Is this the Lucas type or the little box type? either way just pop the linkage off the motor and hit the button. If that doesn't work, hot wire it. Frequently, the linkage gets loose and locks the wipers up OR it pops off the wiper motor. Look under the dash and confirm that they are hooked up to the wiper motor first.

Lester,

Its the earlier style and its definitely not the linkage, the motor just stopped working.

Ive removed the motor now, so I can get to it easily. Im not sure quite how to test it, do I just run battery power to the plugin? Remember, Im an idiot. ;-)

Best regards,

You will need one ground wire and one 12V "hot" wire. IIRC those units were mounted on grommets and they have a separate ground wire built into the harness, usually black. And two speed with a park function so two or three more wires.

First, make sure that you are getting good voltage to the unit, turn wipers to on and verify 12v to at least one wire. Turn to high (Don't honestly recall how many settings they have) and verify voltage to another wire *OR* there may be a resister built into the switch so one wire only gets 7V until on high setting then 12v. Not too critical at this point. IF you are getting 12v to those wired then check out the motor. Connect a ground wire to it and then 12v to the hot wire (determined earlier by testing above). If it doesn't go then it may be gunned up brushes/bearings/bushings. If it smokes then more likely bad windings/trashed.
