My r32 gtr air conditioning didn’t seem to get cold this first summer drive the other day and I was trying to do some research and some looking around the car and found this sticker. And these lines. It appears there’s a 134a sticker confirming the previous owner may have done a swap, but the lines don’t look like a 134a connector. What are we thinking?

Drove the gtr for the first time since last summer and tried the AC. I didn’t feel any difference between it and the regular fan.. it worked well last summer and before since I’ve owned it. I know the r32’s originally take the r12 Freon, but I noticed this sticker on my radiator. I’m assuming this means the previous owner did a conversion? Is this now something as simple as recharging it with some 134a?
