Massey 6480 cab fan blower

[MasseyMad7618]

Hi all 2011 Massey 6480 the cab blower has stopped blowing air on all 4 positions. Resistor was fitted a few months ago and been fine since but just stopped again the other day. If you give the roof a thump you get a whirring noise then nothing again. Any checks to confirm it’s the motor gone?
Cheers

12v direct to the motor

Mine has done the same thing , it is the switch in the cab that has failed on ours.
To get at the switch pry out the row of switchs in the cab and take off the 5 pin jack connector then use jumper wire between pins to check motor speeds , if motor work s on all 4 speeds then your switch is broken .
if no motor works then the problem is the motor or under the roof top hatch

Thanks guys. Have got the roof cover off and had a look inside. Had the switches set on two and air con on and got a little motion from blower which increased in speed when I applied pressure on the circled red part. Does this sound like the blower is goosed?

the fan on speed number 4 should be direct 12v drive
the resistor slows it down subsequent numbers

Mine blows when you turn it on but the speed doesn't increase when you turn the switch. After a while the blowing virtually stops.
Any ideas?
