There are two power supplies we need to check. One is a fuse and the other is a fusible link. A fusible link functions the same as a fuse, but it looks like a regular wire. If you look at pic 1, it shows the fuse and its location as well as the fusible link.
To check the fusible link, you have two choices. One is to simply see if there is power from it on the body control module side. Or, disconnect the battery and check it for continuity to see if power can flow through it.
Next, I attached a two additional pics showing the entire wiring schematic related to the windows and locks. If you find the fuse and fusible links are good, then you need to check for power to the switches in the driver's door. If there is no power, then there is either a problem between the BCM and the switch or the BCM has failed.
Here are a few links you may find helpful when checking things:
Please note that pics 2 and 3 are from the same page. I had to cut it in half to make it readable. I did overlap the two so you can follow it.
Let me know if this helps or if you have other questions.
