Power windows not functioning

Hi,

I attached the wiring schematic below in pics 1 and 2. I overlapped them to help you follow them.

Now, first check to see if there is power out from the violet wire at the main switch when you select the up direction. That is what powers the window up. The power is sent via the violet computer data line to other windows. See attached. Remember, the power to raise and lower the window is controlled by reversing the polarity of the power supply. So, if it works down, that tells me that the wire isn't broken, but leads me to believe the switch is bad.

Let me know what you find.
Joe

Thank you.

You are very welcome. Let us know if you have any questions in the future.

Take care,

Sir, for the power window can I get system description for it?

How it supposed to work.

All power window switches have power and ground when the switch is pressed. how does it communicate with the ECU for the Motor to function?

Apart from the ground and power, what else can be checked for?

Hi,

It's straight forward. Power is supplied via one of the two wires to the motor. The opposite wire then functions as a ground. If you have power and ground, the motor will work unless it's bad.

Are you checking for power at the motor itself?

Joe

No, I am checking the power at the switch.

No problem. Go to the motor and check to see if power is there. Let me know what you find.

I will watch for your reply.

Hi,

This post was in my replies which usually means you had an additional question. Did you need anything? Nothing is listed.
