More knowledgeable people can probably tell you how to test the
refrigerant level, but it seems to me that after 16 years, it may need
to be recharged. From what I've read/heard about other vehicles AC
systems low R134 or R14 (asI recall, 1990 was _about_ the time of the
mandated change) may cause this problem. Sorry, I don't have more
information, I'm just watching this group as I may buy a Chevy/GMC in
the next year.

Hi, All.
My Silverado (with only 72,000 miles) A/C is continuously cycling on and
off in 4-6 second increments regardless of interior temp. Can someone
point
me in the right direction to troubleshoot. Thanks.

I have a 1990 Suburban (200,000+ miles) and while I can't diagnose your
problem, I can tell you that you have an R12 system (unless it's been
converted).   If the system isn't low on freon, it could be a bad
pressure switch.
