2009 Patriot power windows not working

I am working on my mother in laws 2009 Patriot. Her power windows stopped working completely. I checked all the fuses which looked ok, even though none were marked as being for the power windows. I then took the door panel off and found the Pink/Brown wire that the wiring diagram lists as coming from the IGN SW OUT. It did not have 12V on it when measured with my meter. I created a small jumper wire and came off the power mirror switch and the windows started working. It makes me believe there is a short in the wire somewhere or maybe there is a relay that is bad.
Does anyone know if the power windows use a relay, and if so, where the relay is?
I have attached the wiring diagram I found on the internet.

There is no power to any of the windows at all. I pulled the power module out of the engine compartment and am trying to find the wire now to test to see if I have a break in the wire between the IPM and window switch.

Thank you all for your help. I figured it out. The wire was broken inside the boot that goes from the door to the car (right below the door hinges).
I figured it out by putting a meter between the TIPM and the door panel switch.
Once I saw there was a break, I started testing individual segments, (TIPM to door boot, door boot to switch). I ended up splicing in a new wire and it is working now.
For those who want to know, I took a photo of the bottom of the TIPM and the door switch and circled the 12V power lead. It is the Pink/Brown wire. It runs from the switch all the way to the TIPM.

You are welcome. Even though it is my MIL's Jeep, I know she appreciated the free repair, and I certainly appreciated having a community I could quickly go to and get help.
Thank you!
