My old truck is a 2001 Sierra 1500, has several small things wrong with it, and I don't use it often anymore, I will get some dye and see whats leaking if I can get off my butt.
Nice write up Scott, almost have me convinced that I could do this, how did you determine what to replace. Did you keep all the old lines and stuff. My ac hasn't worked in years, I used to get by adding a can every summer but that became twice a summer. It might last a day or two now.
