Erratic door locks along with non-operating power windows...

'97 Lexus ES300

While driving, my power locks will lock and unlock erratically by itself. If I try to lock my doors, they will lock then immediately unlock. Also, my passengers are unable to roll up or down their windows, as if i locked them. Only I can roll down all the windows from the master switch. The drivers side rear can roll down their window, but can't roll it back up.

I already replaced the window switch but to no avail.

Any help is appreciated :D

Check the wiring harness going from your driver's door to the dash. There may be worn insulation or shorts.
