Having problems with your 2007 Chevrolet Tahoe ?

I have a Chevy Tahoe 2007 that i bought used. As soon as i took it home i could hear a whistling noise when i turn the climate control on. If i open a window just a little the sound goes away. It looks to me that its negative pressure created by the climate control and when air is entering the cabin it is whistling somewhere. Any help would be great since the dealer where i bought it already had the car for 3 different occasions and still didn't fix it.

Answers :

Turn on the climate control and walk to the rear of the vehicle. There are small vent holes in the back window to release positive pressure air. Check to see that they aren't partially blocked with dirt or wax. They are small holes, so look carefully.
Check ur door seals usually by the back door area with the truck running and the climate system on walk around truck and listen for air or use incense and move it around the gaps of the doors the smoke from the incense will **** in where there is a gap problem with a seal if seals are good there is also a cabin filter inside vehicle possible air leak or even clogging filter would hear noise on pass dide behind glove box
