Windows

[jon haines]

Has anyone thought of or done a mod that allows the windows to drop when you open the doors and the raise again once you shut the doors? I know the Cerbera uses it. I just get anoyed at the fact doors dont shut easily or the glass catches the top of the targa.

Hi Jon


I did think about it last year but only would of needed it on the passenger side...I rarely have a passenger so didn't bother...

I have no doubt it could be done maybe contact Paul Smith he should know

You would be able to do this by building a small processor to tell the window to wind down when the door was opened and close again when the door was shut. Probably triggered by a signal from the courtesy light switch. On the first signal a relay powers the motor one way (down) and on the second signal the relay powers the lifter the other way. You'd need something the the processor which recognises if the window is already down when the door is opened so that it doesn't wind the window up and then send it down once the door is closed. Shouldn't be too difficult for the average 12 year old

Do you mean drop before opening the door?

I reckon you could probably manage this with a few switches attached to the lifter mechanism, along with the courtesy light switch, and you may not even need any fancy processor, just a relay (similar to the pods) . Oh, bugger, did I just actually use the pods as an example ?

Surely a door handle operated switch would be the way to go about this for the opening circuit
Am I correct in thinking that the Window needs to drop before opening the door?
A door switch can be used for the closing circuit

I think thats how it works on the later cars...This might of been what put me off..interestingly I have a central locking solenoid on my door mech...I have seen this on other Wedges but have not seen anyone with an original fob...Me included!...

Ok, the same method can be used on a wedge

[mrzigazaga]

I seem to recall that when I was considering it there was limited space to access the door lock/handle area without cutting some fibreglass out....

I was thinking about this very idea only the other day. The windows need adjusting on mine as they now raise a little too far. It's better whilst driving but the window does catch the roof when the doors are opened and closed. So this idea would be good.
Correct me if I'm wrong here but I don't think there is any limit switch on the window/motor. It just relies on the cable and stop at the top of the runner to stop the window traveling too far. So you would need something that knows the window is at the top and stop the drive to the motor. If it tried to drive for too long after the window was at it's stop I suspect you could burn something out.

I have this window drop feature on my BMW 645 ci drophead as standard and I have to say it is useful and works well in clearing the canvas hood. Having one built into a Wedge though is another matter. The window mechanism on the wedge is not the best design in the world and is unreliable in its present form. Adding a glass drop mechanism in my opinion would make it even more unreliable and prone to constant problems. I find that if your windows are well adjusted and the hard roof fitted on more carefully and centrally usually clears the windows both sides.

Central locking on early cars were only operated with the drivers door mechanism and I believe this was the case with the Wedge. However, some owners integrated it into the alarm system to lock and unlock with the alarm system, some even going as far as fitting total closure. I have only had one wedge with a working central lock and that was operated by the alarm fob too. As far as I’m aware the Wedge never had a fob operated central lock from new.

Position sensors/switches can be used for up and down positions or a current sensor for up and a position sensor/switch for down.
The most difficult part of the job will be sourcing/building a decent 1 to 2 second timer to operate the up/down output relays, there is a possibility that a timer wont be needed but I'm not banking on it

[v8s4me]

There's lots of little processors on eBay like THIS. I don't know if this particular one would do the job but it would be surprising if something suitable wasn't available from China for a few quid.

Needs to be wired to battery +ive, there would need to be a aux or ignition +ive used to switch the standard windows circuit back in

Is anyone really interested? Is it worth achieving?

Would it be simpler to just drop the window when the door is opened and then close it again from the switch? That way you'd only need a simple power feed from the courtesy light through a 1 or 2 second timer. That would take the window a couple of inches or so.

[jon haines]

Bugger this sounds like a job too difficult for someone who has to think when wiring a plug! The only way to limit the lift without relying on the stupid cable set up is to bend one of the teeth on the window mechanism, as it already has that but it was designed for the rover which had greater travel. the other reason i thought it would be a good idea is that it would eliminate the pressure that exists when you come to shut the door again without the need for a vent in the passenger side door trim which again is s***e. A bit of though required on this one.

Hello Jon

I have sorted this, would you like me to send you a diagram or post it here
I need a little time to draw a decent diagram as I only have a scribbled version at present

[v8s4me]

I think THIS is what you need. It will send a current to the motor for 1 or 2 seconds which will drop the the window a few inches (powered from the courtesy light switch). You can then lift the window back up using the normal switch once the door is closed.

Watch THIS to see how it works.

You'll need to put it in a waterproof box inside the door shell.

Easy peesy
