My broken windscreen has been replaced by a windscreen with a heating element installed. I find two conections in each A-pillar.
How can i get this screen heater working the most easy way and is a timer needed for the relais?

 

Not a common option in the US. You will get a better answer from the UK Jaguar forum.

Lou, please provide vehicle details. It might be as simple as finding the HVAC unit that has the heated windshield button. (I am referring to the 00 - 02 S Types)

Thanks...

 

My Jag is an S-type 2005, 3.0 A/T, VIN N27895. It has a DEF function switch, but lacks the screen heater switch.
I do have a my 2003 wiring diagram, but not the 2005 version.
Do you know if is a single or a two-zone heater? I expect a two-zone system will have three connections, but I can only find two of these.

 

You know most have heated wiper park(wire grid where wipers park so they dont freeze to glass) and not heated windscreen. The windscreen has very small lines wires and theyre also very expensive. You sure you have a heated screen?

 

The OP is in the Netherlands so his closest source of supply is the UK. If the heated windshield is popular in the UK then the odds increase that it is the default item available in the aftermarket supply chain.

The only requirement to run a heated windshield is sufficient power. All of the other features like tying it in to the defroster system and auto off are just nice to have. Important to have because waking up to a drained battery is no fun, but a careful owner could run one with a manually controlled relay with the control poles tied into ignition controlled power successfully.

 

The heated windscreen in the Uk came as part of the winter pack, the wiring will be there but you will need to fit in the fuse box (and connect wires to them) , as they would not be fitted to the box F25 Right hand side and F30 left hand side, have 2 relays R17 left hand side heater and R21 right hand side heater these are switched/controlled via the air conditioning control module and a switch.

You should check the UK forum to see if anyone has retro fitted one?

 

Thanks for all this, but...

I already checked all existing fora, but can't find any answer to my questions. And yes, it is a heated screen, not a heated wipe-park only.

To repeat, my questions are:
1) Is it a dual zone system, and if so shouldn't it than have a minimum of 3 connectors. I can only find two.
2) Is a 2005 S-Type wiring diagram available? If so, the first answer is given as well.

 

The OE heated windscreen setup in the S-Type is likely to be much the same as the one fitted in my XK8.

The wiring schematic certainly looks similar on the two models and, for this option, unchanged over a number of years:



The LH and RH heater elements are each single zone and operate together, not independently.

The owner handbook clearly shows it is dual zone.

The 2005 and newer wiring diagrams are on jag's TOPIx so just join & download if you want them.

 

Dual Zone - four separate heater elements. I bet that's a horrendous price!

I had a development one of those fitted in my XJ6 Series II in the 70's when Triplex were (trying) to develop them and gave up at that time on grounds of manufacturing cost.

Graham

 

They're not too bad. My STR has one, as did my previous (Ford) car

Probably more-or-less standard over here. We have such great weather...

 

my little ford fiesta used to have a heated screen (quickclear is what ford call it i thnk)

that and the fuel economy are the only things i miss about it.

 

I cannot get acces to TOPIx, since I am a private owner. Or is there another way around it?
Can yuo let me have a copy of the 2005 wiring diagram?

reg's, Lou

 

You can still join. I do not believe the diagram will have changed in the area concerned but it is up to you.

BTW, jag fitted an up-rated alternator to cars such as mine to handle the extra load (which is large).
