Hi rear wiper on my fabia 2 2008 1.4 d estate is not working, I’ve checked the fuses ok and there is 12 volts to the plug, 4 cables I believe black positive, brown negative, and a green and white and green and red cables. I removed the motor and bench tested it, the motor ran but I read the motor may have not parked. I purchased a wiper motor from eBay it didn’t make any difference still doesn’t work. I would appreciate any suggestions thanks in anticipation.

 

If there is power to the motor plug (meaning car wiring seems to be ok) and the motor bench tests OK, .....seems it might be the stalk / switch

 

Power is supplied down the balck wire, but is controlled by the switch wires, which is the red/green and green/white.

 

So what you need is to test if there is 12v supplied at the plug on the green / red wire when you operate the switch (need a friend or VERY long arms 😁

Yes I thought of that but when I push the stick forward the washer works fine, is there a relay somewhere I can check tomorrow? 

Thanks again for your input.

No relay, its supplied from the voltage control unit.

 

The power to the washer is supplied through the motor on that black wire then out on the green and white wire......as it does also for the boot release button.

 

There is also a 10pin connector in the boot on the left hand side, most likely behind the trim panel. The red green wire comes also through that, so you can check the stalk / switch at that point as well.

Thanks for that I’ll check that today and let you know how I get on, I’ll get my wife involved ( that will be fun ) it’s nice to talk to someone who is so knowledgeable I’ve struggled for over a week trying to sort this out , at the cost of a wiper motor. It seems other people have had similar problems. Thanks again for your valuable input.

Hi again here’s an update , black cable +  to brown - 12.4v black to green / red when switch is on 12.4 v when switched off 11.8 v  black to green / white 0 v now the worry black + to car earth - 8.4 v 🤯 any ideas greatly appreciated thanks.

Ok lets take these results one by one....

 

Black cable to brown cable 12.4v  -- this is good, this shows the earth path (brown cable) the motor uses is good.

Black cable to green/red 12.4v when switch is on  ---- this is also good, shows the switch is sending the signal to the motor

Black cable to green/ white   ---- will be 0v ---- but "should" be 12v when you use the washer (we know that works)

Black cable to car earth 8.4v --- where did you measure this from / to ?

 

Are these measurements @ the motor plug OR the 10pin plug I mentioned earlier ?

 

 

PS are you 100% sure your purchased motor is good ???

Thanks for replying so promptly, all the measurements was taken from the plug, first the Black cable + at the plug for the motor to earth was to a bolt that holds the tailgate on to the car body and the same reading was to the car body work scraped under the paint. What surprises me is there is no continuity between the brown cable and the car earth ie the bolt.  The car is an estate and the cable travels through the top of the roof. I bench tested the motor removed at the motor connection internally and it worked, but thought the problem may have been with the pc board. So I bought an other, that came with a broken bracket, they sent me a second one so all together I have three and none of them work. Any other suggestions are greatly appreciated, thanks.

@Gaga you do understand that the wiper motor will need a permanent 12V, 0V and get fed with a switched 12V to make it move away from the parked position - did you bench test the removed motor by connecting it that way?

 

Sometimes you need to be aware that if you unplug a socket and try reading back into that socket, you might get good results when in fact if you had done these checks with the socket connected to its normal load you would get different results, certainly that can happen when one or more of the wires are partially broken.

Also which fuse did you check ?

 

Hi thanks for all that, first I tested the socket to get the supply voltage from the black to brown then the green and red from the switch both gave me 12.4v the washer is working fine that’s what prompted me the buy another motor. I have tested all the fuses under the dashboard individually and they all test fine, the fuse I believe is for the wiper is a 10amp second from the left. I’ve just been out and double checked the readings. I’ve got between black to green and red 12.4 volts when switched on, but 11.8 when switched off. Is it reading through something? Am I missing something? Thanks for all your help it all seems rather confusing.

