My drivers seat heating has stopped working.
After quick check with resistance meter I have discovered very high resistance (few kΩ) in the drivers cushion element, backrest element was still okay (few Ω)
Next thing was to carry out some research and establish faulty component part number.
It wasn't easy as I was getting different part numbers from different sources so I decided to strip the seat base.
My seats are Alcantara and the cushion is designed so the heating element is sewed together with the upholstery.
And now the best part, the cheapest upholstery with integrated heating element would cost me €520=£440 or repair kit (heating element for cushion and backrest) €220=£186!
This was still way too expensive in my opinion so I kept on digging and eventually I found brand new cushion only heating element for €48=£40.
The only problem was that it was for fabric seat and not leather type one.
After comparing the wiring diagrams for fabric and leather seats I came up with the conclusion that they are the same in the sense that both heating elements (cushion and backrest) are connected in series but the interlinking plug/socket are different.
So after spending €48=£40 and crimping my old plug on my new cushion heating element I now have fully working heating seat back again
