I bought a 1996 Buick Skylark GS with a 3.1L V6 back in march of 09, and my dad bought it back from me in January of this year so that he could fix it up. One of the issues is that the A/C doesn’t work, and the defroster doesn’t work either (which means that it can’t be driven in the rain, otherwise the interior fogs up terribly).
We’re finally getting around to getting it fixed so that I can get a job and get more camera equipment and various other items that I desire, as well as helping out with family bills and such. The only problem is that we can’t identify which of these little knobs in the pictures below is the low pressure valve. We’re hoping that it’s the red one, because the blue one would be a pain in the rear to access.
Here are links to the pictures:

The port with the red cap is the high side, and the port with the blue cap is the low side.

Well that just figures. Thanks for the info.
