ANyone had this problem? Neither the seat or the seatback work - I assume they are different elements, as on another car I own (Merkur XR4Ti, FWIW). That tells me it is most likely before the seat. So, I pullled the switch panel off, and check both sides - the switch seems to be fine, too (the passenger seat works - so it isn't the fuse, either). Is there a relay somwhere for these things, does anyone know?

Thanks!

I've got what appears to be the same problem (with the drivers seat only as well). The shop claims it is the coils in the seat, not the switch, etc. Were you able to correct your issue and do you know if the coils user replaceable and where you might find comparable ones?
