My son has a 1998 Volvo S70 GLX and I'm trying to identify the attached part (in pic). Also does this part appear to be complete? I'm asking because there seems to be a control screw in the middle that sticks out pretty far from the part which suggests there may have been a cover or another piece to this part.

Thanks in advance,

That would be the alarm horn

 

Thanks for identifying the part. Now I know why there is no sound when the 'alarm' is activated....
