The cooling fans in my car haven't been running and I have removed the full unit from my car yesterday.

When looking at the unit I'm guessing you buy the separate fans on there own do you? Anyone know how to test these to check to see which is faulty?

If this helps you guide me in the right direction the fault codes I had we're 18353 which was module 1 cooling fan short circuit and 18359 radiator fan 2 movement restricted or jammed.
