Fuse number 23 in the passenger compartment box is blown. It caused the following devices to stop working: Door lock switches (but not the locks), Interior lights, radio lights, A/C climate control, overhead console quit.
Power door locks may stop working due to several reasons, including a blown fuse, a malfunctioning power lock switch, or issues with the door lock actuator. Wiring problems, such as frayed or disconnected wires, can also disrupt the electrical connection. Additionally, a dead key fob battery or problems with the car's central locking system may contribute to the issue. Regular maintenance and prompt diagnosis can help address these problems.
Yes, a bad fuse can stop electronic door locks from functioning. Many modern door locks, especially those that are electronic or smart, rely on electricity to operate. If the fuse linked to the lock's power supply is blown, it can cut off power, preventing the lock from engaging or disengaging. However, traditional mechanical locks would not be affected by a blown fuse.
The fuse for the power door locks is labeled courtesy or "crtsy". The only way that the power door locks would stop working altogether (no switch will trigger any door lock) is by blowing a fuse or possibly cutting a main wire to the door lock system. If somebody has worked on your electrical system or if you have had a car stereo or alarm system installed this would be a lickely scenario.
The drivers door window switch is the master; all power runs thru it first. check the breaker if that is good, I would pull the switch at the drivers door and test both sides of ot; it may just be a loose connection. Power locks are a unrelated/seperate circuit.

The power door locks and the radio in a 2000 Dodge Stratus SE may stop working at the same time because of a blown fuse. Another issue may be faulty wiring causing a problem for one or both of the issues. Both of these problems can be fixed by taking the vehicle to an automotive garage or shop to be fixed by someone who has experience in these vehicles.
