The black one is GM Genuine 15055342, white is 15055343. Don’t buy the Dorman ones, they don’t last from what I heard.

White is driver side. They have different angles where the rear lines connect. Not sure if they’d work if you reversed them.Which color goes on which side?

I removed the rear quick connects. They weren’t as brittle as the fronts, maybe because of no engine heat. But there was no way they were coming off without just destroying them.
I don’t think I can do without elbows there, the hose would kink. I can’t find those on any GM parts site, so I ordered some Dorman ones, 1 day prime. They’re easy enough to access so if they break in the future they’re easy to replace.

Do you have enough slack in the lines for the new connectors?

Yessir, there’s enough to get er done. I ordered some 1” spring clamps to hold them hoses on too. I hate screw clamps.

I started on the rear hvac unit today. Fist thing was removing the old refrigerant hard lines. I know the new kit says you don’t need to remove them but why wouldn’t you? Hopefully they’ll fit in the original clips. I will say if you were to use hard lines to replace them with it would be a lot of work. There would have to be a bunch of stuff removed including the running boards, at least on a Denali. There’s 2 types of clips, neither are too hard to release. I ended up cutting the lines into several pieces to get them out. After that, and having the heater lines removed, it was fairly easy to remove the unit. There’s 2 10mm nuts on the underside and some harnesses and screws on the inside, accessible after removing the panel.
