I have a 99 windstar 3.8 lx. The passengers window stopped working then it started working again then it stopped again but it has not worked now for months. I checked the switches on both door they are getting power. I hear the relay under the dase for the working window but I don't hear the relay for the non working window. I pulled the panel off the door and unpluged the motor and used a test light and it did not light up so was this the right way to test the motor? I read if the motor is bad you will hear a humming noise when you press the window switch but I did not hear a humming noise just a click coming from the switch.
Last month I was fixing my blend door so I had to disconnect the battery. All my power door locks were working before I disconnect the battery but now only the driver door works. The passenger side and the back two doors and the lift gate no longer work. I can lock and unlock the only working lock from driver door and passengers dor so both switches is working. I checked the fuses they were fine. I have disconnected the battery a lot of times and it never did this. Help this is driving me crazy.
