Heated Seat connectors?

[surfingooner]

Are these the connectors for heated seats ? So I just need the switches ?

Matt.

The brown one is for the seat heater

Thanks Sierrafery, So that’s is the only one required ? Do I then need anything else other than switches ?

I assume the photographs are of underneath the seat. If the heated seat connector is there then I would assume the heating elements are installed but I can't recall how they are connected from my previous repairing them so don't take that as a garantee - I know that the back and base elements are seperate so they must join somewhere - they work in series as if one fails both stop working. Be aware that the elements tend to get damaged after years of entering and exiting the vehicle and squishing the seat base. So if they are installed and have been for sometime then they may not actually work when you want them to. They're not that cheap to purchase replacements and genuine seems to be the only supplier.

The switches go on the panel with the power window switches. Can likely be sourced easy enough at a wrecker or on eBay, particularly from the USA for cheap. You would need the correct harness to connect the switches to the seats too. Maybe it's already there, I think a lot of the wiring looms on the D2 includes the wiring for all the top options?

No they are in all models AFAIK.
My 2002 next to base model has them. It says on Revs certificate model LT. It had cloth seats non heated.
I use them for the electric recline on my Recaros.

I have a base 2002 with cloth seats when new. I put HSE seats in. Bought the switch panel and 2 switches as a kit on Ebay. Winter mornings are a thing of beauty. The HSE seats have warming pads up the back quite a way too...so not just base. I likee a lot. Cheers

Oh...when I put the leccy seats in I also needed to use a Nanacom or similar to tell the BCU the vehicle has leccy seats...cheers

Yes, BCU programming is needed for electric seats operation but not for the heating circuit, that's not BCU dependant

[ozscott]

I would have expected more support from my fellow Western dweller Pedro...bet yours are switched on! Are you using valet mode? [emoji847]

ive got heated seats in my d2.
there is nothing better.

Thanks for the replies, yes there are the two plugs unconnected where the window switches are. So trying to work out what is needed other than the switches themselves ? I am guessing that something still needs to attach to the plug under the seat, but a couple of videos on YouTube, ie British Atlantic, say you just need the switches and new facia panel. I think I still need something more ?

I just got the car back after two months of drivings the wife’s XC90, a friend I often give a lift to has commented how nice the heated seats are, so I have to settle this as I am not going to let the Volvo have something over the Land Rover !!

nope that all you need.

For the switch side, it's just the two switches and face panel that you require. Easily source from a wrecker or eBay, particularly the USA for cheap.

For the heating side you'll likely need the actual heating elements as if you have low spec seats these won't already be fitted in there - two per seat, one base and one back. Likely around $150.00 AUD + each. You'll then need to remove the seats, remove the fabric covers and fit them and reassemble.

Then your good to go.

I bought the switches off Ebay a few months ago and after reading this thread made me get my butt into gear. Took me a whole 10 min to do the job. They work brilliantly. And warm up very quickly[emoji106][emoji3]

Thanks Sprover, even my colour facia plate too !! I got to briefly put a switch in from another Disco last week, the switch light came on, but no heat after about a minute.

We weren't sure which seat it was for and maybe it was driver and didn't work, but the fact that the switch light came on, does that mean everything is already connected ?

[Eevo]

but no heat after about a minute.


how did you test it?
putting your hand on the seat isnt enugh, sit on it and go for a 10min drive.

[surfingooner]

I didn't have enough time as I was picking up a part I had bought and he had to be somewhere, so we did a quick change and fitted a switch in the hope that we would notice some heat. It was very difficult to tell if it was body heat or the seat was warming.

[Jazzman]

I fitted some to my car, but only the passenger side works. Truth be known that is the important side. I assume I've got a relay issue or the element is buggered.

[twr7cx]

or the element is buggered.

This is more likely. The base element usually gets damaged on the door side from being pulled and compressed when entering/exiting the vehicle. If you remove the seat material you'll probably see one or more black spot where it's broken the connection and sparked/shortened a few times.
Due to being wired in series, if either the back or base elements fails the whole system won't work. Both need to be functional for it to work. They're not cheap to replace (e.g. compared to the price of a complete electric blanket for a bed) but worth it in my opinion.

[surfingooner]

Still bloody freezing in Melbourne and found myself some switches today. Fitted to both sides, but no toasty bum !! Someone mentioned that I will need to activate them to the BCU, but cannot find anywhere on the Nanocom where I can do this ?

