Battery replacement- now passenger window won't work

Recommended Posts

Hi Folks,

Had to replace dead battery. Went fine but now the passenger window is stuck in the down position....and it's pretty cold.

Any suggestions to get this window working again?

Worked fine before the battery issue.

Thanks

Gino

You need to re-train the windows. You do so by pressing and holding the button down - all the way down and an additional 10 seconds. Then do the same for raising the window.

It's been covered here many times before so give our search a try next time.

Hi

I have exactly the same problem on a 2000 996 Turbo, the window went down on its own accord during the battery change. I have tried the reset for 10 seconds but still only a quite click sound - no movement. The drivers window is fine. Any more ideas.

Thanks

Try a reboot, remove both cables from the battery (+ and -) and connect them with each other by a jumper cable for several minutes. Reconnect them and do the re-train procedure over again, also keep the radio code on hand.

Hi

I tried the jumper connection but still no up action. It seems it did do something as there is now a double click when you press the window button. I left the two leads connected for about 4 minutes, is this long enough.

Many thanks

Hi Loren

Any other ideas on how to reset the window.

thanks

Did you try the window reset procedure (2nd post in this thread) after re-connecting the battery?

If that does not work they may be something wrong with that window and a microswitch.

Yes I did the 10 second reset.

What was strange is that the window was up as normal but when I changed the battery I did something that made the passenger window go all the way down and stay there, the drivers window is fine. I cannot understand what made it go down in the first place.

Thanks for your thinking time.

The power windows share the same fuse, and circuitry - so there must be a problem with that window microswitches or motor.

Perhaps a coincidence that it happened during the battery change.

Hi

Yes coincidences are always a puzzle. Motor should be OK because it went down nicely. So I must have either confused it and am failing to reset or something wrong with a switch. Seems strange that it was fine before the battery disconnect etc. I am hoping that somebody has a suggestion how to un confuse it. I am not keen to dismantle the door without it being the last resort.

Any ideas gratefully received.

Thanks

Hi Richard

Good idea, i will tyry it tonight. Noted while trying resets over the weekend that the window has gone down further than it should have, lower than the drivers door does, this may be the problem, it has gone past a switch.

Many thanks

Roger

This might be a long shot but, if your Boxster is a convertible, get inside, close the doors and roll both windows down. Put the top down. Wait a couple of seconds, then put the top back up and lock the safety latch. This should make both of your windows roll up automatically. Hopefully that works. Good luck and keep us updated.

Hi RS,

 

Long shot if you will get notified of this reply.

 

Did you solve the issue?

 

I have exactly the same problem with my 986 Boxster with the drivers side window - it will not move up at all (can hear the clicks ok)

 

Happened after re-charging the battery.

 

Would appreciate any further info...

 

Cheers

Did you try the reset as described in post #2 from Loren?

 

Does the passenger window work? Will it lower slightly upon opening the door? This is to diagnose the fuse.

 

If passenger window operates - at all - then while both doors are closed try lowering the convertible top, wait, then raise it, see if one or both windows move to the closed position.

Hi ttocs 

 

the passenger window works perfectly - fully up and down; also lowers on door open and roof lower.

 

i have also also tried lowering the top - no improvement.

 

really frustrating

I also tried disconnecting the battery (twice)

 

although only waited 5 mins.

 

maybe I should wait longer?

 

there is no rough noise from door thus I’m sure it’s not the regulator

Thought i'd record what i found for posterity.

 

The issue was the driver's side (UK) door handle micro switch. I stripped the door down enough to view the window motor spindle. I could see that it was only (intermittently) driving in one direction. Thus i guessed there was a logic issue. I started exercising the door handle microswitches then i noted that I was able to get the motor to drive in both directions. Re-assembled the door and the window is fine now. I guess that the circuit 'thought' that the window was already fully up and would not allow the motor to drive in that direction.

 

Hope this helps someone.
