Non functioning rear wiper

[D813YBB]

The rear window wiper has packed up on my Maestro. It doesn't work on either the wiper switch or rear wash / wipe switch. I have swapped fuses to see if that was the problem but no luck.

Before I invetigate a replacement motor is there anything else I should check first that could cause this problem?

Are the wiper motors used on any other model of car?

Hi,
I would check if you have power to the motor first and if not try a supply to it to see if its OK. Then you know if its trying to find a broken wire somewhere or new wiper motor.
I don't know if the Maestro hatch is the same as the Montego Estate tailgate but I did have a holding bracket slip on my Monty that quickly cut through all the tailgate wiring! but didn't blow any fuses at first!

It may be that the grease in the unit has dried up over the years of use as happend in my monty est rear motor . Just remove the wiper and undo the plate clean out the old grease and repack with fresh.Then test motor before you put it back on the car,just in case it still doesnt work.

Wiper Fault

Have had this on several Maestro,s and found that the spindle can sieze in the housing as one is Allumium and the other is steel. Check the power and if its ok undo the nut attaching the spindle arm to the Motor inside the tailgate and see if the spindle can be moved freely. If not strip and remove corrosion in spindle housing and regrease. There is a small circlip under the outer plastic top cover, that holds the assembly together, beneath the Wiper arm blade assembly.

It was finally warm enough to inspect the wiper motor today. All the wires were correctly connected. On removal of the motor, it is difficult to tell which part of the spindle is supposed to rotate as everything is siezed solid. I attach a photo of the motor showing the spindle.

I removed the back plate and everything was well greased up on the inside.

The motor seems dead though.

Hi there,

I've seen this before where (as someone else said above) the spindle seizes due to corrosion. I went out and bought a new motor and then fixed the old one with WD 40.

This is good news for two reasons:

1. You may be able to free yours up
2. I have a brand new motor that I don't need!

Cheers,
