Z88 ????

[Wayne2]

I have a Z88 on the code sheet in the glove box of my 2003 GMC. I can't find a reference to a Z88 in the RPO codes. Does anyone know what Z88 is?????

On the same note, I would like to know how to decode all of that stuff in the glove box. Where do I look?

Metz to your left at the top of the gm-trucks page look unde the bold main. There is an option (7th down) titled RPO codes. Click that

The code Z88 simply means it's a GMC.
