This happens when the door lock switch on the passenger's side goes out, but to be sure you can test the connection by following this guide and I have included the door lock wiring diagrams in the images below so you can see how it works and which wires to test.

It's not the switch. I have two brand new switches that work on the driver's side for both lock and unlock and soon as I put them on the passenger side it only unlocks.

It sounds like a broken wire at the door jamb which is common. Use the wiring diagrams above to test the connections and repair the wire as needed.
