Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there thanks for the question.
When the 4wd warning light comes on the indicator display will go off because there is a fault detected and the 4wd is not operational because of it.
Have you had a chance to get the code pulled or noticed any other lights on at all? like ABS or ATP or anything of that nature?
So you can put it in neutral, shift to 4lo normally, drive around, shift back into neutral and shift out of 4lo, and it works normally?
only the auto or "4hi" is causing the issues?
have you tried the diagnostic to make sure it doesn't throw any flash codes?
Just let me know if you get anything, then we will proceed from there.
The dropping resistor and transfer relay are on the firewall on side of engine bay that you were referring to, now if the actuator wasn't working on the transfer case or something you might consider that, but that's not the case here so i am not thinking you have a relay or resistor issue here.
Ok, if it's not working for either one then i am concerned it might be an issue with the actuator on the transfer case.
You can access it on the right side of the transfer case its a black unit. If you can find a helper you can have them try to operate the 4wd and see if you get a clicking or operation from the unit.
If you run into more questions or concerns just ask. Follow up is free.
Just remember to leave a kind rating when you get a chance so the site credits me for my time.
