Well I have two seperate car trouble problems. When it rains it pours.
Problem #1- When turning my wheels all the way to the left my awd disable and anti-lock lights come on. I brought it to Advanced Auto to have it read and it came back with wheel sensor and O2 sensor. Well, they thought O2 sensor was a completely different problem, and the wheel sensor means ieither needed a new wheel sensor or bearing. So I purchased both and replaced it on the right font tire. Well, it didn't fix the problem. So I come to you for advice. I also checked the brakes and brake fluid and rotors and all looks good.
Problem #2- The only power window control that works and rolls the window down is the passenger side. Fuse checked out good. What would the problem maybe be?

For the windows, check for broken wires at the driver's side between the door and door frame.
As far as the ABS, I have seen issues with the wiring where the speed sensor harness goes from the control arm to the sub-frame being damaged.It has always been the R/F wheel with this issue.

I have attached the wiring diagram for your windows below, it will show you where to test for power.
See the guides below for testing wiring
