Electric step problems (1 Viewer)

[simonjfoley]

Hi everybody, perhaps someone of you can help me with a little intermittent problem I'm having with the electric step in my 2004 Hymer B654 in that, it has lowered and raised itself, on a few occasions, without anyone touching the switch. It has a rocker type up/down switch at the door and an up only switch on the dash. A friend has suggested that it might be a dodgy relay,so,my question is, could anybody let me know where that particular relay is located , so I could replace it. If anybody can help I would really appreciate it. Thanks in advance, ----- Simon.

Probably where mine is - behind the drawer that's below the oven.

Dont know what type of step or switch Hymers have on them, but when my step was doing similar i found out it was a switch that was inside the step housing itself, looks a little like a fridge light switch, as the step retracts the arms run over the switch to stop it from going any further, i changed it in the hope that was the problem and it turned it it was, no more going to step out via the hab door an looking down to watch the step moving back in - switch cost about £10

the switches are also prone to failing

Thanks everyone that replied, I have the main up / down switch ordered at the moment, so I'll try that first and see how it behaves. Many thanks everybody, Simon.

The switch failed on mine , also on a Hymer.. and it's not a cheap item..
I hope you ordered the correct switch for the Hymer.. , it is not simply a rocker switch, it has two small relays on a PC board..

posted about it here

Hi Again,well, my switch arrived and I fitted it, and all worked perfectly until I was out driving the weekend when it played up again, so the problem must be elsewhere. The first thing i noticed was that when I lowered the step when we set up in our campsite the buzzer sounded, even though the ignition switch was off at the time, ( it's only supposed to to go off when the engine is started) Next day when we were driving home the step went down on it's own, luckily the buzzer warned me, then it refused to go back up, so I had to mechanically disconnect it from the motor and tie it up to get home. So now I'm wondering what my next move should be, should i replace the switch on the motor ?? . Any suggestions would be appreciated. Thanks Simon.

triggering by itself whilst moving suggests a short circuit or a bad connection making and breaking the circuit
