Chevrolet Repair: 1988 Suburban w/ an A/C problem, autozone, repair manual

Question
Is there a book or website that shows a complete diagram of the a/c system.

Answer
You can try going to www.autozone.com, they have some limited repair information on that site. You can also go to www.eautorepair.com and purchase a one day, week, or year subscription for the repair manual and bulletins for your specific vehicle.

www.alldata.com sells subscription also but a year is the minimum. if you work on your vehicle all the time it's not a bad idea to buy a year or more subscription. since I'm now retired from Chevy I use the ALLDATA site for my cars.
