Radiator Fan Not Running on 2008 ML 550
Any of you guys have a wiring diagram for the radiator cooling fan circuit and a fuse box layout legend. Info on line is nearly impossible to find. At this point the fan will not run and I have zero tech info to work with.

Open the hood and at the Pre-Fuse Box tell us how many RED wires are coming out of the bottom. Photo will help.

Pur, I am trying to help help but your answer of 3 or 4 does not help me.
Aside from from that huge RED cable, how many other RED wires are there?
Do you own a DVOM (Digital Volt Ohm Meter) or a test light, preferred?

Cooling fan ..thanks
- [QUOTE=Maj. Dundee;8264543]Turn the key to the on position and at the fan connector, test the RED & PINK wires for 12v and then check the BROWN wire for ground.
Ok sorry about the late reply im just working so much ill try but I believe I've done it with the test light and the ground brown when I hook it to a power source the tester does light up and the red also when I grounded it has also lit up ..i just don't remember if I had the key turned
