peugeot boxer wiper relay/wiper issues

Afternoon all, having passed her MOT this year on the way back my girl developed a very strange fault, in the OFF position the wipers are making a du du du du du du du noise, in the 1st on position its the same and in the two fastest positions they move but a lot slower than they should. searched on-line for possible causes and one seems to be the relay? now i know where they are but I wondered if anyone knows which one it is?? I have 3 in a horizontal row and then 4 in a block to the right of them. I have tried removing each one and turning ignition on but its still doing the same thing so I'm really confused as i would assume (perhaps incorrectly) that if there is no relay there should be no power?? I would rather try a new relay than trying a new motor as there's obviously a major cost difference :-S, have also tried a bit of wd40 on all the joints on linkage just in case that was slowing it down. 

any help or advice appreciated as always

The first thing I would suspect is the self-parking mechanism, because this should be receiving power irrespective of the switch position. Unfortunately I don't know how self-parking works on a Peugeot, but knowing them it's probably not how everyone else does it (with a switch on the motor body). Hopefully a Boxer expert will be along soon...

its certainly plausible as they not going into correct "park" position, in all fairness the selector stalk has always been a little iffy switching between speeds and intermittent never seemed to select but they always switched off and parked themselves. did try to remove stalk to see if anything causing a short that would keep power to it but haven't got the right sized socket to get steering wheel off anyways :-(

I'd suspect the motor brushes and parking mechanism

I can guarantee the bushes are but is the parking mechanism actually inside the wiper motor frank? i found a new one on ebay for bout 35 quid but figured as relays cheaper i would try that first but knowing which one to change is the * Inappropriate Word * lol

omg really? b**g*r is an inappropriate word?? well whats the world coming to

Brushes not bushes

Never taken a Boxer one to bits but it's usual to have the parking switch inside the motor.

sorry yes brushes (clearly got autumn garden tidy on me mind) tempted to have a go at dismantling the housing see whats what, only thing putting me off is i know someone on here broke the screws trying to get the scuttle out to replace the motor and drive arms and had to re drill etc, seems a faff if i can avoid that

When I fixed my skuttle drain I broke 4 of the 7 screws trying to get them out - had rusted solid and Wd40 didn't help.
Ended up ordering a new set of screws online and drilling them out too - what a pain to do

it may of been your post I saw Richard

I took my scuttle off a couple of weeks ago with no problems. Well only one really.......I couldn't get the Allen key in a couple of the heads of the bolts until the rust had been scraped away.
Used 'copperslip' on the threads when refitting.

morning all, I have a 1998 Talisman, and the ist wiper speed (intermittent does not work) .Is this the relay playing up and if so where is it to be found ,Thank you Lew Barlow Wolverhampton.

I had this problem last year (boxer symphony 2.5D) . No intermittent wipers, no self park and no fast speed. I took the motor out , stripped it and cleaned the contacts.
I got it working fine for a few weeks then the intermittent wipers failed again so i bought a new one from eBay.
I managed to change mine without removing the scuttle cover, a bit awkward but can be done. Might be different for other models/ engines.

Hi - scuttle doesn't need to come off to get to the motor housing - which houses the intermittent switch. It can be reached from underneath the centre of the scuttle - cover is held on by 4 plastic clips. Tricky - and mine is now held on with three having snapped one off (still works). The rotary mechanism that forms the intermittent switch on/off does get caked in the grease in the housing which was causing me problems. Cleaning this up fixed the wipers.
Like others - when I removed the scuttle to fix the engine bay leak, sheared all but three of the bolts. Drilled these out and tapped for new bolts. Slow and difficult to get straight, but worked with patience. If you need to drill out such hard metal I can recommend the bits from Screwfix - Erbauer HSS trade pack - 150 various size for about £20. Just slowly with light pressure.
