SOS.

My 2002 Kia Carnival is suffering from a weird problem. When I turn the aircon on, the brake and battery warning lights come on and the power steering and brakes cease to function.

Actually, if I keep the steering wheel in a turn for more than a few seconds, the warning indicators also light up, and they go off when the steering wheel is centered again. However, the problem is most noticeable when the aircon is switched on.

The mechanics I consulted diagnosed it to be an alternator problem, but I already had my alternator inspected yesterday. They replaced an IC and re-installed the alternator, but the problem still persisted.

Maybe you guys could shed some light on this predicament I am in. Mahirap magmaneho na walang preno
