Heated screen woes...

TaDa · Dec 18, 2012

Recently the left hand side of my heated screen stopped working. It had been replaced in June so we thought we'd get the company back to do a warranty repair.

The man is telling me that the problem is "the car".

I've seen the connector and its all black and deformed on the windscreen side and burned and bent on the car side.

It strikes me that this is not a problem with "the car" but a dirty or dodgy contact to the windscreen circuit.
Because the wiring has lasted this many years and works fine on the drivers side I reckon they either did not clean the contacts when they replaced the screen (which I doubt is part of the process anyway) or the replacement screen's connector was just plain broke.

Ok, so I've vented my spleen, the problem is probably just the connector.
Before I wire in a new screen I will clean the contacts but is there anything else I need to check?

Cheers (and thanks for listening)

Although he may read and reply to your post PM PaulMc he can supply of all manor of new LR electrical plugs and sockets plus their pins. Paul may have a replacement connector, much better than trying to referb a grotty old one.

A new plug makes a lot of sense - I'll drop him a line - Cheers!

don't want to hijack this, but how easy is it to convert a non heated to heated? my screen needs replacing, so if it is easy would do it

Depends on what disco, but the basics are fit a heated screen then supply a fused 12v supply to it via a switch and timed relay so easy, it's even easier if the wiring loom is in place already.

In that case unless it's the basic model the wiring should be there, look for sockets below the windscreen by the bonnet hinges so it's just a relay and switch and then tell your BCM that a heated screen is fitted with Testbook or whatever... job done

You'll need to source a heated screen from somewhere too - I'm not too sure the windscreen repair people will just swap an unheated one for a heated one and I doubt new ones are cheap.

Go for it if you can, though, they're very effective.

Of course they will why not? is there a law against that now

. Pay them the £800 + and the jobs done.

you got glass breakage on your insurance?

TaDa · Dec 19, 2012

£800? Wow! Thats almost as much as my car is worth

discool · Dec 19, 2012

I'll have to check out the part number again, the last time I looked it was a few years ago and a genuine part fron LR something like £1100+ for a heated and tinted screen

discostew38 · Dec 19, 2012

Only half my heated front screen works but as it has power and earth to both sides I guess it's the screen that's no good I was quoted aprox £300 not got round to doing yet I was going to wait till the MOT is due and get it do through the insurance "say its cracked)

Come on you D2 owners, know your disco, even I know the relay fits in position 8 in the engine bay fuse box so that's outside row next to relay 3 your headlamp power wash relay.

i haven't even looked, or even opened the bonnet

i thought just ask and see what reply i get

the art of being lazy and doing my paper work,

bills out, money in, pay for disco mods, lol:car:

had screen fitted today cannot seem to get to work, all power there, relay and switch, went on with hawkeye, switch to light up etc, but after that no can do
any advise would be helpful

TaDa · Dec 31, 2012

I wired my screen up yesterday.
First I cleaned the contacts so I could see metal and not burned on dirt.
I added a little wd40 for lack of electrical contact cleaner
Then, with ignition and heated screen on, I checked the voltage at the contacts and got around 14v - (0v when the screen was off (!!))

If you've still got 14v at the contacts since there's no rocket science going on here I can only presume the contacts are dirty or the screen is faulty.

If you no longer have 14v at the contacts - you should check the fuses in the fuse box behind the battery - (IIRC position 7 for LHS and 8 for RHS - the two 40A fuses side by side just over halfway up the set of fuses away from the battery) - if the fuses have now blown the likely reasons are you accidentally shorted the connections during cleaning or testing the connection voltage - or the screen is faulty.

For your sake, I'm hoping its just dirt in the contacts followed by a careless short as you stopped testing the voltage. Hopefully its not the screen.

If the screen does seem at fault, you could take an ohm meter to the screen contacts on each side - it should be virtually zero ohms across the contacts as the heater elements are nothing much more than wire. If you get a significant resistance, then the screen wiring is open circuit and you get the opportunity of demanding a replacement

Good luck!

was yours an orginal heated screen? this is a replacment from non heated, relay and switch from landrover, all shows on hawkeye as live, must admit i only had 20mins or so after window man went, so not really looked into it yet, or know much about this hawkeye thing yet, 2mrow will play a bit longer if not too hung over

1. cleaned all contacts, lubed/waterproffed.
2. checked all fuses/relay.
3. had play with hawkeye, read programes, today selected changes.
