Driver's window will not budge/new regulator/new switch

Hello, I'm Danny.

To answer your question yes, I believe you are having a ground issue on your driver side window motor or switch circuit. I've attached the front power window wiring diagram below. Usually the main ground for the driver side is located on upper left dash at the A-pillar. Keep us updated and let me know what you find. Hope this helps and thanks for using 2CarPros.

Hi,

I need to understand something. When you put power direct to the motor, it doesn't run?

I attached a few pics below. The first two are the entire wiring schematic for the windows.

Now, power is present to the switch when the key is in the on position. Take a look at pic 3. I have an arrow showing power in. Based on the direction of the switch (up or down) determines which way power flows to the motor. Direction is changed by a change of polarity. So, when you select up, the dark blue wire at the motor gets power and ground is provided through the brown wire. When you select down, the brown wire provides power and a ground path is provided by the dark blue wire.

What I need to know is firs, does the dark green wire at the switch have power? If so, do the other two wires receive power when you actuate the switch?

Let me know.

Hi,

Yes, that should have power. It is a dark green wire. As far as the 14v, if the engine was running, that is normal.

Let me know if you got the right one.

Hello again.

Here is the location of the driver side power window ground in the splice back to help aid in diagnosis of this power window issue. I've attached the picture below and it's circled as #35 in red. Again this is attached mid dash on the A-pillar. Joe and I will continue to assist in this repair for you. Hope this helps and thanks again for using 2CarPros.

Hi,

I'm not familiar with the pic he attached, so I'll let him respond to that question. If you go back to the circuit breaker, is power out from it? If so, we need to check continuity in the dark green wire that sends power to that switch. There has to be a break at some point.

If you supply 12v to the green wire before the switch, does the window work?

Joe

Don't splice into a wire on the vehicle to get power. You can simply take power from the positive battery terminal straight to the green wire using a jumper wire.

Just be careful not to short the jumper wire from the battery to ground.

Let me know.

Hi,

If power flowed through the green wire and it worked, either we have a bad connection at the circuit breaker, or there is a break between the power source and the switch. One last check. See if there is continuity in the green wire from start to finish. Or, see if there is power at the circuit breaker.

Let me know.
Joe

Glad you found it!
That repair should be alright. Hope you put heat shrink tubing on it to help resist moisture. Thanks again for using 2CarPros and we hope you will use our site again in the future.
