Wiper problem

[RobR]

Hi,
I have a problem with my window wipers. They don't move smoothly across the window screen but run stiffly. They do so at all the three wiper speeds.
The motor is ok and the blades are new. There is no tolerance in the wiper arms and blades.
I have also polished the screen and used rain-x. The surface of the screen is now smooth but the wipers still operate "roughly".
Does anybody know how to solve this?

Thanx,
Rob

Try chcking the bushes that the spindles run through to come up through the scuttle panel. You'll have to remove the wiper arms to gain access to the large nut on each side, unplug the motor and remove the whole linkage. They have a tendancy to seize up if the car's been stood for a long time. Also check the motor spindle the housing is ally but the spindle is steel not a good combination for corrosion. Once you've stripped it squirt easing oil into the bushes and the motor spindle and then connect it to a battery so tha the oil gets worked in, give it a fress squirt every few minutes.
