TO: ALL CHEVROLET DEALERS
Some 1982-84 Camaros may exhibit the condition that air will blow only from the defroster outlets. This condition may be caused by a loss of vacuum to the A/C control or the A/C mode doors. Specifically this condition may be caused by a pinched vacuum harness input (violet) line near the A/C control. To repair this condition, remove kink from the violet line of vacuum harness and re-route to prevent recurrence.
If this procedure does not repair this condition, determine other cause for loss of vacuum according to Service Manual.
