Bob;
There is a small fan in there to pull air over the sensor that measures the
cabin temperature. I've never replaced one, so I can't enlighten you on the
repair procedure.

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".
Bob
