My old man and I just bought a nice little 97. It's his 5th or 6th S10, so he knows quite a bit about them and prefers them over other fancy trucks. They're great!! Anyhow...... living in Southern California, it sure would be nice if it had AC. Is it possible to install AC when there wasn't any to begin with? And how would I/he/we go about doing this? Thanks for your help. I'm glad I found this forum.
