I have a 2003 Dodge Durango all windows and lock switches quit working someone said there is a main wiring harness that runs everything in the driverside door is that true already checked fuse panel.

Best bet would be to carefully remove the driver door panel. There is a wiring harness that plugs into the switch panel (window and door lock switches). The connector may have just come loose.

ok ty if it is the wiring harness what do they call it and where can i get it

Here is a video on how to remove the door panel: https://www.youtube.com/watch?v=5dLDPRjlcko

It is probably not the harness, it is likely either the connection (less likely) or a bad switch. You can find a used switch on EBay or buy a new one.

ty

all the switches dont work so it must be a loose harness
