Problem with power door lock.

I recently bought a 1995 SVX, and just noticed that the passenger side power door lock isn't working. I have the keyless and alarm entry setup; this is how I found out it doesn't work. The driver side works just fine. I was sondering if anyone out there would know what I should look for. I want to fix it myself if possible. Should I start by removing the door panel and looking to see if any internal damage has occured? I would be very pleased if anyone could help me.
Thank you for taking the time to help a fellow (new) SVX owner.
