Soft close doors - S280 (W140)

[graham robert]

The soft close doors on my 1996 S280 dont operate continuosly. The fuse is ok but if I pull it out and immediately replace it, they all work for a few times and then stop working randomly after 3/4 closings. Any ideas what the problem could be?

Got to be a sticking relay?

Anyone else?
