Some things to check if your slideout won’t retract (or extend):

  • Is the ignition on? (for Sprinters, you should actually start the engine to turn off the glow plugs, rather than just turning on accessories)
  • Is the parking brake on?
  • Are the coach batteries connected (In-use mode, not set to storage mode)?
  • Is the slider key turned on?
  • Is the slider button pushed?  Are you pushing it the right direction?  If it is buzzing, then you are going the wrong way. 

If your slideout still won’t retract:  Check the hydraulic pump motor, usually behind the coach entrance step.  Is the power lead from the battery to the hydraulic pump motor making good contact?

    The slides were working fine and now they won’t. No sound from the motor. The red Jack’s light by the driver’s side lights up when we push the slides buttons.
