Intermittent Fault With Flick Wipe
Posted 14 January 2012 - 10:21 AM
My initial thoughts were a relay issue but the odd thing is that the fault is either present or not - it doesn't appear or clear itself part-way through a journey which makes me wonder if it's a problem in the GEM.
Has anyone else experienced this kind of fault or know what is the likely cause?

My '53 plate 1.8 TDCi Focus (hatch) has just started doing the same thing!
Not had a chance to check into it properly yet (all the usual intermittant / regular / fast wipes work fine) but the one-shot wipe sometimes stalls, then completes other times it just moves a bit and stops mid-wipe.
Thinking back it's done this very occasionally for a while - so possibly a dodgy contact somewhere that's got worse - though more telling when it does work (which it does some of the time) the wipers have to start from their 'fully home' position. Have a look where the wipers 'home' after the wipe (i.e. knock it onto regular wipe - then stop it when the blades are fully parked).
On mine if it's:
- Playing up: The blades park slightly above the black line on the bottom of the windscreen (passengers side is more noticeable) - you can see a gap between the black on the bottom of the windscreen and the 'parked' blade, which doesn't look right.
- Working (which it still does some times): They're parked lower down (i.e. below where the black at the bottom of the windscreen starts) - where you'd expect them to be.
My thoughts so far are:
- Dodgy connection (though unlikely as regular / intermittant / fast wipe work fine).
- Timing / sensor issue - i.e. if it has either different timing or sensor used for the one-shot mode.
- The blades just aren't parked properly period. And whilst intermittant /reg / fast copes, one shot freaks out.
I'm going to change the blades on mine anyway (getting near a new set needed) - I had at one stage thought it might be because there's too much drag on the blades for the ageing motors at least this will prove that one way or another.
If you find anything out or end up fixing it, do post back. Likewise providing the weather gets a bit warmer I'll have a proper look at the w/end and post if I find anything...

When the problem occurred I tried putting it on regular intermittent wipe and that worked ok but the flick still didn't work afterwards, not until after the engine had been switched off. I haven't looked at the Haynes yet but I assume there will be a separate relay for this function. If I get any more info I'll post back.

Been 'flipping cold here late so not had time to do anything other than watch the wipers from within a warm car... Doing that I've noticed when it's playing up - on both flick and intermittant they don't sit properly after wiping.
They go from park, over the screen, back (to park) then move a tiny bit forward (you can really see this on intermittant). If it's in a state so that flick wipe does work - they don't do this - they go from park, over the screen - then back to the same low level park.
So I wouldn't rule out either mis-alignment, or a sensor... Likewise I've got trusty Haynes round here somewhere so I'll have a look through that.
I'm sure between us we'll sort something :-)

It certainly looks like the relay is the most likely culprit.

I had the same problem a month or two ago and just swapped the rear and front relays which resolved my issue.
I had to remove the panel too but it wasn't too much hassle.

Still, I suppose it's no worse than the crazy way you have to dismantle some cars to replace a headlight bulb these days. I think car designers should be made to spend five years working in a service department before they're allowed to get their hands on a CAD system.

Incidentally £24 is a rip-off for one of these. I just checked on an electronic component suppliers website and they have one with the same footprint and similar specs for a little over £5.
