Another way to tell is, the low pressure side line is always the larger of the 2

You Tube is your friend. You can pretty much find a video of somebody doing anything if you look hard enough. I was able to replace the trigger assembly in my rifle by myself after watching a video of somebody else doing it. It was a pain in the ass, and I cussed and yelled and screamed pretty much the whole time and my thumbs felt like I'd slammed them in a car door when I was finished, but I did it. And there was a time I would have never believed I was capable of doing such a thing.

It also helps if the guy in the video is some mouth-breathing idiot, because then you know if he can do it, you can do it. :D

BTW, I'm sure this particular operation is nowhere near as annoying/complex as replacing a trigger assembly.

Thanks guys. I think I'll just take it in.

He is a redcoat.

He's probably driving on the wrong side of the road which will make the ac blow hot air instead of cool.

You run the risk of possibly skinning some knuckles with this job, but that's really the worst thing that could happen....

Yep

I didn't want to get into a lot of details, have Donger give it a whirl and have to change his user name to "stubby or shop teacher," in the event things went terribly wrong.

LMAO

You English or French?

Neither.

its not really the "right" way to do it

If your A/C system is low on refrigerant and you purchase the refrigerant and just put the refrigerant in like most DIY types have done at one time or another, then no that definitely is not the proper way to fix this problem. It is only a temporary "fix".

I know im just a lurker but i used it about a month ago and its worked great,, i went from no ac to excellent in about 15 mihutes. I dont know if it is the right or wrong way to fix your ac but it worked for me and the 33 bucks was a lot cheaper than taking my car to a shop
