"My 4wd lights on my dash keep flashing when using 4WD, So thought I would change the transfer box oil and check the switches. Oil was looking a bit brown.
Now the switches, using a multimeter the grey load switch on its own seems to work when pushed half way down, then goes intermintant when pushed further?
The black one seems also did not give a reading, But I have a new one off ebay for £15 reading when not pushed in, then switches off when pushed.
Now the Grey one next to the black above I cant get any reading at all pushed in or not?? soaking in WD40 and contact cleaner still nothing
So I decided to open up the black switch as I had a new one!
Here's the new one
Now to open the old one
First off I cut the collar all the way around with a hack saw at the top of the nut just down to the plastic beneath
It pulls apart easy and this is all that is inside, a spring and a contact and how much do nissan want for these!!!!
notice the black gunk
THis is the bugger causing the problem the contact was all corroded
Cleaned up a bit bit and it worked fine once re-assembled, you can see the corrosion
I think the water is entering these switches not from the transfer box end but from the outside, the plastic is not sealed in any way to the nut! so water can easily get in off road spray etc
Switch works perfect now and can be re-assembled easily using areldite to keep in place, take that Nissan!!
So I am now going to do the same to the 2 grey switches

Right just done the two grey ones both in a bad way with corrosion, one in particular was so bad one of the legs of the contact had coroded away! Luckly I have a spare from the black one picture above.
Both cleaned up now work perfectly on a meter! How on earth can nissan Charge £150+VAT for 3 these!!! must cost about 50p to make for a bit of plastic, a spring, contact and a nut.
It is completely point less trying to squirt WD40 in these if you have a problem with 4WD as there is a rubber seal from the transfer box end that wont let WD40 enter the switch. If you dont want to do what I did you could drill a tiny hole in the side of plastic squirt WD40 in there and re-seal with silicone. Mine were too far gone for that.

Are these switches purley just for the lights on the dash to go on and off?
I know the black one is a neutral switch so must be for low range im guessing the other two are just for the dash display

Posts: 31 Hey Space - where did you say you got the 4wd switch from?? Ebay??
I need to change mine out as i have this same problem - or do you think just a cut open and clean and re-assemble would solve the problem?

Posts: 11 Just got this problem myself today, 4WD light on constant and small graphic showing front and rear axles on the LCD display disappears. All works fine if I switch into 4H and back into 2H, no funny noises and nothing unexpected so I suspect it could be the switches. I'm due to change the transfer box oil so I'll do this and replace the switches for new units if I find them on ebay or elsewhere. Are the switches easily accessible before I go crawling around?
