    Window regulator #2 broken

    I had opened the RH rear passenger door window when I was cleaning the inside of the car today...as I was closing it I heard the dreaded crunching sound of the regulator eating rusty cable. Predictably, the window stuck immovably half way up Neutral

    I whipped off the door card and plastic access panel, tried to slide the glass up by hand but it was jammed solid. I couldn't even get to the long run of the cable to snip it and free the mechanism up... so, had to pop the glass out of the plastic clips on the regulator frame to allow me to slide it closed. I jammed the glass up with a 15cm piece of soft wood braced against the centre door frame and refitted the access panel and door card.

    The Remote app keeps informing me that the window is open of course so I can't use the climate start until the regulator is replaced and I've recalibrated the windows, but at least the Bling Barge is weather tight without the use of gaffer tape and plastic bags in the meantime.

    Bought an 'OE quality' after market regulator from Ebay for £70 which will hopefully be here by the end of the week...since it's coming direct from Yorkshire instead of China. I seriously hope it's not OE quality, since the expensive Land Rover ones keep breaking. Rolling Eyes

    I won't ever scrimp on fluids, filters, brake/suspension components or anything structural...but we're talking about a window winder here... you press the button and the window goes up and down. An OE replacement regulator from Land Rover (exactly like the 2 that have already failed on the Bling Barge with the same fault) are £200- £255...each...and good luck finding a Land Rover official stockist that has any on the shelf. Wink

    At those Ebay prices and coming from a recognised UK parts supplier, I'm tempted to buy spare regulators for the drivers door and LH rear passenger door... the ones I haven't already had to replace, to stick on the spares shelf in the garage ...just in case. With 2 window regulators having already failed in the year I've owned the Bling Barge...better to have and not need rather than t'other way round, as the saying goes.

    On the subject of it never rains but it pours…..

    My windscreen which I sealed with liquid sealant last 10days ago withstood torrential rain. Thumbs Up

    Today it’s being drizzling all day…and the headline in the car is wet. Big Cry

    I don’t understand how torrential rain doesn’t get in, yet drizzle does?

    The only potential reason is…on Saturday I did a 3hour drive involving some very bumpy roads.
    Could it have undone the sealing I (thought) I did?

    Seems unlikely, it's silicone sealant you used so it should expand and contract a bit, bumping around shouldn't phase it either. You sure the water isn't getting in via the panoramic roof glass or the sunroof if you have either of those?

    With it being the headlining that's wet rather than the carpets...to me it would seem the water is getting in higher up than the top of the windscreen...

    It’s only wet along one corner where the roof lining meets the windscreen.

    But I take your point… as water finds the lowest point to puddle, I will look higher as well.

    It was just a random thought. If the damp lining is concentrated in the one small area, plus having already been an issue, it's more than likely that you've already found the source of the leak.

    The panoramic roof glass hasn't ever been mentioned as a culprit for leaking to my knowledge, although it's always worth checking...tilt and slide sunroofs are a different kettle of fish entirely of course. Neutral

    This modern design fad of sticking windscreens on with glue has never filled me with deep joy. The old fashioned way of fitting them in place within a rubber seal never caused an issue...but now leaking windscreens with failed or inadequate bonding is a common and recurring problem for many car manufacturers, even on models straight off the production line.

    New technology and design is always welcome, but it should always follow the golden rule. If it ain't broke, don't fix it Wink

    My son's 2018 BMW X3 has had 2 windscreen replacements for exactly the same fault, top edge leaks in combination with failed heating elements and/or rain sensors.

    I put it down to heated windscreens and certain bonding materials breaking down prematurely due to transmitted heat at the bonded edges of the screen...with having almost persistent rain for most of the year in this country, the heated screens are heavily used as quick demisters rather than just for melting ice in the winter. I know I certainly do it.

    Don't know if you are aware of this product.

    I've used it very successfully in the past in a marine environment, quite cheap and very effective.

    A Google search on:

    "Captain Tolley's Creeping Crack Cure"

    Will find it.

    Just to confirm I have no personal or business link to the product.

    Thank you I hadn’t heard of it! Ive now made a note of it.

