Power locks don't work & driver's door WILL NOT lock
The power locks in my truck don't work period. The passenger door I am able to lock and unlock from the inside and the outside (by hand of course). But the driver's door is what is causing problems. The driver's door is unlocked ALL of the time, I cannot lock it. No matter how hard I push down on the lock thing by the window inside, or no matter how hard I twist the key outside to try to lock it, it will not lock. I tried taking the door panel off (one screw by the door opener, and one screw in the grab handle), but I couldn't get the whole thing off and I was afraid if I took it off I might pull on the PL/PW cords too much and wreck something (the power windows still do work, so I don't want to ruin that also..)
Without further delay, why can't I lock my door at all and how can I attempt to fix it?
* Many thanks in advance, especially if I can fix it. *
