OK... so this all started when i decided to roll my windows down leaving the gym and when i got home my passenger one wouldnt go back up... so after nissan telling me that whole side of the car has failed i tried cleaning out the window motor and yup thing works great... so im not really feeling going back to nissan right now... so i go to roll both windows up and call it a night and everything dies in car.. well battery was almost 4 years old so i replaced it and had no problems for about 6 days til my car started turning off while driving it (its stick so id just jump start it) first couple times i was positive i was just not paying attention and did it myself (lol anything to tell myself to give my car the benefit of the doubt) then my ac nav and all lights would turn off while driving down the road but car ran great? .. we played this game whole drive home and parked it to take to nissan next day but car started just compltely turning off while driving... so i checked my cables and no corrosion or anything but grey fuse/plug? that sorta splits off in two off positive cable wasnt snapped in so i snapped that in and we were on the road again 3 days later now its just not letting me turn it on .. battery is fine alternator is fine i just dont get it hoping someone else might have an idea? ohhh and sometiems it goes to crank up and sometimes it starts all the way up for a few mins then just turns off like its idling to low or something but its not? and then sometimes it does nothing at all.. i swear the car hates me ,, its an 08 with 47k miles on it
