Windows not working on a 1998 Rangie DSE

Hi I have a Range Rover DSE 1998 where the power windows do not work when controlling from centre console or the rear door switches. The fuses are ok. Has anyone had this fault? Thoughts?

The display says "Window not set" but I can't set them as they are completely dead. I have removed the fuse #22 and the display tells me "Fuse 22 failed" so it indicates the fuse is ok.

I've had a failed battery lately and it stopped working after I replaced that (everything else seems to work).

Additional information: when I try to "super-lock" the car the alarm beeps twice. I think it's because the windows not are not set but I am not 100% positive.

Any help gratefully recieved.

Thanks Lee, I searched there already but there was no definitive answer listed. Is there a separate ecu for the windows?

It will probably be the BECM as it's all the windows & not just one. Andy C will be along shortly with a decetn answer!

Hope it's not the BECM & summat cheap.

I know with the RRC it was easy to recalibrate the window travel but doesn't the P38a need to be plugged into Rovacom/testbook in order to achieve the same cos a loss of power is going to fudge the calibration already set and fail safe is not going to let you do owt potentially damaging? Derek

Don't think so.

Would need to look it up if someone wants a definative answer, but something like roll the windows right down, hold the switch down for a couple of secs, roll right up, hold switch couple of secs is the re-calibration procedure.

Similar for sun roof.

Doesn't help the OP, whose windows don't work at all.

Fuse boxes are notorious for corrosion causing wierdness. Have a poke around and see if all is shiny.

Thanks for the thoughts guys, I have fiddled with the fuses and all seems ok (when I take the window fuse out the dashboard complains that the fuse has failed, indicating the fuse is good when it's in. The windows stopped working just after I jump started off my wife's car. The AA bloke said I may have "blown the ecu" when doing that. If there was a Haynes manual for the Range Rover I'd feel more confident diving in to investigate, I foresee a painful trip to Land Rover on my horizon......

There is a better than Haynes called RAVE.

Of course, you should buy a legitimate copy, and not buy a cheap copy from ebay, let alone sneak a peak here.......

The rangerovers.net site is full of P38a info. Use the search function and there are pages of "windows" related threads.

I was hoping somebody had a copy of RAVE NAS to hand? no such luck so I have unarchived a copy and burn to a CD to read it.Afraid there is no mention of the calibration process ( I think you have the procedure for RRC if I'm not mistaken tho' cant check for sure as I gave up the later Haynes with the sale of Peggy ) there is another fuse involved F9 (also supplies power to the amplifier) in addition to F22 to the BECM and a separate fuse for the rear window supply F2 One other thought sprang to mind there is the multiplug the connects to the centre console could that have been disturbed at all ?

OP here (different account) Thanks for that Derek, I'll have a look on Thursday see if it's any of them.

Will post back here the results.

I don't know about the RRC, but after the battery has been disconnected on a P38 you neet to set all the windows and sunroof (and the reverse mirror dip). This is done by lowering each window to the bottom then immediately up again, ie as soon as the window reaches the bottom press the up button till it reaches the top. You should hear a beep and the message WINDOW SET will be displayed. Problems occur with either a faulty BECM or the window regulator being worn, however that would likely affect just one or two windows. They can be a pain in the ar*se to set & take several attempts, especially the front ones, due to worn regulators.

Cheers, Chris.

Thanks Derek, I looked at the switches and there were no obvious signs of faults (loose wires, burn marks etc.). Update: The battery went flat again (had a new battery just before christmas - =A3145 fitted!) so sent it back to the garage. They have confirmed there is a drain somewhere but have not been able to tie it down. (They're getting an auto-electrician to look at it on Tuesday) My gut feeling is the two problems are related and it's the BECM. Are they standard across all P38s? Mine is a 98 2.5DSE and there are a few on ebay ranging from =A3120 (on auction) to =A3500 (buy it now). If they're standard across the range I'm tempted to buy one before the garage tries to charge me full price for an official LR part, which I imagine would bring tears to my eyes. Are they all the same?

Definately not all the same. My SE does not have leccy seats, and when looking at the possibility of fitting some found the relevant connectors on the BECM are missing.

I don't know whether you could fit a top spec one (the Vogue one on ebay for example) to a lower spec car without problems.

Lots more info here:

Search the site for battery drain issues. It's a known problem. BECM can be prevented from going into sleep mode by wireless devices. Have a look at the red light by the gear shift. It should glow dim red when the BECM is still awake when you lock the doors, then go out altogether when the BECM sleeps.

rangerovers.net has a good forum, and is full of P38 advise.
