THE C350
I would check the control modular under the seat for damaged wires. If everything looks fine I would unplug the modular and see if it stops blowing. Does the fuse blow the second you replace it or does it take time also does the seat work when it has a good fuse in it? Is there anything else that is powered by that fuse?

up date on this its still blowing the fuse some times it lasts weeks
fuse is currently blown and seat heaters work fine
could one of ther seat motors be shorting??
this car has manual controls to move seat back and forth but power for the back and seat height

Best bet is still the wiring. moving the seat around/ changing the position might move the cabling enough to make contact if the wire is worn in any place. doesn't take, but one hair on the cable braid to make contact...
also, search works too.
