that is most likely your abs control module locate your 60 amp abs fuse under the hood and remove it if the noise stops you need to replace your control module

SOURCE: how much can Yukon SLT tow?

Towing capacity: 2,041kg (4,500lbs)

SOURCE: Yukon dvd player will not continue playing on rear screen

my 2007 tahoe does the same thing. i ordered the remote control to see if i can just use the Power button on the remote to turn on the Rear LCD screen without ejecting the DVD and re-inserting

Any GM car dealer can cut a duplicate key for your car for about $10. You have to show them a picture ID, and the car ownership (TITLE). This key, without the transponder chip, will let you unlock the car but won't start it. Just tell them that you need a plain car key, without the transponder chip.
