The fuse to the step on my 1999 Hymer intermittently blows, the current draw when step is operating is around 10 a when the step reaches the end of it's travel the motor continues to engage and current shoots up to around 20a (I can see this by checking on the panel) The 15a step fuse also feeds some other lights and it looks like if any of these lights are on the combined current draw blows the fuse. If nothing else is on the fuse is OK despite the control panel showing a 20 a draw at end of step travel.

Will get an auto technician to look at it as soon as I can (not hopeful!)

In the meantime anyone experienced this? the step is clean and travels freely.

Need to get it right as have someone interested in the van

On my Hymer, the step motor only runs when you press either the up or down button..
there is no 'end of travel ' limit.. and it would blow the fuse if you continually held either button after the step had reached the end of travel..

.. perhaps yours is different.. ?

I recently had to replace the up/down switch on mine

Right, sounds like mine is the same, may be OK then?

what were the symptoms that caused you to have to change your switch Jim?

My step has an intermittent fault. It's supposed to retract when the engine starts but sometimes doesn't.
I have traced it to the "travel limit switch" which sometimes fails to make the contact so the motor fails to bring the step in.
This switch is there to stop the motor continuing to run after it is retracted, so yours may be a similar device that has gone wrong in the opposite way, and the motor doesn't stop.
