I assume that its a relay, but it just happened tonight and didnt look into. So im wondering if you guys have any ideas i can check into tomorrow. So when i turn the a/c off, there is a buzzing under the passenger foot well. When i turn the a/c on it dosnt make any noise. Also, when the relay buzzes my battery light comes on stronger as it would when the a/c is on. So im thinking faulty relay? Is it just above the passanger foot well?

 

Is the blower under the passenger side dash on later cars?

 

Does it happen when you first put the key to acc.? That has something to do with the climate control, it starts up sometimes but stops when I get moving.

 

no it dosnt do it right away. any time I turn the a/c regardless if the car is off or on it will do it.
