Late Mk2 wiper sweep issue

[BioDiesel]

Hi all,

Newbie first post - I hope you can assist with my problem:

I have a 2005 Mk2 2.3 zetec with annoying wipers.

The annoyance is the same symptoms as suffered by Fraz-ktf late last year....

https://www.fordmpv.com/smf2/ford-galaxy/driver's-wiper-not-full-sweep-stripped-lubed-but-still-the-same-!/msg5249/?topicseen#msg5249

...i.e. the wipers seem not to sweep the windscreen fully.

I have done the following to try and remedy the situation [with no success] :
1.  Removed and greased the spindles - they were not stiff at all
2.  Re-positioned wipers and drive - no change
3.  Pulling the arm when wipers on to make it sweep further - no slack in system - no change.

What did produce a change in sweep angle is switching off the ignition when the wipers are on and moving towards the vertical position - this made the wipers go further [whilst stopping] and sweep the window correctly.

This makes me think the problem is either electrical or brain related.

Question - are the wipers supposed to move from the 'park' position horizontally parallel at the bottom of the windscreen to a slightly higher 'wipe start' position, then wipe the screen only returning to the 'park' position after the wipers have been turned off ?  Mine don't do the park jiggle...

Does anyone have an electrical schematic of the wiper system ?

FYI - I have the factory 'aero' type wipers with the passenger side on top of the drivers when 'parked'.


Thanks for you attention

Cheers

Graeme

Ref. Fraz-ktf's original post where he said it was only the driver's side wiper that was falling short, on stripping my wiper linkage I found that there is an eccentric ball stud on the driver's side spindle ONLY which when altered will affect the maximum travel of the driver's wiper arm- see the last post in this thread. Of course, if both of your wipers are falling short this is unlikely to be the cause, so disregard this post!

[BioDiesel]

Thanks for the reply - I didn't know about the offset ball, however, as you suspect, this will only affect the driver's side and not both.

I really want to see a late Mk2 with the wipers operating to see if/how far the 'park' to lower running position distance is.

Really could do with the electrical diagram - tried loading the Ford etis but I don't have enough memory [nor has my computer].

FYI  I tried to view the library entry "Ford Galaxy - Additional information for windscreen wiper system (MK2)" - only to be greeted with the following error message "The topic or board you are looking for appears to be either missing or off limits to you."

I can view other library entries without issue.

Will look into it - thanks for the HU

Complete.
That was the link in the reference library index post yeah? It was pointing to a topic that's since been merged to the bottom of this one >Ford Galaxy - Windscreen wipers not working or slow < to help keep all info grouped together.

Again, thanks for noting it!

Hi Mark,

Thanks for the prompt reply - the setup information is really useful - i'll give it a go and see if it makes the difference.

Do your wipers park parallel and, when you operate the wipers move up  the screen a little and then the wipers operate sweep the screen not only returning to the park position after the wipers turned off ?

Thanks in advance

Graeme

[Mirez]

Yup, just like that - to be fair thats a VW trend, they only really park when switched off else they are in a ready state.

I can get you a schematic of the wiper mech as an assembly but not the internal electrics of it...

[BioDiesel]

Thanks for the reply Mark.  I would really appreciate an electrical schematic of the wiper system.

Thank you very much for posting this Mark.
It looks like the park/wipe position logic is all carried out within the motor assembly, however there is one possible lead - do you know what function the conductor 413-01-00-6 into pin 6 of the wiper motor has ?

[Mirez]

Yes, that'll be inbound from the instrument cluster and supplying a VSS signal. The wiper mech should drop one "level" when the vehicle comes to a stop. IE, if its on normal wipe it should drop to intermittent, If its on fast wipe it should drop to normal wipe before resuming when the vehicle starts moving again.

[BioDiesel]

OK - thanks for that.  It looks like the problem is inside the motor, I expect it's going to be water ingress and circuit board damage.
I'll pull it out and have a look.
Can you buy spare circuit boards ?

[insanitybeard]

Replacement circuit boards are certainly not available from Ford and I very much doubt VW either, it'll be a complete motor which I've heard it said are stupidly priced so it's gonna be a scrapyard job I'm afraid unless you can strip the old unit and repair it. There's always a few on ebay at more sensible money, though you'd have to make sure the part numbers match.

That's what I thought would be the case - I am going to strip down mine when the weather is a bit nicer and see what's up.

Thank you all for your support - I will report on progress.

Don't forget to take some piccys as this helps explain the problem.
