why do my power door locks, windows and side mirrors not work?

Thanks, will check the fuses.

Were is fuses located

Fuses are located under the back seat near battery. However, it may also be caused by corroded connector under driver’s seat. So, if fuses are ok, take out driver’s seat and lift up carpet to check the connector.

I replaced the passenger door module and no change.
