SL55/63/65/R230 AMG: AC low pressure port
Driving from Florida to NY as we speak. The AC is not blowing ice cold air..but just tiny cold and it’s hot in the car.
i want to recharge the AC if it’s the issue but I can’t find the low pressure line. Is it the top or bottom one?
Thanks
If it starts cold then gets warm, I doubt it's just low on refrigerant. There's probably something else going on. Would suggest taking it and having it actually checked out rather than just pumping freon into it, but if you're on a road trip I understand the situation there.

So this is the low pressure?
I hooked it up to STAR. I got a 1075B communication error with the AC. Perhaps a sensor.
will keep looking into it
