Volvo: 2001 s60t5 electrical problems, door locks, electrical problems

Question
It started with the door lock (drivers side) that would not automatically lock - I had to manually turn the key and pray that it would stay locked.  Now, the interior lights, the sunroof, and all the door locks will not operate.  What is the problem?

Answer
Caroline,
There is a problem with the electrical module that controls all the interior items. It might need a new download to set it back on track. The dealer will have to plug in and read any fault codes and purchase the download if that is determined to be the fix.
