Hi all,

 

My electrical gremlin is back. The front wipers keep coming on without the switch being touched. They run for several miles, stop for a bit and then start up again. Sometimes they sweep for six times or so, stop, then start again. This happened before a few weeks ago and then rectified itself apparently but not permanently. This is happening in perfectly dry weather so I'm not thinking its the sensor but you never know. Its a 2014 Roomster.

 

Just as I was typing this the alarm went off and I see that the door open warning has returned! See my earlier post about gremlins!

 

I'd be grateful for any suggestions.

 

Thanks

There is a plastic bellow that runs between the drivers door hinges, inside here are lots of wires that are well documented to perish and stretch as the door is opened and closed. Over time the wires snap and result in strange electrical gremlins, usually associated with false door open warnings and therefore alarm activations.

 

This wouldn't result in the random wiper operation though, so ether you've got multiple issues or it is something else.

 

Sounds like you need an auto electrician.

Thanks for this suggestion. I ended up going somewhere a bit more sophisticated than my usual garage. They discovered that the pipe taking the washer fluid to the rear wiper had split. This had allowed water to get onto the electrical connections in the rear door and they have corroded. This explained the warning light but also the fault is feeding back to the control unit in the steering column and erratically causing other problems. The diagnostic showed that all of the recent alarms had been triggered by the rear door.

 

Let's hope this is the end of the story!
