Ah good knowledge. I just copied the part numbers from another car with the same interior, Fitted fine.
I think the whole thing cost about £400 which is similar to the option cost but i didn’t realise I hadn’t optioned heated seats until too late in the ordering process to add them so this was my best option. Probably 4hrs per seat and another 4 hours for the wiring as I had a bit of problem solving to do to locate and access the AC Control module. Usually someone on YouTube has trod the path before you, but not so on this project.
I understand your point of view but the car is just a tool to me; it’s there to be used, it’ll have 100k on it by the time I part with it and quite enjoyed the challenge. There’s also the fact that seat heating uses less power than space heating so there’s actually a range advantage to be had too. (Probably…….)
