I have a 2002 S80 with 110K miles. The door locks close using the button located on the inside of the doors, but they do not open with this button on the second push as they should. The key fob works correctly. Do I have a bad relay? Anyone have a schematic and a suggestion on how to track this one down?

You could have a bad switch or contact. Can you pull the switch and check the connections and spray with an electronic spray?

Yes I can - the question is which switch to check. Since both the front door locks on the arm rests don't open the door I am thinking it may be where the relay is? Anyone know how I can track down which relay to remove and clean?
