I'm gonna attempt to recharge the AC with the R-134a kit I bought. Where is the low pressure port I connect to? I see 2 different tubes with ports behind the radiator. The fatter one is father from the radiator and the thinner one is between the radiator and the fat tube. Is it the fat tube?

Th high pressure side is attatched to the condensor and the ac compressor, the low pressure is the other 1, so attatch it to the low pressure.

I knew that... I just didn't know which of the two was high and which was low. But I figured it out. One had an 'L' and the other had an 'H'. I just never noticed.

But anyway, I just recharged it and it didn't work. All the R-134 in the can went in, but the air still isn't cold. I used the included guage to check the pressure before recharging and the pressure was already at the 'too high' area. So I loosened the guage and let a lot of air blow out until it was at 0. Only air came out, no R-134 stuff. Then I recharged it and now it's back at the 'too high' area, but still blowing hot air. Anybody got any suggestions before I blow $100 at a real AC recharge place.

is your AC compressor working?

It seems to be going on when I press the AC button because you here the engine sound change. But other than that, I don't know how to check it.
