Q: Air not working

Hello. There are many components involved in the air conditioning system, and many possible points of failure. If no air is coming from the vent, you can consider the interior fan and its circuits. Cool or warm air when the air conditioner is set to max cool can point to a failure in an underhood air conditioning component. A simple fuse or low charge can halt performance. The system does need power, and a low charge situation can be caused by a failed seal. The belt drive system, air conditioning compressor and its plumbing, as well as the electrical system governing their operation, must be checked and maintained to prevent a future concern. Have a mechanic trained in the repair and maintenance of air conditioning systems inspect your entire AC system. Consider one of our experts here at YourMechanic.
