Db9 2005 drivers window goes up and down on steps

[mike-2txrc]

I have an issue with the DB9 drivers window.

I have tried the window reset but it still goes up and down on steps and doesn't drop when you open the door.

Anyone else had this? I've seen on one post, remove fuse 83 and it resets the door module?

Cheers

It does, but 'steps' sounds like a mechanical issue.

The early window modules get a bit flaky over time and can lose their memory. The fuse trick can restore them but they'll still go wrong again later. Mine have both been reset many times! They can be replaced with later modules if it bothers you too much.

The circuit board on the window regulator has gone , there prone to water ingress which causes the issue. Its either a new window regulator or there is a ebayer who occasionaly lists offering a circuit board repair service for £75.

Cheers all.

I will try the fuse trick first and see what happens but it may end up being a replacement or repair job.

Thank you.

My Vantage did the same. It was water in the circuit board.

Well tried all the fuse things, hard disconnect of the module and also a spare module and it's still the same.

I'm now thinking is it actually a motor issue??

Anyone else had this window up and down in stages issues?

If you're on Facebook this group 'Aston Martin DIY' might be able to help: https://www.facebook.com/groups/amdiy

I am but can't find that group unfortunately.

I'm wondering if it's a motor problem.

Can you buy spare motors without buying the whole regulator unit?

ian448 and 4.7AMV8 already gave you the correct answer.

As above I have bought another module and tried that and it still does the same so water in the module could be an issue but not on two different ones.

If it's the regulator side of things can you buy the motor assy seperate or does it have to come with the whole reg?

Cheers

This happened on my 2006 DB9. New regulator fixed it.

As per my previous , its the circuit board on the window regulator ! nothing to do with the door modules which are seperate from the regulator assembly.
If you look at the window motor theres a black plastic cover held on with a number of screws, remove the cover and low and behold theres a circuit board. Thats your issue

[mike-2txrc]

Ok thank you. Will have a gander at that.after having it apart at weekend it's behaving a bit better but still going in larger steps.

Will have a pull apart at weekend again.

Do you know if they sell the motor units seperate or do they only come with the full reg?

Cheers

not sure about just scourcing another motor, the circuit board can be removed by unsoldering the 2 connections were it attatches to the motor you could then send it to a good electronics shop for testing and repair.

If you do and get it refitted I would drill a small drain hole in the bottom of the plastic cover to drain out any water and prevent further issues

This might give you an idea

Ok thank you.

I'm wondering if it's in water at the moment.

I was hoping it may be a Volvo or fomoco part but hard to tell unless it's stripped

Will have a look cheers
