1999 GMC Yukon

I wonder why GM would apply it to the accumulator, a part that would normally be replaced every time the system is opened for whatever reason (and the decal lost after the first replacement).

Because it's GM.

Agree that it's a dumb location.

I left the system under a light nitrogen charge as I had to leave town for few days, I will charge it when I get back home. I've got a 2000 3500 Silverado Dually crew cab which was my father's also, which I'm driving back to Phoenix this week, which will be next in line for some AC tune up. My dad bought this truck new and it has 56k miles. It has the same circle sticker (different specs) on the accumulator and the same piece of shit HT6.

I'll take some accurate temps and pressures so we can discuss.
