Driver power seat won't move

Seat doesn't move in any direction, or only some directions.

R107 power seats use individual motors per axis (fore/aft, height front, height rear, recline) controlled through a switch pack. The power feed is fused at the seat base.

What the diagnosis checks

  1. Does any direction work — fore/aft, lift, recline?
  2. Any sound at all when you press a switch?

Possible causes it points to

  • Single motor or switch failed
  • Seat motor relay
  • Seat circuit fuse blown
