Hello, my name is Bobby. Which fuse or relay are you looking for?

Expert:  Lou P. master tech replied 1 year ago.
Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. The fuse is a 100 amp fuse located inside the PREFUSE box which is part of the jump start terminal in the engine bay. You will have to remove the box and replace it I am not 100% sure those fuses inside are replaceable most times they are not.
But inside there you will find the fuse. There is no relay because the fan module is its own internally controlled module. So if you have no power on the big red wire then the fuse has popped. If you have power then the new fan may be faulty if it's not from Mercedes. I have seen new fans fail right out of the box. Let me know. Hope this information helps Please take a second and click the box and rate my service GOOD OR EXCELLENT SERVICE if you feel I have been helpful and please request me in the future. If you feel I have not been helpful please DO NOT RATE BAD OR POOR AND WASTE YOUR MONEY , I will opt out to see if another expert can provide more or better assistance so you're not wasting your money!!.
