Just recently front wipers and washers won't work unless Yeti 1.2 outdoors is moving .  Even if parked with engine running , they won't work , though rear will.  Tried opening and closing bonnet ( saw this on another thread , in case ) Fluid in washer, plenty battery power Any ideas

Thanks .

All my Skoda (2x Yeti and a Fabia Monte) so far have wipers that slow or stop when coming to a rest.

 

I have a 2015 Elegance and wipers work as expected in Auto and Manual while at rest.

Do you have maxidot. Does the bonnet show open when the wipers won’t work. Does sound like the bonnet open switch could be faulty.

You know, I'm not sure if I gave Maxidot .  Ex use my lack of knowledge , but how would I check if my model had that ? 1.2 Yeti TSi Outdoor SE ?

Do you have a display between the speedo and Rev counter like this that shows doors/bonnet/ boot open?

The display in photo is showing bonnet and boot open.

Thanks. In meantime I found same.   I did open and re close bonnet a couple of times but no change so as you say switch may be faulty.   Though it does seem strange that the wipers work fine as soon as you're on the move .  You'd imagine the sensor was to prevent wiper use when bonnet is open.  But appreciate wiring set ups sometimes do funny things . Saw a post somewhere suggesting checking fuses , so I'll try that in day light once I've found a fuse diagram and fuse number .  Cheers for comments so far

I think the logic is that nobody usually drives while bonnet is open, therefore wipers are allowed to work even if bonnet sensor doesn't function. 

You're probably right.  Trip to garage , I'll post outcome 

If it was a bonnet switch issue, the cluster would either show the door open light or the image above to warn you.

If it was a fuse, then the wipers wouldn't work at all.

 

Anyway, pretty sure this is normal behaviour.

 

It's identical to what I remember happening on my MK2 Octavia which is the same platform and electronically very similar. The wipers would work normally when driving but when stopped, they would pretty much stop and only do a very occasional wipe. The Yeti manual states the wiper interval is speed dependant. My old Octavia manual goes one step further and states that below 4 km/h, the wipers will switch to auto/intermittent mode, it'll revert back to the correct interval at above 8 km/h.

 

It's easy enough to test the wipers, turn the car on and have the wipers enabled then have someone spray the window with a hose pipe. I'm pretty sure they wipers will move just not as often as you expect.

 

I certainly can't think of any obvious failures that would prevent the wipers moving only when stationary...

I don't have auto wipers so cannot do the hose test .  No lights warning.  Wipers do work when moving.   It's not really a wiper sweep interval that's the issue, it's no wipe or ' jets' to the front unless in motion. 

 

I had the car for near 4 years and most definitely have I used the washers and wipers when the car is stationery in the past .  Have often had to start car and use wipers and washers to shift leaves, fine sand (blown off sea)  or bird poo. And of course in our lovely Scottish winters , to shift snow after starting and before driving off .  It's a Yeti 1.2 TSi Outdoor SE .  I'll post final garage outcome. Suspect there's a link to the bonnet position sensor but we'll see.

Just so I understand correctly...

 

You're saying it's just the wash/wipe that's not working when stationary?

 

Pulling the wiper stalk will only activate the washer jets (and wipers) to clean the windscreen when you're moving?

When stationary , with engine on and running , the front windscreen wipers will not work on any setting , irrespective of choosing any fixed speed or variable speed setting, or one flick even.   They're not auto wipers on this model. Also when not moving but engine running, front washers won't operate. 

But , the rear works .   

When you move off front wipers and jets work.  

Sounds related to what some suggest , a bonnet sensor or sorts.   

Had car years , thus is new.  It's now booked in, and I'll post resolution due course 

On my 2015 Yeti the wipers work when at a standstill with or without the engine running.

Yeah , that's what I did have , but it's gone . I'll post final resolution .

The bonnet latch has a micro switch built in. some have a mechanical switch that can get gummed up with grease/grime on some other car forums (including Mercedes) there has been success by cleaning them.

You could do a test by disconnecting the elec connector plug from the loom and link across the terminals to mimic the bonnet is closed to see if the switch is at fault.

NOTE! 

If you do this you must close the bonnet before operating the wipers!!!!!!!!!!

Thanks !  I'll give it a go . And let you know

Mine is a 2013 Elegance so pre facelift and wipers and wash/wipe work when stationary and engine off.

I don't suppose you've had a scan done with VCDS?

Are the wipers going into the Service Position, that is ignition off and flick the wiper stalk.   They should go to the vertical for winter or changing blades. 

The Answer :. Indeed the sensor at the bonnet catch had failed .  Replaced today , all working as normal . Washing and wiping to my heart's content, whether stationery or moving . Strikes me as a totally pointless sensor , driving 48;years and never had a bonnet fly up or elude the catch   Thanks to all that responded

Never had a Mk2 Phase1 or 2 Renault Clio then?

But someone may try the wipers with bonnet up and that could lead to damage to bonnet and wipers

Did you not have a bonnet open warning on the Maxidot?

No .
