[micksplace]

i am having drama with the fan blower as it just stopped working
the ac compressor is still engaging as when you drive cold air comes out of the vents have checked fuses all good have power at the blower motor
&when you earth the motor the fan comes on .
was wondering if there is a relay that controls this or is it more complex??
thanks for any help
