2007 3.2 AWD 32k<p>I'll start with the issues:<br>(1) Occasionally the front passenger door will not lock with the remote or autolock, but the blinkers blink their all-ok confirmation. Today this happened again, and pressing lock again did nothing, so I opened the door setting off the alarm and tried it again. I can't figure out why the car would think it is locked- I thought if a door failed to lock, the lights would not flash. Is this just a servo issue or something related to the network?<p>(2) Has anyone else had an issue with random popping sounds coming from the ceiling trim? It is not a creaking/flex sound, but a crisp pop that seems to happen on even the smoothest roads. Did Volvo do anything about it? <p>Now for the questions:<p>How do the door panels come off? The tweeter in the drivers' door has something loose in it that the dealer cannot replicate of course, and its driving me crazy. <p>I had a V50 loaner and was impressed by the ability to program certain options like length of time for Approach Lighting and lock/unlock light flash. Is there any way to access those options on our cars? Thanks!
