Peugeot 807 Blocked front Washer Jets - Access to Wiper Blades

My Peugeot 807 (diesel) front washer jets seem blocked as the rear screen
wash works OK but the front does not.

I want to try and unblock the holes with a pin but the wiper blades always
disappear out of reach behind the black guard at the bottom to their park
position and refuse stay at the top of the screen even of you turn off the
engine part way through the wipe cycle. The onboard computer just keeps
them going until they park fully.

How can you get access to the jets as the blades do not lift in their parked
position and the jets are on the arm and NOT the removable blade.

Thanks

Pull the relevant fuse?

Thanks Bob as I had missed the obvious solution. Shortly after I posted the
question I realised the battery box is in the driver's foot well so I can
pull the quick release battery clamp at the appropriate time. I shall try
this tomorrow in daylight.

Thanks

Hi,

It may well be like on my 206 : ignition off, give a move to the wipers
control. They move and stop at the top position.

HTH,

 

If the 807 has a BSI fitted I wouldn't go just pulling batt leads off as
you can corrupt the software in the BSI unit there is a way of doing it .

Hi,

I agree with that, however the procedure given in my 206's user's manual
(muxed model) is easier and not that different.
What is not said is having the key in the pocket, in case the car would
close by its own upon reconnection.

Quoted & translated from my manual (too lazy to look inside the UK manual) :
"After reconnecting the battery, put ignition on and wait 1 minute before
starting, in spite of initialize electronics. However, if some little
problems still occur after that, please contact a Pug service center".

Needless to say that a battery disconnection (the 3 minutes rule) and
reconnection should be the way to go at first.

Regards,

 

If it's anything like my 307, the user manual should tell you how to park
the wipers at the top position for blade changing. Definitely no need to
disconnect the battery or pull a fuse!

 

Scuse my ignorance but what is a BSI?!

I sorted out my original windscreen wiper problem before reading the rest of
this thread and am grateful for all comments. I had in fact pulled the
battery connection to stop the wipers at the top and I also changed the
battery (another issue altogether).

I knew nothing about the soft reboot procedure or the 3 minute rule.

I did however get an "engine immobiliser error" message (from both key fobs)
when trying to start my car after re-connecting the battery. I have have
never seen this message before when changing the battery. It seemed to
disappear after a couple of minutes and both key fobs seem to work OK now.
It worries me that a car that depends on software so much should be in
jeopardy by a simple task such as changing the battery which his something I
have done many times over the years. I will try and avoid buying such a
complicated car in the future.

Is the immobiliser error a common problem and what can be done to avoid it
in the future. If I ever had to change the battery in the key fob does
anyone know how you re-program the pair of key fobs to work with the car
again if anything goes wrong.

Graham
