Windscreen Wiper Speed / Motor

[Tarmac Tickler]

I have not paid too much attention to my windscreen wipers yet as I have avoided using my S1 in the wet so far.
Went for a drive recently and needed to clean the windscreen because of the low sun and even though the the wipers work they are very slow, is this a "they all do it" scenario and any suggestions on what can be done to sort this out, can something be lubricated or does it sound like the motor is dying?

I would have thought it was an MOT failure too?

If it comes to a replacement motor what can I use please?

Thanks....

Thank you both, I will do some further investigating.

I forgot! DONT put your hands under the dash when the wipers are running. It is OK with the cable type but the earlier crank arm type is dangerously accessible on the passengers side in particular.

OK, thank you for pointing that out.

Thanks again everyone, much appreciated.
I have plenty to go on now once I get some time to play.
