'08 4.8i - Pulsing pump noise at idle & low speed
I have a strange pulsating/whirling pump like noise that I think is linked to the HVAC system. It is only present when the A/C is off.
At idle or low speed it is a steady pulsing that seems to quicken with acceleration. Does anyone have any ideas or heard a similar sound? |
