I'll gladly give you a link Nathan should you decide to keep your original 3 speed motor and repair it economically.

Should the fan be repairable I will for sure do that, been looking forward to taking it apart to check out the problem since writing the first post hahaha. I think I found the link in other threads posted, it is the product from engineeringcarbonproducts right?


With the video Arctic linked and the How To on removing the front bumper and all the bits in front of the fan I'm confident it will work. Now hoping that a fan repair and condenser replacement will have my AC running nice and cold before summer really hits

some members have said that after removing the plastic fan blade assembly, they had to replace it. i had no problem with mine. however i did mark it up to be fitted back in the same position , and made sure it ran true. again , a little care might be beneficial whilst removing...

I had the same problem with those screws and ended up having to cut a slot in one and use a big flat-headed screwdriver to get it out. I'd recommend getting some new screws to replace them at the end.


Also, I never did actually remove the fan blade part, the circuit board part is where all the magic happens and that can be fully removed so unless there's another reason I'm not aware of, I don't think you need to go to that trouble.

It's a bayonet fitting. Mine's still going strong in excess of 100,000 miles!

If I remember correctly they have Torx heads which are the worst to release when rusty.

That's understandable Hector as your 1.8 resistor system doubles the life of the motor brushes. KV6 3 speed owners who wish to renew worn brushes will need to remove the fan blades and the motor end cap to do so.

Hi Simon.
I have never ever removed the fan blade unit on any replacement of the brushes, or repairing the motor, there is no need unless you purchase a new motor without the fan blade.

Your pictures are better than my memory Steve! I did remove mine though, in order to put the motor in the vice to bend the end cap tabs. You must have a clever method for that too!

Due to bad weather and delays in the shipping of the parts, I did not get around to replacing anything on the car before going to the mechanic today. After discussing with him, we decided that the best approach was just filling the car to see if it holds coolant. This all went fine and the car held all its coolant.


Here is the interesting thing: after filling up the aircon, the condensor fan was running again when doing the demister test!

Based on this, I concluded that the demist test for the front condenser fan only works if there is sufficient aircon coolant in the system!***

***For future reference, this does not seem to hold true for every car.



I was under the impression that turning the aircon off and demisting on should not require any aircon functioning, making the results a bit suprising to me, however this might be a nice sidenote to keep in mind when conducting the condenser fan test.
