pull the seats, clean and grease the geared tracks with a heavy grease (I use green waterproof/marine bearing grease).

there's a mechanical failure mode that results in poor seat movement... each motor has a bowden cable coming out of it, for the far side of the gear tracks. this cable has a square(?) end that fits into the motor, this can strip. amd the symptom is only one side is driven, and the seat gets a little sideways in the track and jams.. one fix is to take it all apart, cut the 'sheath' (tubular) part of the bowden cable down 1/4" or so, so that the square end fits deeper into the motor, and reassemble it all.

 

That's good to know if the time ever comes. Mine actually creak and groan when they're not moving, just when I'm sitting and slightly shift right or left. I thought a little silicon spray would temporarily quiet things but I don't know if it might cause a short?

 

silicone spray won't short anything, its non conductive, but its such a light weight lubricant, it won't do much good for load bearing metal-on-metal. also, Silicone has a nasty habit of being impossible to clean off, completely invisible, and repels things like paint, wax, and leather treatments, so any overspray is quite likely to get places you don't want. silicone gets on your fingers, then leaves fingerprints, and 5 years later you repaint and those fingerprints mess up the paint job.

creaking/squeaking when you sit in the seats, thats probably plastic-on-leather... take off the trim bits on the sides of where the seat back joins the seat bottom, and apply some quality leather treatment thoroughly to the leather, then replace those plastic bits. and as I said, when you have the seats out of the car, clean and thoroughly grease the rails with green marine bearing grease or similar (I would NOT use a black moly grease. maybe a white lithium grease would be good?).

 

Good tips, thanks
