As for the warranty, it depends on your sales details witn your dealer. Normally a 2007 model is already out of warranty.

Most GMC and Chevys have a bottom plastic bracket holding the battery into the battery tray. All you need to do is get the correct socket and a wratchet with a long extension to loosen and remove the battery.

there is usually a small bolt that holds it in place with a rubber block the rubs along the bottom of the battery. Take a flash light and look for the small bolt at the base of the battery,,You need like a 1/4" drive socket with a 6-9" extention on the socket to reach it..Just unscrew the bolt and the bolt and the block will come loose,you just lift it up and out of the way. Remove old battery and reinstall new one in reverse order.

try to look under it for the cheap *** piece of wire or spring they use to connect the lock levers to the handle.

need to know if it is a hid or regular light as the procedures are differnt

This is an easy fix that doesn't require any tools at all.
Raise the hood and look directly on the top of the headlamp assembly.
On each side, there's a rod. Swing it out and pull it up and out and place to the side for now.
Next, grab the assembly and pull it forward and you will see the bulb connections in the back.
Reverse the procedures to reinstall the assembly.

Is your Denali a 4 whhel drive or all wheel drive?

open your hood and it should be right behind where the light is you will have to twist it and pull it out there is only one light for the low/high beams

just call the dealer most of them will tell you

It is an easy change for you and yes I also hate people scraping my pockets as well...........Hope this helps.

If you replace the BCM on your own the vehicle will not start.The BCM has to be reconfigured per the RPO codes for your vehicle and per your vehicle identification number.This can only be done by a dealer.It takes a special scan tool and it has to hook up to a special computer at the dealership that has all that info for your vehicle and it reprograms the new Bcm.You can not use a used one because it will have the info from the vehicle that it came from.Hope this helps.Good luck.
