Windscreen Wipers

in intermittent mode the wiper sending unit sends like a pulse of electricty to make them work and then they return to the rest position, maybe the returning to the rest osition isnt working. sad thing is I dont know which bits resposible for the rest bit, the motor or the switch. I'd try the switch first

Sounds like the old age problem is on you. Bite the bullet you are going to have to replace the switch unit which of course will cost a heap. Its just probably a $2 bit that has gone futt but the whole unit will have to be replaced.

I had a Ford Laser that had a problem that it was not cancelling the indicators out on the return of the steering wheel. The plastic piece inside the switch had worn out. Down to Ford to get one of the pieces of plastic - no go. Could only buy the whole unit for $160.

A couple of weeks later the same thing happened to my 1963 MGB. Off to the local MGB spares shop to see if I could replace the piece of plastic or if I had to buy a complete unit. Hey presto the plastic bit was available in a kit with the special rivet to replace it for $5. I told my MGB guy about the Laser and he told me it is a matter of safety that on new vehicles you have to buy the whole switch built at the factory. You were not allowed to play with them.

Hey ho off you go with the placcy.

Like my Frontera but wish they did them in diesel.

brian.. my wiper started doing a similar movement to that a couple of months ago...
is had simply come loose off the rotator.
clip off (carfully) the cap on the bottom of the wiper... and do up the nut which holds the wiper on... see if that works?..
if not.. you know the answer.. get out the cheque book!

I would suggest the problem lies in the wiper motor.
The wiper motor has an auto-cutout internally to ensure it completes it's cycle before stopping when it is disconnected from the power.
The internal cutout has a dirty connection.
If you use it on slow speed and disconnect at the right moment ie after it's normal rest position but before it stops on the intermittent position, it will stop as it does on intermittent.
Not easy to explain but is a common occurence with wiper motors.

Not having worked on the model vehicle you have, I cannot say.
How hard is it to pull the motor assy out of vehicle and is it a sealed unit?

I find windscreen wipers are connected to the wiring loom via a plug connector which is easily accessible.

May I suggest you take a wander to a local wreckers who has a replacement and substitute it into the loom in place of yours and test it on the spot.

If the unit operates ok then you know your motor is the problem.

Another test: remove the wiper blades, remembering their position, and then try the intermittent wiper function. Without the blades there is less load on the motor and it may "jump" the faulty part of the track and complete its cycle. This would also indicate the problem is in the motor.
