I have promise myself this winter I will get around to sorting out some heating in my Sports Leather front drivers seat,so earlier in year I bought a set of Waeco heated seat pads to refro fit.
On closer carefull inspection today of the existing seat wiring fitted to the seat it appears ther are just 2 wires...Blue @Brown..which I assume is a 12v+ and a 0v- and when the dash switch is opperated it forms the circuit and the elemnts in saet heat.(well not so in my drivers seat 0.
The kit comes with its own wiring loom and switches and a relay telling me I require ignition 12v+ and a constant 12v + along with its own 0v-.
Would I be wise using the entire kit with its own switches which have a 2 phase setting..Low/High and just ignoring the existing dash switches or should I ignore all the wiring loom and switches provide with the kit and just hooking up power and earth wires to the existing seats loom ?
Anybody done this retro fit before could advise,would be helpfull.

I would say use the existing vehicle loom and graft on the connector from the old seat heater to the new pad.
The variable heat setting on the new pad makes me wonder how they are configured, though. Do they have a controller that adjusts the temperature or are there perhaps 2 elements in the pad, of which either one or both are activated?
I can't remember if the PFL system has variable heat settings - I know the facelift does, but if it's a straight on/off is it going to burn your @rse if you wire it up permanently on full heat and ditch the switch that came with the pads?
I certainly would avoid using the switch that came with them in favour of the original setup, but it's just a question of how the high/low power switching works. :-/

your call ;)

.. and current weather conditions are making me wonder if these pads will fit a Westfield seat. ::)

They're just on or off ;) ;) base & lower back wired in series with other.

Now you know what happens when you take that out on a cold day ;)

Unsure if there is any fancy dual elemnt within the pads.
The switch just has a Low/High setting which says either 44 watt and 90 watt .
Existing Omega dash switch seems to give just an on/off facility so unsure if the retro seat pads will be on Hi or Lo if connected via existing cars loom.
Logic says there must be a thermostat in the pad which cuts off the power so doudt if my ar...e would catch alight.

Now that would be a good idea, and stop those constant holes being burnt in the seats....

I thought there was ....... there's an Oxo sized bit of electrickery that I'd assumed was a 'stat. Lincs Rob seems to be the heated seats man :y :y

If you can recall,the heated seat plug under the seat on m/f seems to have just 2 wires..think its blue/brown from memory.
The wiring feeds I seem to have on the retro fit heated pads from Waeco have 3 connections.
1...to a permenant 12v +
2...to an ignition switched 12v +
3...to earth.
If the existing seat wires were connected up to the new loom I expect that the existing feeds must be earth and a switched 12v + controlled by the seat switch on the dash panel.
Would it then be just a case of connecting the remaining new loom wire to a permanent 12v+ as the new switches allow for 2 heat settings.
What I would really like to acheive is being able to switch the existing dash heated seat switch on the dash which gives power to the new switch and then fit this new switch to the seat edge allowing its duel function of heat and still retain the original appearance from the dash.
Does this seem doable in your experience ?
-
The Waeco kit is a complete fitting kit which contains a relay to switch the 12v feed hence the need for a constant and switched 12v feed.
This is already built into the car so you can remove the relay from their loom and wire the connector under the seat directly to the pad (plus temperature control gubbins). :y
EDIT: why not leave the High / Low heat switch dangling under the seat so if it's too hot on the high setting you can switch it to low?

Thanks Kevin.
Easy when you know how !!..so really the operation of the existing heated seats is just 2 wires...1 a 12v + and the other an earth and the car switch just forms the circuit.
Looks like the worts bit then is getting the heated mats into the seat,but that may well be somebody elses job...see how the £££,s go.

although there's no guide, it's quite straight forward, hog rings at the very rear of the base, the sides of the base just have thick card stitched to them and you just push downwards (the direction you would if sat on them) & then they pull out of fabricated 'slots' on the side of the base seat frame. You won't need to fully remove the covers from either the base or back rest if you're just slipping heater mats in there.
I'm sure there was a picture somewhere ...... had a look but can't find one :-/

Sorry for the thread hijack but don't think it's worth starting a new thread...
My drivers side heated seat does not work, fuses are ok, is there something on them that burns out normally? Would I have to replace the whole heating element?
Cheers,

Heated seats seem to be a constant topic on the forum as they are prone to failure,especially on the leather seats.The most common failure is a break in the wiring inside the seat base or back pad causing the entire circuit to fail as becomes "open circuit".
Some have managed to repair the break in the wire with a piece of wire soldered in place but the biggest problem is locating the break.If on fabric covers it often burns through so you can see the damage area and carry out the repair.
Bit harded to trace on leather..you can do a test on the wiring with a meter and atleast establish if itis the back element or the base but again seat needs some dismantling.
Leather seats seem to be more prone to breakage as expect caused by kneeling or weight being applied onto the seat pad.
I have decided to use a proper retro kit from Waeco as their elements are much stronger than original GM and also a lot less money ..only issues are bit of extra wiring which thanks to several people have now steered me in the right direction so hope to have a warm seat sooner than later this winter.
My leather seats are MV6 sports so may have a few more issues and will not be able to get a heater mat into the thigh bolster as original,but small downside.

Thanks for the reply Amba, I will have a look and see how easy it is to take the seat apart!
-
Are yours standard leather or sports style ?
Somewhere on the site is a set of pictures of the seat dismantled and shows what is involved.
By all accounts they are very heavy and due to air bag issues require battery disconnecting atleast an hour before you start unplugging anything.
Then I think its just grit your teeth and have a go..trouble I have is car can,t be off the road for too long as my means of work transport.
-
The car has the standard leather seats. I will have a look see if I can find some pictures.

Hi, Did anyone find the diagrams for the heated seat dismantling. Preferably idiot proof if possible, especially if it involves making sure you don't set off the airbag by mistake..... Saw one article that said someone broke their arm setting one off, but unfortunately didn't tell you how not to..... And no smart comments about keeping your arm out of the way lol Thanks!! Edward.
