Bulletin Summary
TECHNICAL SERVICE BULLETIN: SERVICE ACTION: A/C COMPRESSOR REPLACEMENT (SA632) - This bulletin provides information to address air conditioning performance issues reported on certain 2025- 2026 model year Carnival (KA4) vehicles produced between December 1, 2024, and June 12, 2025. Customers may experience intermittent cooling or insufficient cooling at low blower speeds. The cause may be excessive clearance between the compressor piston and cylinder, which reduces refrigerant compression and results in inconsistent or weak cooling performance.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
