07 Tahoe noise
When I start the Tahoe after it sits i hear a weird grinding noise coming from the fan area when you put it gear. Sounds like the fan is louder than normal too. If you turn it off and start it back up it sounds fine. Thanks in advance.

Do any warning lights come on? How long does the vehicle sit?

No warning lights, and it needs to sits for a couple of hours. Also you don't have to put it in gear, I was going off of my wife's description. When I did it this morning it does the same thing if you leave it in park.

"cleveland63b" offers a great suggestion. Another possibility is the A/C compressor trying to move liquid refrigerant through the system. The PCM may need to be reprogrammed with the latest calibration.
This is just a suggestion, not a diagnosis. I encourage you to have the vehicle inspected by a certified technician for an accurate diagnosis.
Please keep us posted.
