Well my apologies..
All windows but drivers are working... I swear this wasn't the case the other day but will monitor. I'm still suspect of the lock button but it could have been pure coincidence that the amp unit failed at that time.
So now it's just a wait for the new amp unit.
I have done some research and it seems pretty much any nissan around the 1990-95 era ran these modules.
I have a mate who has a 180sx module so for $50 delivered its a but load cheaper than new..
I will prevail with this pita
