Gen 1 R53 Mini Replacement Rear Windscreen Wiper Motor

Failure of the Gen 1 New Mini rear windscreen wiper motor is quite a common problem because of the way in which the windscreen washer fluid is supplied through the motor shaft to the wiper arm. Leaking washer fluid will enter the motor and switch module and ultimately destroy the mechanism. Early symptoms are the incorrect parking of the rear wiper arm on the glass when the wiper is either turned off, or else during the intermittent wipe cycle.

The biggest problem associated with replacing the Gen 1 rear wiper motor is that it is no longer manufactured or available from BMW. The motor and wiper arm unit was changed with the release of the Gen 2 'face-lifted' Mini (in 2006?) and the complete motor, arm and washer assembly is different to the original one.

If you order a replacement motor from any source, you will be supplied with the new design which has different fixing locations, requires a different wiper arm and also has a different format electrical connector for the power supply.

I understand that BMW will supply an upgrade/conversion kit that will allow you to fit the new type motor, a replacement wiper arm (with different washer arrangement), and a wiring loom adaptor. If purchased with a motor this costs something like £160.

Alternatively, you can easily obtain a 2nd hand original motor from a breakers yard for about £25-30 provided it has been removed from a 2000-2005 car. This is easy to fit, once you have removed the rear hatch lining. This is pretty easy.......it's held in place by a couple of screws and a series of the usual body/trim pegs around the perimeter. The old motor removal requires the release of the external nut on the motor/washer shaft, and the bolts inside the hatch holding the motor to the door. Replacement is the reversal of the process.
