I have a 99 honda accord v6. Today while driving the battery light, brake light, car door lights and the light that indicates the brake light on the back seat all went on at the same time. I couldnt notice any difference in driving. But I have noticed a high 'whistling" sound coming from the engine compartment. The lights all went off when I pulled the hand brake handle. That was a coincidence because I didnt know what to do. I still hear that whistling sound. Can someone tell me what the problem might be? Thanks in advance.
