Today I installed the smooth sails, saddle doors, vents, and third brake light from an Escalade EXT.  My 2008 black AVALANCHE  looks great. Question, does anyone know if the led third brake light is plug and play?  The break light plugged in to my Avalanche Wiring harness.  The problem is that the brake light does not come on when I hit the brake pedal. Taillights work.  Any help is appreciated.  Thanks.
 
I demand this thread be deleted until pictures are posted!!!  :kidding:  How long did it take to install?
 
It took about two hours.  But the the third brake light is not working.  I?m gonna have to remove it and test the light with a twelve volt battery.

Was wondering if you had pictures and or a website on where to get the smooth plastics for 2008 avalanche? I just bought a black 2008 av also and want mine to be painted as well
 
I doubt you will get a reply from original poster (if you hover over a member's name you can see when they last logged into this site, he was last on April 15, 2020.)
dboysen there are a mountain of threads dealing with restoring, painting and replacing the cladding with Southern Comfort kit or full replacement with Cadillac EXT smooth painted cladding. Since the AV or the EXT hasn't been made since 2013 the only place to find those smooth parts is used on this site, or a junkyard unless you get lucky and find a dealership with new old stock.
 
It should just be plug and play. It was on my 06, best update I've made this year.

Look on Ebay or at junkyards. The covers are readily available and will be painted since they were on a truck. Try to get a set if you can.

Mine were from an 04 and fit perfectly. The only mod I had to do to the set was to cut a hole for the backup camera. The donor truck did not have the tailgate camera.

Do you know maybe what I would search for on ebay? I have tried looking but not really any luck. Thanks in advance
 
Yup picked my set up off of eBay and it was originally white so I had to have it painted, but I've seen them listed on Craigslist and Offerup. I'll post a startup video if you'd like. Nothing special just a Flowmaster 40 series the previous owner put on, I just added a larger exhaust tip cause the old one was all rusted.

Like this one on Offerup, could see if they are willing to part out the cladding pieces?

Damn! This is the next mod after I fix the transmission, did you have to get them of the same year/gen ext or do they all work? I found inner and outer sail panels and 3rd brake light I was wondering if they will work with the avalanche sale covers and I will just paint those
 
You’ll need the complete set including the side doors the parts are the same except for the tailgate. Just did my 07, got parts off earlier 04. There all the same except tailgate.

What's the difference in the tailgates?

The tailgate lip on the 2007+ is a little longer than the 1st gen. Chevy redesigned the whole body in 07 but they looked for ways to keep the avalanche cost as low as possible so they reused as much of the bed and trim panels as they could. If you compare the lights and tailgates you see they are shaped differently to blend into the new body style. That required a new trim part for the top of the tailgate.

With that said....the 2007 Ext tailgate spoiler I bought will fit my 09 Av?
