Windows and door locks not working

Hi,

I went through the wiring schematics for both the windows and the door locks. Both have different power supplies, so I don't think that is the issue. However, I did find one item that involved both. Both are grounded at the same point. Take a look at the two attached pics. The first one shows the ground for the locks and the second is the ground for the windows. That is what needs checked. I suspect that is the problem. Also, note that both circuits have a splice location, so make sure that is okay as well.

Let me know what you find or if you have other questions.

Take care,

Joe
