96 camry door locks

Hi folks, can anyone tell me how to solve these two problems ?
i have a 96 camry and my front passenger side door lock will not unlock form the lock/unlock switch on the front passenger side door,i have to unlock it from the driver side lock/unlock switch,but if unlocked i can lock it from the front passenger door without any problem.next the right side back window will not operate from the driver side nor from the door itself.Help

For the passenger door lock problem it sounds like the unlock contacts on the passenger door lock/unlock switch are bad. Replace the switch.

For the back door remove the inside door panel and check for 12 volts dc at the window actuator motor when you activate the switch. If there's voltage replace the actuator/motor.

Thanks for the reply i will try troubleshooting it with your ideas over the weekend and let you know the results.
