This self diagnosis question has come up before, I found 2 you tube videos that run you through this with little instruction videos. If I could find them. using google then so can you. I probably searched something like: auto cooling fan repair (or something like that)

P.S.- I tried to put all the steps into words before; but, my explanation got too wordy ; it is easy to stand beside you and point at what I want you to do but harder in just words with no pictures, The videos were both quite complete.
