Back windows won't work, even when drivers side window lock is used.

It sounds like it could be the window solenoid, or the window motor. It's unlikely the switches on both doors are bad. Check the solenoids and motors...

if more than one power window not working you have blowed fuse or you have window on lock out mode on the master control switch on the driver side.if master window control switch on driver side wont work but 2 windows will work using their switch the master control switch on driver side is bad.

make sure power windows lock out switch on driver side not on position, that will cause power windows not work or you have faulty power window relay.

Probably the power window motor.
You would need to know if the motor is getting voltage.

Time to wander through the spaghetti of wires and contacts with voltmeter looking for a closed circuit to ground. Sounds like the radio is where to start.

That is like asking why your grass grows faster one week than the next

You use the window switch a lot --- so start there

Next, is the window regulator or cable broken -when
that happens the window usually falls down

The window motor may have fail in some way

I know you should check for a blown fuse but the other
windows work & if it did blow replacing it won't do a thing

If you have & know how to use a volt meter on any setting,
start by getting access to the switches

I doubt the locks are even on the same circuit

Personally I wouldn't even approach the vehicle
without a wiring diagram
Like going on a road trip,no map,why leave home
won't find anything or get to any place

Most people ask a question & go to a repair shop
or try thing the hard way because it costs nothing

Also gives no results

check and see if the window lock is on or not, driver side window and sunroof will still function when window lock is activated however, the other windows will not work, even by the drivers control, it should be the button on the top right next to your power door lock switch,

There are broken wires in the wiring harness between the frame and your driver's side door. These wires control all the windows and door locks in a 95 Jeep. Same thing happened to me. You will have to cut the rubber boot to get it off and check which wires are broken and repair them.

Replace the Driver side window switch. These have a corrosion issue.

slide the rubber boot up and check the wires in the hinge of the doors. I will bet anything that the wires are broken. that was what was wrong with mine. just splice them back together and everything should work fine.
