Driver's door power lock problems
 

Occasionally the remote will unlock every door except the driver's door, and at times the button on the door will not lock or unlock the driver's door. Any idea what is the problem? Thanks in advance!!!!

If they are any similar to Honda's PDLs, then accumulation of grit in the motor commutator can cause that. In my Honda I disassembled the lock down to the motor, pulled the commutator and cleaned with cotton swabs, electronic contact cleaner and fine sandpaper. Works for 3 years now.

Provided that you made sure the PDLs are getting 12V and ground all right.
