Both my back windows just quit working at the same time. I thought it could be the regulators but they never fell down, they just quit. If you try rolling them down from the driver side control you can hear them clicking but nothing else happens. Help me!!!!!!!!!!

 

just because they didn't fall down doesn't mean it's not the regulator
it could be other things, but the regulators are VERY common

open up the door panel and see if you can tell whats going on
instructions at www.bignissans.org.uk in the J30 section in the common faults

 

so they would both go out at the same time?
