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

[heyraver]

'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

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