the entire center part of my dash had turned into it's own floppy piece that continually flapped going down the road for months, so i decided to try and repair it this weekend.

i don't feel like spending ~$500 to get the two dash pieces, so i opted to try and epoxy it all back together.

i used two packages of gorilla glue two part clear epoxy, and it seems to be holding up fine.

some things i wish i knew before i got started:
- i've never pulled an air bag before, and was not familiar with the harness. i had to pull the red "pin" from the top of the harness, and then you can unclip it like any other harness.
- there are many different style harnesses you have to unclip (i'm mainly used to the square/rectangular ones), so i had to take a break here and there to find out how to unclip some of them.
- i should have taken a piece of cardboard and put the screws into a map of sorts so that i would have been sure that i put all the screws back in. i may or may not have had extra screws when i was done..... :/


first thing i did was to put my truck in gear (d), but then i wasn't able to take the keys out. good thing i didn't need my keys during the process. then i pulled the negative cable off the battery.

i followed this video that i found through another post on this forum:


the rest is just screws and bolts - somewhat straightforward if you watch the video. i'm sure there's an easy way, but i had to manhandle the dash to get it out of the truck. i'm surprised it didn't break any more just trying to get it out. i wish there was a video tutorial showing how to take out the dash and put it back in. i finally was able to manage it though.

once i got part way in to the removal, i found out just how bad the cracks were.

top left part of passenger airbag:
full


top right part of passenger airbag:
full


right of gps antenna:
full


top left of center speaker:
full


above/behind instrument cluster:
full


lots of epoxy was used around the airbag hole. there was a lot of plastic missing:
full


the crack next to the gps antenna took a lot of epoxy - it never did cure just right. had to use zip ties to hold the dash in place while it cured:
full


again, this single piece is huge. glad my son was able to help me get it in and out of the truck:
full


for a diy'er, the inside can look a little intimidating once the dash is out:
full




all in all, i'm glad i tried it. it took me just over two hours to remove, a little over 2 hours to install, and a 2 hour break in the middle to apply epoxy, let it dry, and make lunch. i'm sure when i finally decide to spend the coin and replace it altogether that it will go a lot quicker. any competent tech should be able to do the swap in half a day if a novice like me can knock this out.

the end result is fine for me. there is some spots on the surface of the dash where the cracks don't line up perfectly, and some other spots where the clear epoxy came through. you'd only really notice if you know what to look for when it comes to cracked dashes.

i thought about hot stapling like the youtube video shows, but that's another $100+ to get a decent hot stapler. if i'm spending over $100 then i'd just buy the replacement dash parts. the good thing is with my el cheap-o method, the cracks no longer rattle of flap - which was my end goal.

i guess i should probably get some "after" photos as well. i'll do that in the next day or two.

Thanks for sharing.

Crossing fingers that the dash on my '08 continues to hold up and doesn't crap the bed.

no worries. let us know if there's a good way to get the stupid thing in and out easily - or if i'm just an idiot and didn't move the steering wheel correctly or something. :p

Thanks for sharing.

you never know. as you can see mine was completely severed under the smaller forward dash piece. :(

How long had the dash been showing signs of failure prior to your work to repair it?
In other words, do they clearly deteriorate bit by bit over time or do they look fine and then one day they just crack wide open with no advance signs of failure?

Are you planning on adding any reinforcements before install? Especially in the area where the cracks are. Plus, I heard if you use rubber/silicone washers on both sides of the dash at the attachment points and do not torque the bolts all the way, it will allow for the plastic to move and not crack.

No. I might use some rubber on the bolts then...

On the cracked dash FB page, there is a guy who fixes them or installs new ones and he mentioned the rubber washers on all his jobs. He is pretty convinced that it is the fact that GM affixes them too tightly and it is the stress that cracks them.

