This is to cut down solar UV rays - but does affect GPS reception. I stick my sat-nav on the driver's side window where it works much better.
According to the 1007 handbook, there is a non-reflective zone located above the base of the rear view mirror - this is intended for toll cards and/or car park tickets which need to be externally scanned.
A GPS device will work in this area as do my dash cams. The cable will tuck neatly under the headlining . . . .
Front blades are 24" and 18"; the Rear wiper has a special 12" blade
I use the Aero single-blade type which seem to last well and wipe well and quietly.
For cleaning the windscreen of all oily deposits I use Cerium Oxide either applied by hand or by rotary sander (careful, use a sponge pad!) if really bad.
Dolce models: have an intermittent wipe
Sport Models: have a variable wipe according to rain intensity.
Some variable wipe controls don't always work as desired as they age. They work by shining UV light at the screen and measuring the reflection. Try cleaning the top centre of the screen area to improve operation. It is also possible to remove the sensor unit from the windscreen to clean it BUT be extremely careful as I understand the clips make it difficult to remove/replace both the cover and the sensor unit.
It is possible to turn this automatic mode off using PP2000: plough through the menus and sub-menus:
The Rear wiper has a special 12" blade
If the rear-wipers start to get a life of their own, this can be caused by the COM2000 unit . This is the unit just below the steering wheel that holds the stalks and is known to develop bad contacts. When they do, the headlights and the rear-wipers start to enable/disable on their own. It may need to be accessed and the contacts cleaned, especially if the interior has been subject to a very high humidity.
Windscreen Washer Jets are unusual in that they are NON-ADJUSTABLE - also that there is no conventional jet to poke out with a piece of wire.
The part no is Peugeot 6438N4 The pressure of the windscreen fluid causes a fan-shaped spray due to the shape of the nozzle.
I cleaned them (they didn't need it) but both still squirted towards the bottom of the screen. Quick cheap cure: insert a flat-blade screwdriver and lever up slightly for desired spray shape and aim.
Close inspection shows that the nozzles, although separate items, are accurately glued in position. This is all very well as long as there is no distortion of the supporting framework.
The grille is still held by five hidden clips. Pull-up (some force needed) and free from bonnet, taking care that one end will still be limited by the washer hose. The clips are quite fragile and they WILL break so get some in before doing this job!
The jets are simply clipped in to the grille, just press the catch on the side of each jet; pull the old jets out of the hose and replace with the new ones. Replace the grille with 5 new clips and 4 screws and check spray pattern.
New jets spray water enthusiastically on the windscreen although one of mine still sprayed the bottom of the screen. Quick cheap cure: insert a flat-blade screwdriver and lever up slightly for desired spray shape and aim.
On mine I found the filter was blocked. It was necessary to take the pump out to get at it though.
From memory - if you need to take the pump out: Jack and remove the offside front wheel; remove the Splashguard which is held in place by eight plastic push-pin rivets and one 10mm bolt at the front skirt.
Then you can get at the pump - undo the connector and pull it out of the large rubber grommet. If you didn't drain the reservoir first you will now have screen wash all over your arm.
Dry your arm and clean out the filter
