I have a 1998 chevy z71 power windows and locks on the drivers door the window will only go down about 5 inches and the lock doesn't work any ideas

It probably is that either the window motor doesn't work anymore, which can be replaced (a little costly). Or the buttons are broken and can be replaced (not as costly). Unfortunately, I don't really know how to test for which one it is. But if your window moves at all and then slows down and or then stops, it is most likely your window motor dying.

Had a 1979 Pontiac Bonneville where the power window had one of the clips break that held the window when you engaged the button to move it up or down and came up cockeyed. Took it to a glass place and they took off the panel on the door, found a loose wire on the motor-fixed it and put a new clip on the window. Cost me $55.00 I believe the motor should it have needed replacement was $45.00-65.00 somewhere in that range.
