Need Help with my Blower fan Motor Kubota M9000

[Brianmire]

Hi Everyone, I'm new to this forum. I have an issue with my Kubota Me9000DTC. I recently purhcased it and when I got it the aircon wasn't working.

The cab blower fan motor was working but all of a sudden the fan has stopped working. I am in the process of repairing the Aircon (Fingers crossed I can get it working)

I have power to the relays and I have power to the fan switch inside the cab but there is no power on the 2 pin connector that is connected to the blower fan motor.



Some things I have check

1. Replaced the Fan Switch.
2. When i oush for a/c the switch lights up and compressor clutch engages
3. I checked the resistor and there seems to be the correct ohms in each pin. All three pins have different ohms and I assume this is related to the speed of the fan.
4. I tried swapping out the relays and the a/c clutch engaged with all three relays when i tried them, but still no power to the connector leading to the fan motor.
5 The rest of the cab has power.

Is there another fuse I am missing?

I am hoping there is someone out there that can steer me in the right direction.

Thanks in advance

You might also check the continuity of the wires to the blower motor from the switch. (Be sure there is no power on the wires when you check continuity.)

Or a better check might be using a test light on the blower end to see if there is power to the blower when you operate the switch.

Is the blower itself operating if you connect power to it?

Hi Russell, Sorry for the delay getting back to you. I was hectic at work this week and only getting a chance to work on the tractor today. I will try that and let you know. Thanks so much for taking the time to reply to me. I really appreciate it.

Regards Brian

A little update. There is power to the Fan. I checked the resistor and I think this is the problem. My only issue now is sourcing a resistor in Ireland/Uk
