Why is my truck’s AC not blowing cold air?

Common reasons include low refrigerant, leaks, a failing compressor, or sensor issues. HVAC systems can also stop cooling due to electrical faults in the climate control module or wiring harness.

Can a bad HVAC system affect safety?

Yes. A faulty HVAC system can cause poor defrosting, which limits visibility and violates safety regulations. In cold climates, heat failure can also pose serious health risks for drivers.
