I think I have mentioned this before........but now I am looking for some real answers :o)
The temperature gauge on the GQ is not working. I have tested the connection at the sender...no power.
The temp gauge and oil sender(now working when it wants to) are all on the same relay from the ignition plus the fuel gauge, charge guage and others. Everything else works.
I know you are going to tell me to pull the dashboard out to see if something is loose at the back?
Any luminaries out there with an inkling of how to repair this thing without doing too much damage

the oil gauge senders die - its common.. replace it.
the temp gauge, buy a VDO one and fit it in there! more accurate

Not quite the answer I was looking for. But thanks all the same :o)
Yes will replace the sender eventually. Nissan quoted $116 in
Albany and $140 in
Alice Springs. Cannot find aftermarket ones.

Buy a dashpod, and fit up a oil pressure gauge and temp gauge!
I can get you a nissan one tomorrow for $89.25 for the oil pressure sender...
if your rear window frames are fubar, I also got a awesome price on them from mate at nissan ;)

What do you mean with "I have tested the connection at the sender...no power"
It is not supposed to have power at the sender, it closes the circuit through the sender unit, in other words, if you earth the wire that goes to the sender, the gauge should go to full, if it does, then your sender is faulty, if it doesn't then you have two possible problems:
If its the two gauges at once then it is probably the dash (instrument cluster) voltage regulator which regulates the gauges to a constant voltage so that they don't vary when there are voltage drops such as A/C etc. Depending on the model the regulator sits in the dash itself and its part of the cluster (such as GU) but on GQs I am not sure. Best get a wiring diagram....
With the wiring diagram in hand there should be a 12V feed to the cluster which comes from ignition, if that is OK, then it is the regulator module, if not then could be the ignition switch, and so on....
Most likelly though it is the sender units or earth to them, many people put teflon as the screw them in, that isolates the unit...
Simplest method is: earth it and see if the gauge goes to full if it does, get a new sender, if it doesn't send the car to an auto elect or perform other tests as mentioned.

Now you can see how much I know about electrics lol
Thanks for the advice. I will go and do the tests and report back later in the week.

Hi Willem
I think the voltage regulator for the gauges is either behind the LH kick panel or behind the glove box.
Common problem in NZ I am told it is the salt air!!!!!!!!!!!!!!!!!!!!!!!!
