I know my '04 Chevy Trailblazer EXT had the 3 button programable garage door opener. I just bought a '14 Chevy Suburban LT that does not have those 3 buttons but I was told that it had the capability of programming the garage door. Is that true and if so how is it done? Thanks

 

Would think that's in the owners manual

 

To the best of my knowledge, if you don't have the 3 buttons, you don't have the Universal Remote System. You might check with your local dealership and see if it is an install-able option, I don't see why it wouldn't be.
You will need the different console bezel that has the buttons, the GDO and wire harness...

 

I thought the programmable garage door opener was standard equipment on all models.

 

Thanks. I think you're correct.

 

I bought a used "14 Suburban with a full BlueTooth. How do I delete the info if I do not know the numbers or names?

 

Your owners manual has that info on page 7-51..

 

I'm in the same boat as the OP. So are we saying that I all we need to do is buy the new overhead bezel with the 3 buttons and we're good to go?

 

I would pull your current overhead console and see if there is a wire harness there for the GDO

 

Here is link to when I installed my dash cam and used power available from the harnesses and it shows what the GDO module looks like
