Belt Sqeals randomly only when the heat blower motor is on
I have a 2004 Hyundai Accent with a random belt squeal. I have replaced all 3 belts and still get the random squeal. It is intermittent and I happen to notice it only occurs when the heater blower is on. If I cut it off, the squeal doesn't occur. When it does happen, it doesn't matter if you let it idle or accelerate. It is impossible to predict when it will happen making it very difficult to find the actual problem. Any help would be greatly appreciated.
