How To: Remove Seat Backs on 2010-2012 Cars

Ok so the wiki page and video on YouTube are of earlier cars and as I found out when trying to diagnose a peltier unit fault with my seats, how to remove the back differs to earlier cars.

So, here's the how to *WITH THE SEATS IN SITU*

Time: 1 hour 30 minutes

Difficulty: Medium

Tools Required:
Long flat bladed Screwdriver
Ratchet with T20 and T30 bits and 10mm and 13mm sockets
Screwdriver with T20 bit

Step 1: Lower the seat to remove the inside screw

Contrary to what you might think, you need the power still on for this first step.

Lower the seat to its minimum height and put it as far back as possible. Here you will be loosening the screw on the centre console side of the seat trim. Lowering the seat and putting it as far back as possible makes this screw easily accessible. It's a T30 bit.

Step 2: Move the seat and cut power

Once you've got this screw out, move the seat as far forwards as possible and as high as possible.

Then follow the instructions inside the bonnet and remove the negative (M10) and positive (M13) terminals from the battery to cut power. Remember the seats have airbags in and you'll be working right next to one of the sensors.

Step 3: Remove the outside seat trim

Remove the seat belt anchor point trim. This pulls up slightly then out.

Under the seat are 2x T20 screws to remove. These are accessible with a ratchet.

Now, the seat trim will gently pry off. There's a panel clip at the back, middle and front so, focus any pressure on these areas.

The panel will then pull off. There's no need to remove any cabling.

Step 4: Unclip the rear pouch and remove the white joining trim

This is quite simple. The rear pouch just has some bungee clips underneath to undo.

Stow out the way like this:

The white joining trim will bend easily so, this is a simple step. See the back of it as to how it fits:

First, unclip the tab at the top on both the left and right. Then just bend the white plastic and pull it out of its channel on one side. Then it will simply pull out the other.

Step 5: Remove the rear panel

There's a couple of steps here. First you need to remove the panel from the spindles on either side of the seat:

Just flex the panel over the spindles.

Now, the panel is ready to be removed. Start firmly pulling downwards. There is a tab on either side at the top. You'll need to pull it a good 7cm or so before the panel is clear of the tabs.

Once free, you'll need to do a bit of hokey poker to get the panel free. Release the outer side first then gentle manoeuvre the panel to get the inside clear and the panel will pull out.

Step 6: Accessing the Peltier cell screws

This is the view you should now have:

First step is to unplug the multiplug - just push in the tab and pull.

Next step is to start removing the cell. First, unclip this wire:

Now unclip the trim on the lower side of the air intake:

Now unclip the seat base stretcher (the screwdriver will come in handy here, as it needs a fair amount of pressure):

Step 7: Remove the Peltier cell

The 3x T20 screws should now be visible. Remove these.

Now unclip the two clips at the top of the Peltier cell:

The unit is now free - there's a fair amount of space so should be easy to remove for replacement or repair.

And now just the reverse for refitting!

A note when putting things back together, the inside trim may need putting back into position. Just reach in and move the tab back inside the frame of the seat:

Brilliant write up. Thanks for doing this. I’ll definitely be using it soon as I’m convinced my seat isn’t cooling as it should be in the seat back.

For seat heating/cooling diagnostics, the below is hidden in the workshop manual:

Then follow the diagnostic tests A-D as the above reference table identifies based on the code you get.

-------------

My symptoms: cooled seat works however heated seat does not operate and once activated, cooling will not work either. Requires a battery reconnect for cooling to start working again.

My IID tool was giving me the following error:

Following the above diagnosis guide, i should be looking at tests C for correct resistance of each unit and at the blower and ducting assembly. As you can see from the guide, there are other errors to do with open loop, current draw etc if the units were to fail and as mine specifically says seal leak, I have started with the inspections of the ducting and then working my way back to the Peltier units.

After removing the back unit for a thorough inspection, the plastic had plenty of flex, there were no cracks anywhere on the assembly and the fan functioned correctly. The unit also looked fairly new and, there was a sign the pack has been taken off the seat before so, I suspect this unit has already been changed in the the last few years. On this basis, I didn't feel resistance checking was necessary and to focus investigations on the base unit. Accessing the seat base is actually much easier. I'll write a short guide but it's actually just 4 bolts and all you have to Then do is tilt the seat backwards or forwards go access the underneath. 2015 Range Rover Autobiography 4.4 SDV8

That's exactly the same construction (and method, except I left the outer trim in situ) as my 08MY.

2012 Range Rover Westminster 4.4 V8 Zambezi Silver

Hi guys

Im in the middle of sourcing parts and trying to fix a few issues with my new to me RR Westminster

One of the issues I want to tackle as its cold is the heated seats. I see on another post Jag XFs might have the same unit to fix the heated seat not working.

https://rrr.lt/en/used-part/kdd9771-l00849...fan-blower

This is a link for a Jag XF complete Peltier unit with the same model number L0084982 but on pictures above the land rover one has AD07 after the model number where as the Jag one has AD05

Is there any chance this is the same unit or would have at least the same insides as 2 of these would cost me 180 Euro where as 1 unit onlibe is 500 euro or for the plastic and Peltier its cost me 400 euro delivered and customs.

Im sorry if I am repeating prvious questions or posts its just I amd trying to read 70 pages of posts relating to all my issues!

Yes, it's the same unit. Part number is HHK500060 on all 2002-2012 cars with heated and cooled seats. Only the peltier cell needs replacing, unless the ducting is damaged, or the motor isn't working.

There's supply problems on them at the moment (including to Land Rover themselves).

If your seat blowers continue running on cool but trip out after a few seconds on heat, you can almost guarantee its the rear peltier cell. To confirm, remove the seat back and disconnect the multiplug. Then put a multimeter across the blue and the yellow cable. A healthy unit is around 10ohms. A faulty unit often reads around 1kohm. 2015 Range Rover Autobiography 4.4 SDV8

Thanks Gary

Ripped the drivers side and even though I have an intact duct (might be a revised part as the rubber/plastic is soft) I'm afraid I do have 1.4komh across the blue and yellow.

The only source I have seen on here is JNC but that costs 150 sterling which will be around 220-240 euro by the time I convert to euro, delivery and customs here.

Have we any other site source for just the peltier unit at present?

There's a shipment due at some point in the next few weeks, so if you can, hold on for a bit. 2015 Range Rover Autobiography 4.4 SDV8

Ah ya its not vital, no harm in learning how to rip the unit anyways. The posts and pictures on here were very helpful.

Is this shipment the ones that cost £150 for the duct and peltier? Current yokes

Huge thanks to the original poster. I have just replaced the Peltier element on my 2012 and these instructions and pictures were so helpful. Everything exactly as explained. It took me longer than the 1.5 hours as I learned what to do, but a second one would be about that time. Regardless, these instructions saved me hours. Thanks again. Oh - and my passenger no longer complains about the lack of warmth! 2012 Range Rover L322 Westminster TDV8
