Problem: The passenger side window doesn't drop down when I open the door either from inside/outside. Sometimes it moves down less than 1mm but sometimes. The driver side window works fine.

What I tried: window reset and battery hard reset

What happened: I got a battery drained a month ago and had to jump start and window reset and hard reset. The windows have worked fine since then. (Now a charger is connected to the battery)

I can still roll down the passenger side window but it doesn't really move down/up when I open/close the door.

I have tried to find a solution from this forum and I might have to do something on a regulator or door module or strike plate?

Please let me know what I should try first in this situation.

I apologize if exactly same problem/solution had been covered in other threads but I really want to get THE solution before I do any action.

Looking forward to hearing from you guys. Thank you very much in advance.

 

I had a similar problem, but only in cold weather. Dealer reflashed my door module and it's been fine ever since.

 

Have you done it in the right succesion, the window reset after the battery reset?
Window reset:
fully up, hold for ~15 seconds (mine makes 2 noises first a "clack" and a few second later a "click", I need to wait for the click...)
fully down, hold for ~15 seconds ( wait for the click...)

 

If there is excessive play in the window meaning you can grasp it by hand and move it up/down then it could be slop in the regulator. Which would need replacement. Door module replacement requires both modules and new software.

 

Yes, window rest after the battery hard reset.
I held it for about 4~5seconds until I hear clack/click but I might have to try to hold it like 15seconds as you said.
Let me try tonight. Thanks~!!

 

Thanks for your answer. How much did they charge for 'reflash the door module'?

 

There was no excessive play in the window. Pretty tight so I couldn't move it up/down by hand. Thanks for your answer though.

 

It was part of an annual service, so no separate price. Should be less than an hour.

 

You can't "flash" the existing door module, software is only available for updated door module pair according to the parts description.

 

Note that the window is held in place ( inside the door) with two screws that actually go through the window glass. If these are not tight the window will exhibit excessive play that has nothing to do with the regulator.

 

And I think you need to be inside with the door closed..

 

hi. Late on this topic. Just an update that be of help to anyone. I had the two modules and software installed for about eight months now. All working fine. Then out of the blue passenger window dropped all the way when the door is opened.functional from the inside with door closed. Will only go up when window manually opened all the way down. Then for the whole weekend behave itself. And so it goes. The soft reset option is no longer there with the new modules. The audible sound/click isn’t there. I’ll ask my local tech if it can be flashed. Will update all.

 

...and fingers crossed and holding the hand of a certified aston service technician .

 

And the fact, it's the Technician crossing their fingers.
