2002 Chevy Suburban: there a fuse that controls this cargo door/window

Customer Question

I have a 2002 Chevy Suburban with rear cargo door and window that open vertically. The window will not open when the button is pushed now, and the whole door will not lock either electronically or with the key.   Is there a fuse that controls this cargo door/window?

There are a few fuses that control the lock function of the rear door. they are


MIR/LOCK 3A fuse (switch supply voltage)
DR LOCK 20A fuse (relay supply voltage)
UNLOCK 15A fuse (unlock supply voltage)
LOCK 15A fuse (lock supply voltage)


All are located in the intrament panel fuse block there is also two relays door lock and

door unlock. If they all check out good I would check for voltage at the actuator in the

rear door.
