, have a good one !!

There are three cooling fan relays in the fuse block under the hood.




The fan relays above are numbered 37,39 and 40

Relay 37 is RH fan
Relays 39 and 40 are LH fan.


You can check if your fans are working by switching on the air con.
Are you having overheating problems?

Regards.

check the cooling fan motor relay, if bad replace it.
the cooling fan motor relay located underhood fuse relay center. LH center of Engine Compartment.

LH/RH lights cable could be disconnected anywhere, will take a long time to trace.
Center Brake Light and LH & RH should be connected at one point.
Jump a cable from Center Brake Light to one of Rear Break Light.
Hope this will works.
