Could a blown fuse cause the air conditioner in car to stop working?

Yes, a blown fuse can cause the air conditioner in a car to stop working. The fuse protects the electrical components of the AC system; if it blows, it interrupts the power supply to essential parts like the compressor or blower motor. Checking and replacing the fuse is a simple troubleshooting step if the AC is not functioning. However, if the fuse continues to blow, it may indicate a deeper electrical issue that needs to be addressed.
