Anyway, yes, the front AC works fine. Since it was cold this morning, I tested the heat, and I do have working front and rear heat, thankfully, that will be nice this winter...
So, the front AC works, and surprisingly, it works best at highway speed, despite reports here on the forums about how highway speeds will make it stop working, due to the air pressure problem that you're meant to solve with an elbow... joint? I think that's it, the pipe thing.
The rear AC however, does not. It doesn't blow hot air, it's just simply not cold, like a fan you'd sit on your desk, it just blows the air. Also, there is a constant hissing from the rear when the AC is on, and it increases and decreases with what I assume is the fluctuations of the AC system.
It just confuses me, because... if it was a leak, a leak bad enough to hear the hissing, surely it would've leaked enough to stop my front AC from working, right? I read somewhere else on the forum (perhaps it was you, moose...) that if you're a bit low, the rear will stop working first, and all you need to do is add refridgerant to get it working again.
Normally, I would say something along the lines of "It's not that important because it's usually just me", however, our 07 chrysler van is once again broken, so I'm the family transport for now, and since me and my brother sit in the front, my parents aern't too happy with the nonfunctional AC, so I'm either hoping that it's an easy enough fix for me and my not-so-good-skills to fix, or that we can at least find out what's wrong so I can take it to a shop and save them from having to diagnose it themselves....
