From main switch, both rear windows work, both front do not. From front to passenger door panel the front right works.
Do you
have the same problem?

Okay, so just to put this a different way, all the windows work from their own switch except for the driver front? Also, the driver front does not work on the passenger window?

If this is the case we need to find if it is the switch or the door module. Do you have a scan tool that can see switch inputs in the driver door module? If so, press the window button and see if the door module sees it. If not, we need a switch. If it does the door module is the issue.

If you don't have a scan tool that can do that, we need to check voltage at the door module. However, you need to go to the output of the door module because the switch input is a bus input and you will not get signal voltage to tell you if it is working.

So go to the orange black wire and check voltage and then press the down button on the driver window. Do you have voltage?

The other way is to start with replacing the switch and if that doesn't work, replace the door module.

Let me know if this makes sense.

So I replaced the switch now the front right works from main switch, but not the driver side, but I now hear a strong click compared to a very faint click before, most likely the regulator or motor, will install a regulator/motor unit from a used car, can you send replacement instructions? Thanks

I received the used assembly if track abd motor. When I plugged it in while its still out and before removing the original, just plugged the motor in, I still only heard clicks in the module or whatever it is on too right of the door, but the I tried going up and it moved all the way up but wont go down. I assume the original is stuck same way, its already up and wont go down but clicks, the used one now also does the same, only went up but didn't want to move down. Tried also connecting all electronics in the used one while its still out and same thing.

Thick orange/black wire when pressing switch has voltage.

Removed motor alone and it worked but only one direction, same for the other one. Removed module and plugged it in and only the original works and clicks, the other used one when plugged in only rear windows work, neither fronts work or even click.

Also, whenever ignition on there is a lot of noise under dash listen and see if you have any idea what this is?

Orange/black at the motor via test light pushing switch down I get a light but no motor movement. Pushing the switch up I get motor movement but no light. Orange/light green pushing switch up I get motor movement and light, pushing it down I get a light and no movement.

Naser,

The orange and black wire sends power to the motor to lower it. The polarity is reversed when you take it up. The orange/light green wire should have power at that point. If you have power to the orange/black and it won't go down, I suspect something has jammed the motor from operating. See pic 1.

The idea that you get power at the orange/light green wire when you are in the down position is simply the power returning to ground a different direction. I suspect you will find the same if you try the opposite.

Remove the regulator and motor assembly and inspect it to see if there is something preventing it from moving.

Let us know what you find.

Joe

But I have already removed the motor from the assembly, and it only moves one direction. Same for the used motor I bought only goes one way and not the other.

That clicking noise sounds just like a HVAC door actuator. I have heard that many times and in fact, I just replaced one on my sister in laws 2011 WK (just like this Jeep) and it was clicking like that right out of the box.

As for the window, just to confirm take a look at the diagram. If this is what you have for voltage then that is correct. You should only have voltage on one of those wires when you are pressing up or down.

Can you get a video of the window and what it is doing? You replaced motor and they are both doing the same thing, correct? Then where are you taking that voltage reading? Can you get a picture of the location of where you are getting it?

Yes, both motors while out of the regulator are doing the same, when I received the used regulator/motor assembly it was in the down position and when I connected it and worked I thought that was it, but it just went up but won't go down just like the one I have. As far as wires you mean (looking at it in a set of two wires for each) one of the 2 wires of orange/blacks should light up when going up and the other should light up when going down? And same for the orange/light green? I can take a video tomorrow.

Sorry. No, there should be one of each color. The set of two wires of each color are showing for right hand drive vehicle and Left hand drive vehicle. Sometimes they are different. The RHD and LHD are what show this on the diagram. You want the wires for the LHD vehicle.

So you want to go to the motor and check power on the orange/black wire when you are pressing the down button. We need to make sure we have it at the motor. If you are checking it at the door module which I pictured from your video, then we may not be getting the voltage to the motor.

The DM FL stands for Door Module Front Left.

Yes, I checked power at both. But will check power at motor again at the orange black and shoot a video.

Here is a video showing what is going on. But like you said I have power when pressing down at the orange/black and I have power when pressing up or down at the orange/light green.

The other module when I install it does nothing to neither front windows so maybe it's bad. I still have the other motor as well.

You have voltage on the orange light green when pressing up and down?

Let's forget everything except the door module. That is what is sending power to the motor. If I understand, the first module does not move either front window? The replacement module moves the passenger window properly but only up on the driver side?

If this is the case, then yes. I suspect the door module is shorted. You should only have voltage on one of those wires at a time when pressing up or down.

The black orange wire is the return (ground) wire for both circuits so you press the switch and it sends power to one side of the motor and returns to the module through the ground.

However, if you have power on the orange black (down) wire like you should when you press the down button, you should have nothing on the orange light green wire. However, you have power on that wire as well. So you have power on both sides of the motor when pressing the down button so it does nothing.

I would get another module.
