Passenger Door won't Lock

[memevertical]

Yesterday I wanted to see if my Dimmer Knob was correctly connected, so I took of the dashboard really quick, and put it back together.

Now this is the problem, no the passenger door wont lock, this is what happens:

If the driver presses the LOCK button, it locks every door but the passenger's one.

If the passenger presses the LOCK button, it locks every door but the passenger's one.

If I use the Alarm Remote Control and hit the Lock/Unlock button it works for every door but the passenger's one.

Any idea what this could be?

Thanks.
