Scanner that can activate the radiator fan
Is there Scanner tool that will work on a 2003 ML 55 that will allow me to turn the radiator fan on and off? Or is there another manual way to get it to activate?
A few years back, it used to sound like a jet plane it was running so hard, it does not kick on any more. I am not sure if its the computer (is it sending a signal?) or if its the fan itself broken. Is there a way to test?
It does spin, but never seems to spin up faster when the engine temp is hot.
I have a LAUNCH CRP 123E and I am not sure if it can do this or not. If it does, I could not figure out how to get it to work.
Thanks for your thoughts.
