Door Pin Problems

[Canadian 32]

Ok so since i got my car the door pin (the switch that says whether the door is open or not) on the drivers side has never worked. I had an alarm installed like 3 days after picking up the car and that was when i was told about it. But i have a new pin and have swapped the working one from the other door and neither fixed the problem. So I wanted to for peoples opinions as to what it may be that is preventing these from working? I was thinking of taking out some panels and tracing the wire to see if it is frayed somewhere or cut. Any thing helps, and thank you in advance!

I Asshume that the doors dont work with the interior light? Doesnt the door switch have to work together with the alarm for trigger etc? I would think you would not be able to disarm and arm the alarm with no working door switch?

the passenger side door works fine with the dome light and the alarm. but the drivers side works for neither, so the alarm is still armed.... but the siren doesnt go off since it is not getting a signal from it i am assuming. oh and its a viper 5000
