Why the defrost may not work in a 1993 Chevy Caprice Classic could be because the heating core is out.
The most common cause for the defrost not properly working is a malfunctioning blending door. The blending door might be stuck halfway open. This would cause the defrost not to work unless the fan is on high.
It would depend on which defrost system is not working, the rearview mirrors, back window or front window.
