Can a Blown Fuse o r Faulty Relay Cause My A/C to Stop Working?

Yes! If the A/C fuse o r relay fails, the compressor won’t turn on, resulting in no cooling. Symptoms include:

A/C not turning on at all
No sound from the compressor clutch
No airflow even when the fan is on
Checking the fuse box under the hood for a blown fuse and replacing it can fix the issue.

Yes, a blown fuse o r a faulty relay can cause your Toyota Camry’s A/C system to stop working. When the fuse o r relay fails, it prevents the A/C compressor from turning on, resulting in no cooling. Symptoms of this issue include the A/C not turning on at all, no sound from the compressor clutch, and no airflow from the vents even when the fan is running. To resolve this, check the fuse box under the hood for a blown fuse, and replace it if necessary. If the problem is with the relay, it should also be replaced to restore normal A/C functionality.
