    Heated front screen not working

    Had a new windscreen fitted a few months ago today for the first time I used the heated screen only to find the drivers side does not work - contacted Autoglass who have agreed to send out a technician - don't really understand the way it works so thought I would ask your opinion should Autoglass try and fob me off - not saying they will as I have always been satisfied with their service.
    I have checked the connection and the wire appears to be connected - I gave a little squirt of wd40 just to check moisture on the connector was not an issue and alas still no luck
    Does anybody know if the screen has 2 separate fuses or could a faulty switch only work half the screen ?
    Appreciate any advice

    Re: Heated front screen not working

    As you say when heated windscreens first came out, they had two lots of fuses and relays (one per side)

    I don't know what the X type has.

    I guess AG will determine whether the heating element has the correct resistance and it is plugged in. Assuming that is ok will then walk away.

    You check for 12v when the screen is turned on, to see if is the car or the screen at fault

    There's two fuses, F14 (LHS) and F15 (RHS), both 30A.

    Re: Heated front screen not working

    Autoglass fitted a new heated windscreen to my old Mondeo and the drivers side didn't work. Lifetime guarantee doesn't apply to windscreen itself just the fitting.

    The replacement windscreen also had much more visible heating elements than the original - gold coloured instead of the orginal's dark elements.

    Hope you have better luck.

    PS I have read that the X Type and Mondeo share the same front window shape, but can't confirm.

    That's great
    Thanks for the advice at least if the windscreen is ok I know which fuse to look at
    I think I can speak for all newbie Jag owners we really do appreciate the time & effort of the replies we get to what might appear numpty questions.
    One day somebody will ask a technical question I might be able to answer, feel somewhat guilty as it seems a bit of a one way street sometimes.

    Thanks again

    Hi!
    I had similar problem in our X-Type in last winter, but just front passenger side did not work.

    Luckily fault was corroded connectors.

    To get to the connectors, first remove wiping blades and arms. Notice, they can be very tight, and almost certainly you need small extractor to remove wiper blade arms. After that you need to remove that black plastic trim. That plastic trim is so called "washing bucket" plastic, so be careful when to remove it that you don't break it. Also, when removing that plastic trim, watch out small wires going to both sides of windshield: those are windshield heater wires and in those wires is some kind of black "things" which converts normal wire to very thin copper ducts. Those copper ducts are so thin that probably they do not need much violence to break. Follow those wires which starts from those black things, and you'll find connectors, both side has own connector. Open that connector, check for corrode. Start your car, put windshield heating on, and check for example with multimeter the "cars side" from those connectors that car gives power to that point. It slowly rises from 0 to +12V and a bit more, so don't hurry After that, check "windshield" side those connectors if they are corroded. Measure Ohms to "windshield" side, I don't remember how much it should be, about 1 Ohm or so. Clean connectors and spray them with for example WD-40, connect connectors and test if windshield starts to heat up. If you can't get Ohm readings, re-check for nasty corrode, or try to measure it from those very thin copper ducts. If you can't get any Ohm reading, the heating element in windshield most likely is totally broken.

    Oh, forgot to mention: If and when you do that, I suggest you renew the pollen air filter at the same, because after removing that plastic trim, it is very easy to change.

    Good news
    Auto glass came this morning and changed the windscreen free of charge - everything now working ok
    Didn't have time to get a pollen filter shame cause as you said would have been an easy job
    Another time perhaps

    Flipping heck the passenger side is playing up now
    4 windscreens in 18 months

    Edited this post as it does appear to work just a couple of mins after the drivers side, might just put up with it, don't think I could put up with having it changed again
