Q: Air conditioning doesn't work

asked by on January 25, 2016

The passenger's side air only blows warm air, while the driver's side is cool. Is this caused by a blender door issue?

Modern cars have complicated HVAC systems that are heavily controlled and monitored by the car. The most likely cause is a blend door or a temperature control door has failed. A qualified technician would be able to diagnose the issues with your air conditioning.
