wiper motor

hi all well the chassis and electics are all ready for mot bar the wiper motor , it works but very slow and blows fuses even up to 25a ,i have tried one off a series 3 but that parks the wrong way it parks to the right meaning wipers up on drivers side , is there any way to make them travel the other way or is it nessesarry to get a new 90 motor, if so can anyone give me a part number for the correct one
cheers

from memory the gear is swapped round- long time ago but has been covered before.

is that swap the big gear with that of the 80 into the series motor as the motors have the same part no i am tota;;y lost as there are 2 listed for 90 alone and i am unsure of how the chassis numbers work

I only remember it with a 90 as it parked the wrong way, I'm sure that the internal gear was reversed to get it to park the other way-did it on mine, so works on 90/110 wiper motor.

cheers fanatic ,changed the gear over this morning and all is well saved a little dosh there
