Ok so I started having door issues shortly after replacing car battery. I am hoping to find solution to repair or fix, any help or tips are greatly appreciated.

1st issue is that my rear passenger side door lock as well as handle (comfort access) does not work. Power lock on the door neither responds to power lock button inside the car nor remote control as if power is completely out on that door. The soft door close does not work either.

2nd issue is that comfort access open on driver's side door stopped working while comfort access door lock works perfectly fine. What could possibly wrong with the driver's side door?

Thanks in advance.
