step switch

Can anyone point me in the right direction, please. I own a 2011 nuevo, the electric step has been playing up for a while. Today it stopped, it appears that the round push button on the left entrance has failed. The fuse is good power is getting to the button and the step motor is fine. I an  trying to source a new push button, has anybody any idea's please. ( tried ebay, uk leisure parts without success. Thanks

Surprise, surprise, AS spares dept list 3 different  step switches....order via the online form on the AS website and download the catalogue.

thanks paul, the old style is mine, but just been out to double check with a multi meter and now appears there is no power to the switch. so I think i'm going to have to clean up all around the motor and try again, thanks for your help once more, cheers roger

The fuse for the step is also usually in the em40.

Depending on the type of step you have fitted there is either a separate switch or one integral to the step that determines which way the step motor drives. This switch actuates a relay in the EM40.

These switches are in the worst possible position as regards operating environment (usually right behind the rear wheel). From my experience this is the most likely cause of your problem and certainly not the operating switch which is probably highly reliable. Sorry to be the bearer of bad news - I may be wrong…….

I have no idea what an em40 is guys, help

OK, I have checked the fuse in the em40 and its ok.

The step in our Rienza is a Bain of my life. As said the microswitch on the step frame was directly in line with the rear wheel and all the muck thrown up from the road.
Having moved the switch to the front of the bracket the switch inside started playing up. The problem was loose connections followed by the switch completely failing. The latest issue is it not retracting when you turn the ignition on. 
I don’t know what switch is fitted to yours but ours is a CE one like the rest of the switches in the van. They don’t seem very robust. I now carry a folding plastic step ready for the next time the step fails.

I have now stripped the step down, motor working fine, but it appears that it's the step swich itself has failed. the markings on the cover say Project 2000. doe's any one know where I could buy this switch, I'm not having any luck finding one, cheers.

Is this it?

Also several of the same on ebay, one such...

thanks paul, es hartley, had them but out of stock. The one I need is like a micro switch that the step closes against, similar to a car courtesy switch, but with two contacts, thanks for your help though.

This may be it!

Thanks for trying, but sadly not, I've found something similar on ebay, the trouble is I don't think this is the problem, when I got the multi meter out I tested the interior push switch connectors and found this is only showing 4 volts, I then tested the step switch and that is showing .16 volts. I then took the 20 amp fuse out of the mb40 with the step in, when I put the fuse back in the step came out, but on pressing the switch inside it  would not return and there was no sound in the motor, I can  only assume that some where there is a voltage drop in the system, next try is to take the motor off, but if the step comes out on replacing the fuse the motor must be ok. I'm baffled with this, cheers.

Sorry em40

Check the connectors beneath the EM40, make sure they are secure and not melted.  EM40 is secured by four crosshead screws, one in each corner, remove screws and gently prise up and twist to retract, the cable loom is quite long.  There is tons on info on this site about dodgy EM40 connectors and replacement units.

thanks, just been reading up on the problems, so that is definitely the next avenue to explore

Just checked the fuse slot in the EM40, there is over 12 volts passing through it, also checked the rear of the EM40 and no burn marks. I can only assume there must be a bad connection on  the motor.

Does the fuse slot grip the fuse tightly, a loose fuse can cause a high resistance and a voltage drop.

Hi, dont bother with other things its the micro swich on the step,blooody nightmare! If the step is in leave it alone as otherwise the alarm sounds when you try and start the engine ,why o why so complicated for just a step!  best of luck   Paul 

As others have said the steps can be a bit of a pain when they go wrong. The microswitch on ours works now sounding the alarm when you turn the ignition on with the step out.  Unfortunately since our overnight pub stop the auto retract has stopped working again. 
I sorted this problem a year ago by changing the relay behind the fridge. Until the weather gets warmer it can stay as is. 
I can manage without the step going in but coming out is a bit of a drop for my knackered knees. Management and muttly need a step both ways. There are some newer coachbuilds with a built in lower step but not Autosleepers.

thanks for your advice all, the sergeant, is I believe a 258, i'd have to check the manual. Dave is the relay easy to get at, can I access it via the fridge vents or is it fridge out. I've just had a step switch delivered, but will try it when this rain stops. Cheers

I don’t think the wiring layout on yours will be the same as our aged Rienza. The switch on ours is on the panel between the door and the fridge. The relay is behind the fridge vents hence the connections being corroded last time it failed. 
As much as the older Autosleeper are simpler electrics there are some things that are not very well thought out or meant for long life.
