Intermittent Wiper Prob. on Citroen Relay

[CampervanDaddy]

Hi Folks

I'm new to the forum with a wiper motor issue.

I have a 2012 Citroen Relay that has an intermittent wiper problem. The wipers work fine in normal/fast speed operation as long as they haven't been on intermittent or wash/wipe mode, where they sometimes then 'stick' in the off position and won't then work in any mode for a period of time. Obviously a bit of a dangerous situation on a motorway in a thunderstorm. My wife recently had them on for 4 hours solid (with no problems), during showery weather, just in case!

I've taken it to a Citroen dealer, hoping it's just a replacement relay but apparently they don't have relays and it's a case of replacing the whole wiper motor at a cost of £422+.

I want to get it fixed before going to France at the end of the month but don't really want to spend that sort of money buying a new motor if it could potentially be another issue or solved in another way.
I presume also there are cheaper compatible wiper motors out there - any recommendations of manufacturers / websites to buy from?

Many thanks in advance...

Normally, the wiper motors are only capable of three things:
- off/park
- run normal speed
- run fast speed

Intermittent operation (and wash-wipe) is usually controlled by a timer-relay, which is easily and cheaply replaceable.
Will be very surprised if you need a new motor!

Hopefully, someone here can look at the circuit diagram for you to confirm.

Wiper stalk/switch fault is another possibility.

It could be like the C5/308 etc wipers which have a separate motor on each spindle with electronics keeping them in sync and controlling everything else (and I don't know if this is the case on a Relay). We need a circuit diagram, or parts diagram from servicebox.

Have a look at this thread, which was the result of water ingress - a clean up and re-seal solved the issue:

Thanks for the responses folks.
I will look into the possible water ingress scenario. I've also just Googled up Servicebox (presumably the Peugeot site?) as yes, it would be good to get a proper circuit diagram to see if there is a relay that could be at fault. Unfortunately doesn't look like I can join the site as a non professional. Anyone able to view this for me please?
If I do need to get a motor is this the one do you think?: http://www.ebay.co.uk/itm/For-Citroen-R ... Swcj5ZXNEJ.
Nearly 10x's cheaper than what Citroen Dealership quoted me!

You'll need to post up (or PM) your VIN and your RPO number for me - I can't do anything without this.

Be aware that the item in the Ebay listing is an aftermarket item and not original. The quality of these can be variable to say the least. I think that I might prefer a good (warranted for a certain number of months if possible) second-hand one.

You have the conrod assembly unit as above - item 1 is the motor, part number: 6405 PQ

Here's one for £113:

The only other thing I could think of is the Comms Module (under the steering wheel that houses the wiper and indicator / light stalks. It is a possibility that the circuit in the stalk might be worn for the intermittent setting - but hard to say without a physical examination I'm afraid.

Many thanks for that Marc. Been away in van for a few days and same prob. Will try a clean and if persists will get new motor. Cheers.

Ok Ian, so the part in the following link:
http://www.ebay.co.uk/itm/Front-Wiper-M ... xyOMdS-ofS

is stated here that it equals part 6405 PQ - which is the correct part number for your vehicle according to your VIN: (Click pic to zoom).

This contains the con rod assembly and the wiper motor.
