Hi Forum,

I am new here as well as a new ducato 2000 2.8jtd owner.
Since i bought it the heater fan stops and starts running whenever it wants but 90% of the time it just not run at all.

Since i changed basically every component and there is 12volt on the fan motor i suspect a faulty earth contact.

What i changed/ did

- new Heater motor
- new heater motor resistance
- new heater knob
- check fuse box in glove box, no melted fuses or melted connections underneeth fuses box
- check heater relais, all working and no melted or faulty connections

My question is, since there is 12v at switch position 1/2/3/4 but the heater motor is not running, there must be some resinsance further way in the circuit. Does someone here has some experience with this issue and/or solution for this?

Also a wiring diagram would be nice to find the earth locations and follow the complete circuit but somehow i can not find any diagram since it must be on the elearning thing. A screenshot would be very nice.

Someone help me!

Sorry I have nothing too much to contribute. If the power is going from switch to motor, the next step is to check at the motor that it has arrived there. It sounds like a bad connection at the motor or a motor beginning to give up. I have never had a motor apart. Hopefully someone will be able to tell you how its powered.

I love you handle!!
