I searched the threads on this subject. Great info. My driver side lock does not work. I bought a new actuator. Can you check the old actuator out by disconnecting the electrical plug from the old actuator and plugging it in the new actuator before installing and pressing the lock/unlock button? I am also having trouble finding a door latch replacement for my 1996 4 door Explorer. (I broke the electrical connector on the latch.) Any suggestions? Thanks in advance.
