Usually you will find a ***** plug with a large hexagonal head. There is one at the top for filling, and one at the side for checking level. Sometimes there is only one in the side. Gear oil for diffs comes in a bottle with a tube spout. You put in in the hole and squeeze the bottle until the oil starts to dribble out. Replace the plug and you are done.

Hi Owen

Headlights don't work directly from the in vehicle dash switch.

They use very fine wiring to that switch. Not thick enough to supply current to the Headlamps.
Instead, the small switch is used to actuate a magnetic switch with bigger current carrying contacts. Usually close to the Battery & Headlights.
The device is called a Relay.
The contacts are moved by a small low current electromagnet that can be heard clicking.
The contacts in the relay can sometimes get stuck (welded) together which keeps the headlights on when the internal switch is turned off.
Relays are often grouped together in the Fuse Box area.
You can either find the Relay and unplug it and open it up & clean the contacts or strengthen internal spring.
Replace the Relay with another.

Hi Adeyeri

Keep in mind that the Clutch won't engage for a few safety reasons.

Temperature inside vehicle
Temperature of compressor or pipes
Pressure inside pipes
Compressor jambed
Eg It's out of refrigerant Gas

You can momentarily engage the clutch by simply giving it +12v to the wire attached to clutch. Usually has a connector close by.
If it has a Relay (click) in fuse box
You can by pass it with a jumper

A quick engage & disengage should allow you to detect possible problem.
But don't over ride the built in safety for more than about a minute.

Hope this Helps

pull one ignition cable out of cap just enough to see the tip of connector and crank it, a spark should jump from cap to tip of wire. no spark means you need the whole distributor replaced. buy it from nissan or infiniti dealer, it comes with cap rotor installed and 12 mo 12k mile warranty, no matter who installs it. dont waste time with aftermarket rebuilt distributor, those are not reliable. https://parts.infinitiusa.com/

The Starter Inhibiter Relay is usually located behind the fuse panel under the dashboard.
I presume your QX4 won't start or is having a no-crank condition?

If it isn't not working...doesn't that mean it is working?

Attached is a diagnostic for a 1998. My suggestion is a faulty sensor on a solenoid at the transfer case. Let me know if this helps. The amount of flashes is the code for the problem.
