I just purchased my first car, a 90' Nissan 240SX. I'm not completely stupid when it comes to cars, but not far from it. I think my car is burning oil because when i Rev it up a white smoke comes out the exhaust. What tests should I do to find out whats wrong? Also for some reason my blower fan doesn't work. The fan motor is alright, we tested it when 12v from the battery. But when we tested the plugs that go to it from the control panel thing, theres no charge??? I need help. Thanks.
