Hi Y'all,

This noise is not (I don't think anyway) connected with the blower 
for the AC.  Instead it is a high pitched cricket-like sound which 
seems to come from the little (~3/4" square) dash top vent after the 
AC has been running for quite some time - usually an hour or 
more.  The noise goes away if the AC blower fan is slowed way down or 
turned off but I really don't want to have to disable the AC for the 
sake of a little quiet.

Is there a tiny blower in there which moves cabin air over a 
temperature sensor or something like that?  Anyway, what's the repair 
procedure?  Please don't start with "Step 1 - remove the dash".