    Just redone the windscreen in the areas I feel were potentially wanting in sealant.

    I will see if it makes a difference and if not I will get some of that product.

    Thanks for the suggestion.

    EDIT
    In fact….Ive ordered some anyway.

    This impetuous action will no doubt result in the 2 usual outcomes….

    1) My resealing will actually work this time …..rendering the purchase unnecessary.
    2) Having this in my arsenal will deter any other creeping cracks from starting till the end of time. Laughing

    Rolling with laughter Why is it that mariners and Cornish farmers do all the very best names for stuff?

    Oh my sides, I won't be able to stop repeating that phrase for a week Rolling with laughter

    Besides that, I've ordered some to shove in my toolbox, so thanks Phil Thumbs Up ...just glad I didn't have to ask for it over a shop counter Laughing

    Old Tolley only had one leg, that's why he needed to creep everywhere!!

    New regulator got here this morning. On opening the box, I noticed one thing that's been absent from any of the other regulators on the Bling Barge...including the replacement I fitted already on to the LF passenger door earlier this year...the cable on this one has been pre-greased and the unit sealed in plastic.

    The OE replacement I got for the LF passenger door just came loose in a box with no greased cables or plastic packing.

    The cables not being greased on the OE regulators when they're fitted at the factory is why they rust and eventually snap...I coated the cable on the one I've already fitted with lithium grease as a simple preventative measure. So, it's nice to see a cheap Ebay replacement already having this done...

    I'm impressed with the overall quality of this regulator...so much so, I've ordered spares for the LR passenger door and the drivers door to stick on the spares shelf in the garage for when the remaining OE ones eventually do break.

    Total cost of all 3 regulators from the parts supplier in Selby (link in my original post), £182 with free postage... that's around £50 less than one OE replacement regulator from Land Rover Rolling Eyes

    I'll fit the new regulator when the weather calms down a bit...it's blowing a gale and lashing with rain again. Yawn

    New regulator fitted this morning. Straight out and in job, took around 20 minutes. Another plus point over the OE regulator, it hadn't been packed fully extended and the glass retaining brackets were set half way up the runners... which makes fitting the glass into the regulator frame so much easier. A small thing... but a very welcome one Wink

    Recalibrated the windows so the Remote app would stop moaning about them being open Rolling Eyes

    As a small bonus...found a freebie pair of woolly work gloves in the bottom of the box the regulator came in. With the cables and runners being pre-greased, makes it less of a sticky mess handling the regulator when fitting I suppose.

    In direct comparison, having already fitted an OE regulator to the LF passenger door, this regulator was the same if not better than OE quality overall... from the materials, the build quality, the greased cables, the actual fit and the free gloves.

    Definitely worth the buy at £70. Gets a big Thumbs Up from me.

    Hi Mole,

    Do you have the website details of the window regulator suppliers?

    My offside rear needs doing, I think.

    It's just an Ebay shop link...but the company is based in Selby. Really chuffed with the regulators I bought from them as I've said, plus they're the cheapest around that I came across when I was looking for a replacement.

    I ordered from them on the off chance that they'd be as good as they advertised, they certainly didn't disappoint. They also ship same day the order is placed. Comes via the postie too.

    Thanks for that Mole.

    These come with the motor, do you think I should leave the original motor in place, or change it with the regulator?

    At the moment the window opens halfway and stops, on closing it doesn't quite close properly and leaves a gap.

    Is there any grinding noise coming from the regulator? Might just be the windows need calibrating if you can get it to go right up. Chances are though it's a rusty cable that's about to break.

    The rear windows don't go right down on the D5's...so when you lower the window as far as it'll go...release the button then press it down and hold it for 3 seconds...raise the window, release and hold the button for 3 secs...that'll calibrate the window. If it still doesn't go right up, it'll be the cable.

    The replacements come complete with motor so it's just a straight 1 for 1 replacement. I usually take the motors off the broken ones to keep as spares...but it's rarely the motors fail on regulators, it's 99.9% cable failures, all due to the car manufacturers not greasing the cables on them when they build the cars.
