Some say normal, some say water pump is on the way out. It seems that when I turn off the climate control system the fan does not do the loud roaring. Anyone have any ideas? Thanks.

impending water pump failure.. get it fixed before it leaves you stranded on the side of the road. |
Yup water pump and thermostat... same thing happened with mine. $800 later problem fixed.