Else whilst all the the connections are there, is it possible some of the wiring is not. Obviously the connectors are there for the switches, but never found any relay under the seat ?

Any pointers very welcome.

Matt.

[sierrafery]

For the heating elements to work no programming is needed and no dedicated relay involved, fuse F15 interior fusebox gets feed from the auxiliary circuits relay(which is for many other things too) and it's passed through the switches directly to the heating elements, simple as that(provided we speak about manual seats)

Interior lights and cigarette lighter working, and the lights on the heated switches are on, so think all in order there ?

Is there anyway I can use a multi-meter to check the current or find out what is missing or not working ? Brrr. Matt.

[sierrafery]

Measure at the switches to see if you have +12v against ground on the green/white wires and if yes in the brown connectors under the seats on the blue/... wires

btw that F15 is only for seats

ok, tested wires as suggested, both ends and 12v present, I keep thinking I must be moving sing something to connect up? Thanks for your help with this. Matt.

[AK83]

So do your seats have the brown male plug fixed to the seat base, for the brown female connector to connect too?

I had a peek at my brothers old '02 model seats and they don't have the seat element connector(brown plug) on them.
One of the seats was stripped for the cloth material, and no element in it, nor the male connector clipped to the seat base.
My part car is a '99 model, we used it's seats to make nicer seats in brother's '02 model.
All the loom stuff is there in my '99, as would be expected.
Can't remember is the '99 model seats now in brothers car had the brown plugs.

so when you say 'both ends' of the wires, do you mean both sides ?
or that you definitely have the seat connectors, and hence both ends of the two connected brown plugs on each side?

in your first post, you show the photo of the brown plug. That looks like the loom plug(from switch to seat). Photo doesn't specifically show it, but I can't see the seat plug that the loom connector plugs into.

[sierrafery]

If 12V is present at the switch then after you latched it in the feed must get to the brown connector under the seat on the blue/grey(LH) and blue/pink(RH) wires and you must get 12V across these blue wires and black in the plugs

[surfingooner]

Thanks Gents, I think this confirms I am missing the female connectors which come from the seat, which then spells trouble. I will have another look to confirm soonest, but if this is the case, then does it mean no heating element was fitted.

There was 12V present at the switch in the centre console, and 12v at the blue / white wire at the male brown connectors under the seat. So all the wiring is there that end, but it now needs to connect to the seat itself.

Note ideal then. Fingers crossed I can find the female connectors hidden somewhere I so far have missed.

Thanks again for your trouble helping out.

Matt.

According to RAVE, the seat connector is clipped under the seat on a cross brace type metal thing, so it may not be obvious if you just have a peek.
Same brown style connector as the one in your photo.
I'm curious as to what your black connector with the red and black wires is for.

The yellow connector is the seat sensor that tell the BCU that someone is present, disconnected will show a warning sign for the air bag or something similar.

[surfingooner]

Just tried to have a look again, and from passenger seat stuck my hand between the metal wires and the stuffing and got my hand stuck, could not pull my hand out as wire stuck fast against my wrist. Was stuck there for 15 minutes and eventually in a bit of a panic as I had obviously cut off the blood supply to my fingers, being on my back also limited options somewhat, not able to get another hand in there to help.

called wife for SOS, and then eventually managed to wedge a pen in sufficiently to squeeze hand out, lot of pain and felt like wire was about to cut through my wrist and would
be done for ! Amazing how quickly a small problem arose and the developed into a big drama. wrist now very sore and still have pins and needles in fingers, 20 mins have passed, keeping them moving.

Will have ave another go later, will now try and see if I can find any photos of what I am looking for.

[ozscott]

Christ mate. Not good. Cheers.

[surfingooner]

All better now other than some damaged nerves which will heal in the next few days.

Would anyone with heated seats be able to post a photo of the connectors from the seats ? Where do they come out from under the seats ? That would be a great help.....

[surfingooner]

Still no proper feeling in 3 fingers, damaged nerve which doc tells me will get better eventually. Next step is to take my seat out for a proper look at where the seat connectors should be, but refused to be beaten now I have the switches ready to go, so if someone would kindly post a photo of the connectors from the seat and where the wires come from under the seat, that would be hugely helpful. Bit f a palaver this one for what I thought was going to be a simple project. Matt.

ps I have googled lots of images to see what the connectors look like and where they come from and cannot find anything.Cheers, Matt.

That would be great, thank you. Happy to pop over at a time convenient for you.
