Heated Seats - Land Rover Forums : Land Rover and Range Rover Forum

So, now that winter is approaching, I'd like to get my heated seats working.. Of course, neither seat works. The ironic thing is that the heated seats in my '88 Saab convertible work, but I'll never drive that in winter...

I'm pretty handy with a multimeter and electrical work. Problem is, I can't find any of the how-to guides or wiring diagrams that I found last time I wanted to fix this problem (over a year ago).

Obviously the fuses are fine (that would've been too easy!) and the lights come on the buttons when I press them.

If anyone could point me in the right direction, I'd really appreciate it.

I am at work, right now, when i get home tommorow, in the evening i will look in the book, and see if i can assist you in anyway.

Try here:

Heated Seat Repair Operations

light at switch, and fuse fine, sounds like either relay or the element. with a Calssic, I always presume relay first.

Thanks for the help... i'll check out the relays when I get a chance and post the outcome.

Cap-Pig, any tips or pics would be nice. Mine are in need of repair too.

Hey Series1Rangie, if I hear the relay when the seat heat button is pressed does that mean the relay is working, or not necessarily?

I can't hear any relay clicking. I was just out looking for the seat relay and realized I haven't a clue where it is... I can't access the RAVE CD because my only Windows-based PC is broken right now. Can anyone tell me where the heated seat relay(s) are/is? I see plenty of relays underneath the seats but have no idea what is what. Thanks!

land_rover service manual

now you don't need a PC.

Well thanks. I'll see if I can understand the manuals and perhaps, try working on mine in the future. thanks again

cap-pig · 10-02-2009, 08:55 AM

I have that service manual that you linked to, but it does not have the electrical diagrams that the full RAVE CD has on it. There's nothing in there that has the relays in it.

So I know this thread was from three years ago... I'm trying to fix my heated seats again. I've searched and I have the ETM. The relays are underneath each respective seat.

I also read the RangeRovers.net article on how to bypass the lower cushion so that the upper cushion works. Unfortunately the instructions seem to be P38 specific. Is it possible to bypass the lower cushion on the RRC's and if so, how?

cdb · 10-22-2012, 09:48 PM

I think there are only lower cushion heating elements in the RRC

cap-pig · 10-27-2012, 06:49 AM

Nope, because there are definitely wires leading up into the seatback in addition to those on the seat cushion. It's just that they are wired in series, unlike on the p38 where they're plugged in separately. Maybe if it doesn't rain today I'll go out and give some things a try.

Hey Cap ... i have the exact same issue. Thought id tackle next (just pulled my radio and sub to send to roverville).

Did you come to any conclusions?

jkleev2 · 01-28-2013, 09:53 AM

I have the same problem... I have the service manual on the computer and looked the fuses under the seat that are supposed to be the heated seat ones. All of them were fine and neither of them work still. The passenger side button will light up but won't turn on and the driver doesn't even light up. But I swear that if I hit a bump in such a way they come and and get very hot very quick... so i usually get them when I don't want them. I don't really want to pull the seat apart and I don't really even know how to go about doing that. Any simple fixes anyone has found??

cdb · 01-28-2013, 05:49 PM

If anyone can describe the seat heater relays and their location and/or include a picture it would be very helpful.
My 1995 RRC shows the button lights on, fuses are fine and I even have 12v power to the plug underneath the driver's seat that connects to the wire from the heating element. Still, neither seat heats up.
Both of my heating elements are new.
