RepairPal Certified shops can diagnose and repair your 1994 Nissan 300ZX. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Low refrigerant (due to a small refrigerant leak over time) is usually the culprit. Also, a faulty condenser fan will fail to remove "heat" from the system and reduce A/C cooling. Your car just needs to be checked out. Thanks. david@apexautoaz.com
Thanks My trusted repair shop found $700 worth of trouble - replaced parts (as well as coolant),
Glad you got cold air!
