Retrofitting heated seats (W203)
- Thread starter acf8181
- Start date
Well you have touched on a subject that has a whole lot of mystery about it,we do have a couple of members who have retro fitted heated seats,look on the past posts,according to companies who retro fit these seats there is nothing in a car that does not have them fitted at the factory,and so they talk telephone numbers,I remember a quote of £2000 for my car,I suppose it is how they pay the mortgage ,I have always thought that nothing could be easier,heated seats need power going through a fuse and some means to limit how much your seats heat up,if you do not mind coming away from the factory fittings then there are a number of companies offering a complete heated seat package and quiet cheap as well,but it will mean the seats have to come out ,again there are past posts on how to fit the heated pads to them,best of luck.

In a 203 the heater elements are sewn into the leather covers, so you would need need seat covers. You would also need the wiring looms and control pack. The buttons are part of the control pack, so the existing bank of buttons will need to be ditched. All do'able but as already said, expensive.
Far easier to go aftermarket, with separate heater mats under the seat covers. I had the rear seats in my 203 heated and they worked very well, in fact hotter quicker than the factory heated fronts.. IIRC only cost approx £200

The harness is ~£60 special order from Germany, I bought one but gave up the project so you can have it for £40... it’s in storage so I can get someone to collect and send it to you if you like.

That's the harness I need for my seats as the one I purchased is a different plug setup. Are you able to PayPal invoice me? Happy to cover the sellers fee at this price, thanks.
