Alright here's a quick little write-up just in case someone new to The forum and counters the same issue
1.If the fan is damaged replace it, it's not that difficult you don't need a mechanic it's literally two clips that are holding it in place. I personally removed the radiator hose to give me a little bit more clearance however I can see wiggling the fan in and out without removing the hose.
2. Test the fan by wiring it directly to the battery, to ensure its in proper working order
3. Check the 50 amp fuse it's in this little black box next to the battery it just pops open there's a little diagram on there telling which fuse is for the fan
4. Check the relay (the black square, next to the yellow square lol in fuse box)
5. Lastly if it's a fan control module if you can test one by plugging it in from another Crossfire or SLK.

Luckily my problem was just a broken fan (literally the fan spun itself loose from the housing) and the 50 amp fuse I hope this helps
