Windscreen wiper motor repair and brushes replacement

It all started when the windscreen wipers started to seize. I thought the problem was with the mechanism itself, disassembled and oiled it, but it still kept seizing. Finally I got problems with the fuse and the wipers stopped working.

First of all take off the motor, remove the plastic cover and unscrew two screw-bolts, and carefully remove the magnet.

After the screw-bolts are unscrewed, check the brushes condition and if it’s poor – go ahead and remove them as well.

Here’s what they look like:

You’ll need to purchase new brushes similar to yours. Those from an electric drill will also do.

Turn the brushes till they are of the same size and shape as the old ones.

Place the brushes back and solder the wires.

Then assemble the whole device and enjoy your windscreen being as good as new.
