1999.5 Pathfinder auto-climate control whirring

I recently purchased a 199.5 Pathfinder (58K). It has the auto-climate
control feature. When the climate control is on -- at any speed or mode
-- there is a somewhat soft whirring/clicking noise comming from what
seems like the inside of the passenger-side dash. When the climate
system is off there is no noise. Any ideas what might cause this, or
what the fix would be?

Thanks.

Thats the blower motor - does the noise change if you manually change
the fan speed?
