Help with window regulator

[alexanderLTZ]

Greetings all, I'm hoping to get some advice here.

I've got a problem with the rear driver's side window on my 2014 Sonic Turbo LTZ. I'll explain and hope someone here can help me get going in the right direction.

A few weeks ago, I lowered the rear windows from the driver's door controls. When I tried to raise them, only the passenger's side window went up. I tried from the rear door control as well and it was still not going back up. After pressing the up button on both the front and back door switch numerous times it finally raised. I decided to just turn the child lock on and not lower it for a while. Unfortunately I was a dummy and pressed the wrong switch the other day when I was going to lower the front window. Now it is stuck halfway down and will not raise. I have tried both switches numerous times and tried different techniques such as holding the switch up while starting the car, etc. I even removed the door panel and checked the connection of the wires to the switch (disconnected and re-connected it) but it is just stuck. It will still go down, but never up.

Has anyone had this issue? I'm moderately mechanically inclined, so should I try to replace the regulator itself? I'm not under warranty anymore (I don't think, I just passed 50k miles). If it's more likely a wiring issue I wouldn't be able to do much myself except replace the switches themselves, but I doubt they both stopped working on the same day, in the same direction.

Any thoughts?

dumb question, but does one switch need the other to work correctly ?

Does it all come from the drivers switch to feed the rear switch ?

I know i read on here somewhere that a switch in the rear didn't work and they replaced the front switch and all was dandy....

Chris,
Honestly I'm not sure. That does sound likely however because it would explain why they both stopped working at the same time...

It's been a few ears since iv had this problem on a different vehicle. But I believe if you hear the motor spinning that means the regulator needs replaced but if you don't then you just have to replace the motor itself.

If you do replace it can you do a how to video.

(Replaced regulator on 09 impala and replaced motor on 4th gen camaro.)

Did you ever get to the bottom of this?
I have the exact same issue going on with my vehicle right now.
I'd love to know how you fixed it. Cause I opened up the panel and I don't know where to start.

an electrical diagram would be helpful in helping diagnose the issue. I am pretty sure window switches , light switched etc. are controlled probably by the body control module. A digital multimeter with a schematic of the system can help solve your problem and prevent you from wasting money buying parts you don't need.

Drivers door switch panel is the most used an most likely to fail. This is a dominant switch, along with the child setting. The rear switches only work if everything up front works.

Unless you are 100% sure that current is getting to the motor and there is no motion (you can check for 12V with a multimeter and a helper), I doubt it is the regulator or motor at 50k miles.

The master switch is $25 on rockauto.com.

Pull the door cover off. Disconnect the wire pigtail. Put your volt meter on dc and put them in the prongs. If you push the switch and your meter shows 12 Volts, then your switch is fine. Replace the motor.
