HI,
Yeah have the voltage to the compressor checked!..By turning on the A/C when hot (and not working),Add a test wire to the 12v output of the A/C relay, to "boost" the 12v amps/voltage going to the compressor clutch. As soon as the test wire touches a strong 12v source, the clutch immediately kicks in. Remember that 12v already existed on that wire, but a stronger 12v source helped give the clutch the extra kick it needs. Thank you!!..Hope this helps you out buddy!!.. :)

When I turn the engine off the engine cooling fan stays on and does not shut off


depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

2000 NISSAN 4X4 P/U A/C SYSTEM WILL BLOW COLD WHEN OUTSIDE AIR TEMP IS COOL, WHEN HOT OUTSIDE AIR BLOWS HOT.


your auxillary fan is not working. this fan is responsible for cooling the freon that is being circulated in your cooling system... check if there are any loose wires in front of the engine bay.

the auxillary fan is located right beside your radiator fan.

Need to remove aftermarket radio in a 1990 nissan 240sx


Remove the shift knob. Starting on the console around the shifter, gently pull up on the "bezel". When it comes off you'll see the radio's held in (with the little storage area) by 4 Phillips screws.
The wiring is hidden behind

1995 Nissan 240sx will not keep running.


hi

you need to replace your battery.since the alternator is supposed t o charge the battery. y dont you start your vehicle, have it run for 1 hour or go on an hours drive, come back home, turn it off,after five minutes start the vehicle..see if it starts.if it does not, that means your battery is dead.

hope this helps