Surely if there is a supply voltage and a switched voltage to the motor and a reading of 12.4 v to the brown 

Help someone I’ve taken some more readings this morning can anyone make sense of these? Switch is On  Black to brown 12.4 v this is the strange one black to green and red 12.4 v is the green and red switching the negative because when the switch is Off it reads 11.7 v  the green and red to the car chassis is 0 ohms a closed circuit as it is to the brown. The 10amp fuse second from the left, has no voltage to it when I turn on the switch . Could the fault lie with the voltage control unit , your input will be very much appreciated thanks.

You need to check fuse 26 and fuse 40 to make sure they are good.

Thanks I’ve removed every fuse today and tested them all individually and they all tested okay 👌 should I have power to fuse 40 at any time? Cheers 

If you pull fuse 40, then the black wire at the motor connection "should" then be 0V

 

PS have you tried bench testing the motor using all the connections ?

 

The Skoda rear wiper motors were notoriously bad at failing in the early days, its a good chance that has happened.

Thanks I’ll try that tomorrow, what connections should I use to bench test with the battery from left to right  I assume #1 black +  #2 green/red ?  #3 green/white ?   #4  brown -  thanks again for all your help , much appreciated.

Well...attached is the wiring diagram.

 

The connector is T4c

So looking at diagram.....

 

Supply permanent 12v to Pin 4 (black)

Earth / ground Pin 1 (brown)

 

Then I would try by applying +12v to Pin 3 (red / green)

 

Hopefully that should operate it. The green / white wire Pin 2....... I think ONLY deals with the washer motor.

 

 

 

Good afternoon today’s update, I bench tested the motor as you suggested and nothing happened, but surprisingly when I reversed the positive and negative connections the motor ran , I’m now confused even more. I have contacted the supplier of the motor and they claimed to have tested it before dispatched. Any ideas thanks.

Did you reverse just black and brown ? or also the red /green ? did it continuously run ?

 

often a claim of breakers that they test stuff, how do they do that if a car is smashed up battery disconnected or removed etc etc............think of the time involved in testing all these parts..............think a lot of them just bull**** it to be honest.

 

There is ONLY one way to prove it, that is put in a 100% known working motor, that way it will then tell you if your car is the problem or not (I doubt it is your car) but could be wrong.

Thanks for you support on this it’s very much appreciated, I just reversed the black and brown and yes it did run continuously, I didn’t connect any other terminals, strangely enough it was on my original motor I removed. I have contacted the supplier of the other motor and he has arranged for collection today with a full refund of £38 , I bought it from eBay with 30 days warranty. I am reluctant to buy a new one in case the problem lies with the car. Interesting I just looked back on their feedback and 3 out of 5 negative scores was for motors bought and not working. Although I can buy a new one from China for £20. I’m now wondering if this is the correct motor for the car , it’s a 2008 mk2 and I believe that was a changed model the motor I have taken out looks new I just bought the car four months ago from a back street garage and I never tested the wiper until last week so I’ve never seen it working, would the terminals be the same on the previous model? Have they fitted the wrong motor. Once again thanks for all your help.

PS I’m thinking of going to our local salvage yard and try one on site , they have lots of VW and Audi the A3 looks similar.

I think that you should check the part numbers of the rear wiper motors on other models against your one, easier to do it online on a VAG parts listing website as while a lot of them look the same, they are - except the shaft will be differing lengths and that will be a show stopper - I know this as I got a repair kit for a 2002 VW Polo and used a guide as a part number source, on the Fabia MK1 section of this forum, it seemed like Fabia MK1 used same rear wiper motor as a VW Golf MK? - well it must of done but a similar aged VW Polo certainly didn't - my mistake, so I needed to buy a second kit!

 

Edit:- oh and planning on swopping over the drive shafts if this is what you find is not in my mind a good plan as the lower gasket will probably break up and the small O-ring seals will be hard so will not appreciate being removed and refitting.

Thanks for that I ordered the same motor Skoda Fabia 5J 07-10 Estate Rear Window Windscreen Wiper Motor 5J9955711 as I removed from the car it fitted perfectly and was like for like , but didn’t work as explained in my previous threads, that’s why I was wondering if it had been changed at the garage for a different one , how do I check it’s the right one for the car? Thanks for your input this is driving mad.😫
