I have a 2002 Tahoe, purchased used with the rear wiper not working.. I checked the fuse, it's good, the switch only makes noise when I push to dispense water.. But nothing happens when i turn the switch to either speed. I replaced the motor and nothing.. I've been reading and been made aware of a lift gate control module or rear body control module.. Could problem be switch or control unit.
