Section: 1D
Date: August 1990
Corp. Bulletin No.: 061202
Subject: INSUFFICIENT COOLING IN HIGH AMBIENT TEMPERATURES
Model and Year: 1988-90 R/V TRUCKS WITH AIR CONDITIONING C60/C69
TO: ALL CHEVROLET DEALERS
Some of the R/V model trucks from 1988 through 1990, either with or without rear A/C, may receive comments of insufficient cooling in high ambient temperatures. To address this condition a water shut off valve which operates during Max A/C and an insulator cover for the accumulator may be added. In addition, the refrigerant charge has been revised to increase air conditioning performance.
