So I put the top down in my 04 350z and cruised to the store. Once I arrived I tried rolling up my windows and couldn't. The door lock buttons don't work, but the key fob does the trick. Window buttons on the door doesn't work, but using my key in the door keyhole rolls them up (in short pulses). And my seats both stopped working as well. This all happened at once.

Also, I can still adjust my mirrors!

Is this a sign of my BCM wearing out? I replaced all other fuses under the hood and driver floorboard. Thank you guys!

 

Welcome- your ZR is a complex machine, requiring perfect coordination between the top, windows and seats to operate properly. It's not possible to diagnose your problem from behind a keyboard. You need an experienced tech with a CONSULT III unit to figure out if this is a switch, sensor or BCM problem. Don't just throw parts at it- pay the diagnostic fee!