@papaman , thanks for the post. I most likely will be pulling mine out and fixing the fixes that the dealer did before I purchased mine. His repairs are starting to fail. Still on the fence of wrapping mine in marine vinyl while it is out.

forgot to mention, but underneath the massive split under the top left portion of where the passenger airbag sits, i did reinforce the area. i cut 0.5" x 4" strips out of some 3" SCH40 PVC pipe i had laying around. wasn't sure what best to use for reinforcement above the instrument cluster, so there's multiple layers of epoxy. i'd apply a bit, let it cure, then apply some more, repeat.

mine failed a little over time. parked in the sun one day at work many years ago. i got in to go home, heard a loud pop, and the dash above my instrument cluster cracked. then there were cracks around the airbag, then an entire piece above the dash fell out. it has definitely deteriorated dramatically as time went by.

@NathanJax if your truck has the center speaker i would recommend putting some sort of reinforcement around it, maybe a rigid foam like a cut up car washing sponge? mine currently 'bounces' up and down a little when it's hot out, i reeeaaally wish it was supported better. I might try to open it up and get something in there before it cracks again and i stroke out...

to OP, i'm impressed you got it in and out that quick. my truck was at the chevy dealership for 3 days when i got mine replaced o_O

I don't own an 07 up. But if I did I would think about putting some reinforcements in and dynamat it to help hold together. And I like the rubber washer idea too. I have read all the posts on this issue and from what I gather the plastic they used is too hard in combination with being too tight and in the sun all day!!!! Not great combination.

I'll tell ya I'm impressed, how hard is to remove the passenger airbag? I think I can fix mine without removing the dash, just the airbag.

from a procedural standpoint, it's not too difficult. here's how i would do it if i were in your shoes. follow at your own risk!
- disconnect the negative terminal from your battery and wait a while in case there are capacitors that need to discharge.
- if you are sitting in the driver's seat, begin to pry out the panel with the center air vents. those vents are connected to the button panel to the left of the vents, and the long plastic panel that runs between the center vents and the air vent by the passenger door. careful taking it out, it's not connected very well and feels flimsy.
- on to the passenger air vent: there is a single screw holding it in place on the top left. you can pry the entire vent out after taking out the screw.
- on the youtube video link i posted, go to the 13:38 mark and you will see the four bolts that need to be removed. those are the only ones holding in the airbag. you will want a long extension for your socket, and be careful not to drop the bolts!
- now you can pry the airbag's plastic cover out of the dash starting with the part closest to the passenger seat, and the entire assembly will come out. it will need to come towards the inside of the vehicle at an angle to get it out.
- follow the wires and you'll see a big yellow connector with a red plastic pin. pull the red pin and then disconnect the plug (you can duck while doing this - i know i did).

thanks! if a total noob/beginner like me can do it in a few hours, then the dealerships are screwing everyone over if they take more than half a day.

Nice work and thanks for the tips. Mine just started cracking in the same spots but wasn't bad enough where I had to take the dash out. I used some of this JB plastic bonder and hope it stops the cracks from spreading.

Took 2 hours this morning, but that includes wiring up a USB outlet. Watched the video before hand for tips, and just a side note I do car audio/video so I'm comfortable doing stuff like this. It'll probably take most people a little longer...

Got any after pics yet, OP?

The dash on my wife's Tahoe is not as bad as yours seemed to be, but I've been contemplating between trying to fix it or just getting a DashSkin (the one that goes over the whole dash, not just the top). http://dashskin.com/2007-2012-tahoe-suburban-dashboard-cover-w-o-dash-speaker-rear-dash-only.html

Kind of leaning more heavily towards the DashSkin due to the fact that I'm pretty sure me and my fat fingers would be breaking bunch of other stuff while removing the dash for repairs. :banghead:

Decisions, decisions...

bottom line is that it still looks like crap, but it doesn't rattle/flap anymore, and it didn't cost $500.

when i feel like spending the money i will definitely buy a new replacement, but until then i'm glad to have fewer rattles when the sub hits. i looked at the dash skin, but if i'm going to put any money into it, i will just pony up the coin for a replacement.

oh - my fat fingers worked just fine. don't let that hold you back. :)
