2007 Defender 110 Puma 2.4 DCPU Stornoway Grey

An update in case anyone is interested. The problem as I suspected is the advanced wear on the high speed brush. As can be seen in the photo below, the HS brush (the one in the two-o'clock position) is worn almost to nothing. It is half the width of the other two to begin with and the amount of wear means that it is no longer reliably contacting the motor commutator.

Now to see if I can find a replacement brush set since there is nothing else wrong with the motor. Unsurprisingly LR says bin the motor and fit a new one, which is really quite unacceptable now that we are no longer supposed to be raping the planet of natural resources.

For info if anyone has a similar malfunction, a replacement brush plate assembly is part number DLZ000010 and costs around £35-£40*.

* Which is an absurd price but cheaper than around half the price of a new wiper motor of reputable origins.

If measured I wonder if you can get similar carbon brushes, or just the carbon ends and change them out, are carbon ends held in by more than just the copper tabs clamping them blackwolf?

2012 Defender 90 Puma 2.2 CSW Santorini Black

I wonder if you can take the brushes from an earlier unit, RTC198 that comes at about 50% of the price of a later brush unit. If it is worth your time and the risk, I do not know. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

I shall investigate the feasibility of replacing just the brushes, since this would be a much more satisfactory approach.
