Like every electrical component in your vehicle, multiple factors can be contributing to a climate control system issue. Faulty vents, a broken interior temperature sensor, failing fan motors, degraded fan relays, a refrigerant fuel leak and an insufficient amount of coolant in the engine.

If your vehicle’s climate control system is not turning on at all, it may be a problem with the system’s electronics. The fuse may have blown or an issue with the wiring may be present. Electrical issues such as this may also be caused by a failing battery.

Manual Climate Control

Manual climate control systems operate through a series of cables, vacuum hoses and airflow control doors. Users manually adjust the system to increase or decrease the amount of airflow. Very few electronic components are used in manual climate control systems, making them less complicated to repair.
