03 Excursion Air Conditioning help

[MotleyCrueCab]

I have an 03 excursion and need to replace the rear ac line, as it is leaking. Does anybody have a diagram or any advice...

Thanks

I think the lines run along the outside of the body along the passenger side frame rail, then up into the rear air box. Is it indeed a bad line, or bad o-rings in the the joints? Here is a link to an article on our sister site www.superdutydiesel.com. It is for an upgrade to insulate the lines to help with cooling. It has pictures of the route of the lines.

I have not worried about the upgrade, and mine will make it cold in the truck. Yesterday here it was 95 - 97 degrees, not too humid, just way early for those temps here. The kids asked me to turn up the heat while we were out driving in the heat.
