The rear AC in your 1996 GMC Suburban may not be blowing cold due to several reasons, including low refrigerant levels, a malfunctioning compressor, or a clogged cabin air filter. Additionally, leaks in the AC system or issues with the rear AC controls can also prevent proper cooling. It's best to have a professional inspect the system to diagnose and resolve the issue effectively.
