I had a battery drain problem with my 1987 190D 2.5Turbo... Disconnected the battery and tracked it down with my ampmeter to fuse #12 and the relay for the power seats... I have disconnected the relay, and no longer suffer the battery drain problem, but I need to get the problem resolved. My Question is: Could the problem be with the relay itself? I can't seem to find fault with the seat switches or wiring. Thanks for any input or suggestions. -------Steve.
