Probably a good idea, and not all that difficult, at least on a 126.

On my 560SEL, I had problems with the seat tilt not working.

After much investigation, I found that a busted seat bottom spring had cut through 3 of the 5 wires in the harness going to that motor. The wires were touching each other, the seat frame, etc..... So, maybe check for something like that if you're under there.

Could it be that the relay itself is drawing this 7/10 of an amp? A relay does have a coil that draws current when active.......... Perhaps an internal short in the relay?

See if the relay is getting coil voltage when it isn't supposed to be also. Perhaps whatever controls that relay is sending it voltage when it shouldn't be. I don't know that a relay coil would pull .7 amps at 12v, but it doesn't sound too far off.
