I have a 2003 Chevy trailblazer the engine fan is noisy it rattles and wobbles. It seems like the fan will fly off at any tme. The noise is there when driven and at idle. The sound does not go away when air condition is turned on.

It's very clear what the fan clutch is attached to has a bad bearing. Next you'll get a coolant leak or the fan WILL wobble enough to damage the radiator and that adds to the expense of the repair. You should change the water pump. Soon.
