Good enough for me. Thanks guys.

 

I wonder if this is why Jaguar didn't allow the rear windows to be up when the roof is down in the first place?

Another thing that bugs me about the roof, is the fact that you can raise and lower it with the key in the door, but not by using the remote fob. Has anyone done a fix for this?

 

Hmmmm, good thought!. I've got to add that to my 'todo' list.

 

I had a 2000 X-Type that would roll the windows up or down if you held the lock or unlock button on the key fob.

 

Yeah, I've thought about maybe using the lights on or the boot open button on the keyfob to operate the roof switch - one press for boot, two for roof? Problems include the roof switch not working when the ignition is off and having to make sure you couldn't accidentally open the roof.

Let me know when you have got it working.

 

WhiteXKR, if you watch those two XK8 handover videos that K.Westra posted a week or so ago you'll see that the fob buttons do various things depending on how long you hold the button or how many times you press it. I forget exactly what the various button presses do, and I'm not going to wade through the entire video trying to find that info, but I bet a creative person like you could come up with a way to open and close the top with the fob. Heck, I never use my trunk or alarm buttons. I bet it would be possible to program those to open and close the top.

Sometimes I wish I was MacGyver. He could probably reprogram the BCM to make the convertible top do what we want just by pressing some buttons on the radio.

 

Actually it would be pretty cool to hack into the BCM and make the car's behavior fully programmable without adding relays and time delays.

Ahhh, but spring is here...time to upgrade my intercooler first

 

In my write-up on controlling the back windows, on the first page I added a note about how T-Taps can be unreilable and recommemded soldering or crimping as a better alternative.

Well, I have found a better, easy to use tap connector that is more reliable: it is called a Posi-Tap connector. Soldering is still best, but this is worth considering as a time saver:

Amazon.com: Posi-tap Connectors, 20-22 Gauge Wire, Bulk Pack of 20: Automotive

 

Just thought of this when driving today...will this new version all controlled by the top switch work raising the windows when the car in in motion above the 10 mph mark? Just curious

 

'Up' will work. 'Down' uses the logic already in the vehicle, and I think it will work, but I cannot drive it to verify it at the moment....my car is in a state of dissassembly working on the remote top control !

 

You can roll down the rear windows at any speed.

 

Right, I know "down" always works, was just wondering if the "up" would...thanks

 

Will this switch work?

5PDT Momentary Automotive Window Switch

I'm somewhat electrically inclined but am not sure what the extra poles are for? Is the middle tab ground? And the two outers on each respective side connect whatever wire connected to middle common ground? Meaning I only need to connect three of the wires (ground in the middle, and one of the two other wires on either side) to the switch?

I was also thinking - I only really need the windows to go up with the switch considering we can always press down on the roof button and then back up to raise the top to avoid the convertible hitting the window. What if I found the wire that raised it, and then used one of those pulse relays to pulse for 4 seconds when I pressed the button? Would that work?

Thanks guys - really excited about trying this!

 

That switch will work, but if I had this to do all over again I would just get a push-button momentary switch with normally open contacts (pushing the button closes the contacts). That switch would raise the windows. Lowering the windows can be done with the convertible top button.

 

Well I have just got very excited reading this, I am just glad it was finished! All I have to do is translate the parts into English English and I am away!

Thanks. This is a mod that I have always wanted to do as it cuts out so many complaints from the back seat passengers.

 

You actually put people back there ?

 

This may help with your translation:

Oh yes, its amazing how you can shrink kids by taking all the air out of them and breaking their legs just above the ankle and knee. They dont seem to mind a bit.....

 

Thanks for the translation sheet, you say tomaito and I say tomarto etc etc, but I guess that depends on what part of our respective countries you come from!

But still cant find a pulse timer in England, can buy from ebay USA but last time I bought anything from the US I got absolutely stuffed with import duty, equivalent of $20 on an $8 item.

As for diode what specification does it need to be, again 1N4001 seems to mean nothing here.

Thanks

 

It is just a 50V, 1 Amp silicon rectifier. Most any silicon rectifier will do with equal or greater ratings.

You may also be able to find a relay with integral negative spike protection, in this case the diode is built in. The 'Ford' relays in the Jaguar's fuseboxes are like that. If you use one of those, the coil connection marked '86' must be the side connected to where the cathode of the diode in the diagram goes. '85' is the other side of the coil.
