COOLING SYSTEM

2003 Cadillac Seville

Heater problem
2003 Cadillac Seville V8 Front Wheel Drive Automatic 50,000 miles

why does my seville start to make a ticking noise only when I turn on the fan on the drivers side. When the heating and cooling system is turned off there is no noise. When the fan gets turned on the ticking starts what could this be?

Does the ticking vary with fan speed commands? It sounds like something in the fan cage, like a leaf, parking stub, or similar.
