Driver door won't lock or let windows down.

is there 12 volts going to the door and inside the door????

maybe look into replacing any fuses that may connect the switch to the windows

How do i check to see if 12 volts are going to the door? And yes i checked all the fuses.

I had the same problem. Jeep used really cheap wires. Find the boot in between the door and frame pry it open and tug gently on the wires. I had 3 wires that broke. So get some wire and either re solder them together or use wire clamps.
