08 SS overheats, fan not running, fan is good (jumped it) according to wiring diagram should have fuse and relay, but not in the fuse box. I've owned it since 30k didn't start this problem until 60k. Does have a control module of some sort connected to the fan. Any ideas?

 

There is a control module. I seem to remember reading in one of the other "SS overheating" threads that the book is incorrect.

Try the search box at the top of the page, it works.

 

Give this thread a read, SS's have a cooling fan control module....
