So this is a recently developed problem. I think my blower motor bearings are going. AFter a while of running the AC or fan. From inside the dash you will hear clicking. Its similar to if you stuck a pen in a fan and you just hear the fan blades hit the pen, over and over again. Its hit or miss, sometimes after you turn it off and back on its gone. Then it resurfaces later. Sometimes it will go away on its own... Any ideas? Anyone know how to replace the blower motor?
