I appreciate that having power windows at the front might be seen as a luxury in a Defender by some.
Still, LR implementation of it is very basic, as one have to continuously push the window switch to roll down either the driver or passenger windows in full. Plus the switch for the passenger window being on the other side of the dash, I find it rather unconformable to have to bend during long seconds to operate it when I'm alone and driving (and need my two hands to steer and change gears already). In short, my 110 Puma is lacking the one touch up & down feature ! And I decided to remedy this. So here's the write up of what I did if anyone is interested to follow a similar route. A quick search on this forum revealed this has already been discussed and was possible to implement: https://www.defender2.net/forum/topic48715.html I also came across this blog http://defender90xs.blogspot.com/2014/03/o...ndows.html with in depth details, however this is just overcomplicating things, and I'm willing to keep things as simple as possible. I sourced 2x WC1000 units from Autoloc (via ebay) - one window requires one WC1000 unit.  Click image to enlarge The WC1000 unit will be installed "physically" behind the center dash (close to the window switch) with some strong double sided tape and "electrically" between the window switch and the window motor, so that when the switch is pushed "one touch", the WC1000 unit will control the motor to fully roll down or up the window. Another push of the switch will stop the window from moving further if needed to open only halfway for example. The connector (C0321 and C0242) at the back of each window switch has 6 terminals connected as such from factory : Pos 1 : Ground Pos 2 : +12V Pos 3 : to motor : +12V at rest : Grounded when "down" is pressed on the switch Pos 4 : to motor : +12V at rest : Grounded when "Up" is pressed on the switch Pos 5 : unused Pos 6 : for switch light bulb
To move the window up or down, one side or the other of the motor is pulled to ground by the switch to allow current to flow. This is what is called a "negative trigger", hence I have used the "negative trigger" inputs on WC1000. Both Ground and +12V are available at the switch connector already, hence no need to route new cables, I have spliced these to feed the WC1000 unit directly. Another note is that the WC1000 unit is preset to a certain amount of force required to drive the window motors. With my defender this was not sufficient as is, the window was only moving about one mm at a time and stopping. The fix is to cut the the loop wire as printed on the WC1000 unit itself, as this will change the resistors to a higher value in the internal circuit path. Works a treat. Last advice is to test with both ignition on only (engine off) and engine running at idle, to make sure everything works as expected before reassembling. The following picture show the original installation manual that came in the box with the WC1000.

Thanks for a great write up. The lack of one touch does not bother me but it's good to know there is an easy fix.

BW, I would think that what you are describing is indeed possible to achieve although I have not tested it. The WC1000 has 2 terminals for negative triggers which you can use for the first switch and 2 others for positive trigger which you could use for the second switch. Note that that in this case the 2 switches will be wired differently, to either work as negative or positive trigger respectively.

Merlin,
Am aware that this is a slightly older thread. But having recently bought a pair of these from Amazon, I thought I'd mention - they are available periodically. Sadly they are rather more expensive by this route as compared with purchasing directly from overseas suppliers. But having attempted an eBay purchase from a US supplier whose arrangements with the platform precluded payment from the UK and which then took a week and many exchanged messages to cancel, I concluded that sometimes cheaper just doesn't work. They are available from Amazon (UK) right now if you're still interested. Search "Autoloc 9862". You'll need one kit for each window. There is a "two window" kit also "9863", but seldom available in the UK. Warwick 2011 L322 TDV8 A/b Orkney Grey 2008 Defender 90 XS TDCi Java Black 2002 L322 TD6 Vogue Zambezi Silver (gone but not forgotten) And one or two bikes - Ok, maybe more than one or two.... |

I’m waiting to see one day if anyone designs a new physical switch design that is resistive touch or similar solution.
For example one touch down, one touch up. Double tap, half way or programmable height. Three taps stop. Integrated into the existing switch designs, reliablity is utmost importance though as the originals are incredibly reliable. Could be set up with a unit such as this I would imagine. Possibly a 3 point touch design, as the switch would replace the rocker and due to the vertical size that would probably be possible. Off road anything touch could be problematic also though, due to rough terrain being difficult to press accurately. Lots of ideas though ! No Guts, No Glory. 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

See here for some detail on installing a very similar
, but discontinued, product. https://defender90xs.blogspot.com/2014/03/...ndows.html You can do it without cutting the factory wiring. http://defender90xs.blogspot.co.uk/ |
