Will alternator affect AC?
If your alternator is failing, this can cause many electronics in your vehicle to quit working. This includes the engine, the air conditioning, the radio, the windows, etc. Once the alternator has been replaced, the air conditioning is likely to work again.
What should the alternator output be with the a / C off?
The alternator outputs ~14.5 V with the A/C off. With the A/C on, the alternator outputs 10-12 V, the battery symbol lights up, and a ‘Check Alternator’ warning shows up on my display. After some time the steering goes hard as well, indicating loss of power steering.
