Consumer Guide's auto has this as a trouble spot "Doors: The power door locks may spontaneously lock or unlock due to a problem with the master switch. (1995) "

My car keeps locking its self now and needs a master switch. My question is it that big control on the door?

My question is it that big control on the door?

Yup. :biggthump

I had the same problem. Replacing the window/lock switch will take care of it.

did you do both sides or just the drivers?

I just did the driver's side, but I knew that was the one that was messed up. Try unplugging the passenger side switch for a few days and see if it still does it.
