Check your fuses.
Check the fuses.
Start with checking for blown fuses.
There is a Relay for the Power Door Locks, which I purchased today from Checker Auto parts, but I can not find where the relay is located. I am assuming or hoping that it is the Relay for both the Door Locks and Power Windows.
If the power windows and locks are not working on a 1998 Dodge Durango, it could be due to a blown fuse, a malfunctioning power window switch, or a problem with the door lock actuator. First, check the fuse box for any blown fuses related to the windows and locks. If the fuses are fine, inspect the switches and wiring for any signs of damage or malfunction. Additionally, ensure the vehicle's battery is in good condition, as low voltage can affect power accessories.
Remove the power locks and windows fuse you will loose power for your windows also

It can be your battery, when it doesn't have enough power the computer will not allow you to use power stuff. It can be also one of the relays which are responsible for stuff like power locks, power windows and so on.
My door locks stopped working and I pulled the IOD fuse and reset it back after starting the vehicle. Now all locks work great to include the remote process. The IOD is mapped on the lid of the fuse box.
