  • [Corsa D] Worried about possible windscreen wiper motor fault.

    I noticed this morning in light rain that there is an audible "grumble" when operating the front wipers in any of their modes i.e. fast, slow and intermittent. Its not a grinding, more muffled than that and it doesn't happen with the rear wiper. Its NOT the wiper blades which were fitted new just a month ago and clear the screen well.

    Am hopelessly non-technically minded but wondered if its a sign of a fault developing with the windscreen wiper MOTOR ? Checking online it seems that a GRINDING noise might be an indication but as I said, this is more a muffled grumble. It seems to be from immediately in front of me when in drivers seat.

    Does the rear wiper have a separate motor?

    If it is a new motor needed, are they expensive to fit?

    Appreciate any input.

    Meanwhile y'all have a good Christmas and a happy and healthy 2019.

    Hi The rear wiper motor is separate (although the washers share the same pump) Could it possibly have been due to frost? What happens if you lift the wiper arms so they are upright and away from the screen then switch the wipers on? I'd also carefully check each wiper blade to ensure it hasnt become slightly dislodged in some way. This might allow it to judder slightly as it wipes even though it wipes well enough. Did you fit good quality blades? Cheap ones are more likely to be damaged quite quickly, especially if you have tried detaching it from an icy screen. Again this might allow quite decent wiping but a slight split in the moulding of the blades might allow it to flex sideways too much and judder.

      Thanks for the response !

      The blades are Bosch and have worked fine for a month. There has been no ice on the car for a while and they don't judder at all visually. I will try lifting the blades off the screen and switching them on as you suggest. probably gonna have to book it in at Perry's here in Colne who are excellent.

      Merry Christmas !

          OK i Have a wiper motor for a Corsa that was sent to me by mistake, it has a number of ZR23000826 on the invoice,Came form PARTSHOP247,sent to me as a wiper for astra mk4,,but the wiring was to short ,told me to keep it ,and sent correct one onto me.if you look on the site you can check if the number is ok for your corsa.(mk 3 ) yours for the cost of the postage to send to you,
          MERRY CHRISTMAS. Roy

            I have recently fitted Bosch blades to my Yaris. These were of a universal type with a variety of adaptors to suit different wiper arm mountings. The yaris takes the most common type as already fitted,So I did not have to change adaptors. Even so I found the blade appeared to fit quite well ,but having once lost a blade on the motorway i persisted and found i needed to continue pushing it on quite hard until it finally clicked securely into place. This was not obvious visually.

            when i fitted universal Valeo branded blades to my corsa D a while ago I had to change the adaptor. With the wide variety of brands and adaptor types on the market its quite possible that even an expert fitter might fit the blade in a way that looks and even feels superficially secure, but is not fully clipped into place. It may work fine for a while. Its worth double checking.
            GM use their own unique type of blade mounting. You can buy the direct original type of fitment but universal blades are more readily available.

            Even a tiny thing can cause blades to make a noise. TBH when i replaced the blades on my Yaris I couldnt see anything wrong with the old ones, but the new ones were notably quieter. But sorry if you have already eliminated these possibilities. I have no way of knowing if your problems and noises go beyond this level.

              Hi DURGAMAN

              Sorry I'm a bit slow at responding to your very kind offer. I've only just spotted it !!

              I will call at my local Perry's soon after Christmas and if they say its a new motor needed I will quote ZR23000826 to them and if they say "fine" I will take you up on your offer. Will be back in touch either way.

              Many thanks again and Merry Christmas.

                Hi Bugman

                Thanks for taking the time to write at length.

                I fitted the blades without any problems and have done a couple of lengthy wet Mway trips with them. It really doesn't sound as though its a sound from the blades themselves. I saw a suggestion online to pull the wipers away from the glass and try them. If its a wiper/screen problem there should be no noise.

                We'll see !!!

                  Let us know how you get on.

                  Another thought that may not apply in your case but might help others. Its possible for the windcreen to become contaminated with something which may not be visible but affects the friction of the blade which may effect noise. It may also cause smearing. Things you may have caused yourself such as overspray from silicon spray, ,cockpit spray, tyre shines, back to black cleaners, even some shampoos or polishes. Or external contamination, eg by following a smokey vehicle,bonfire, tyre smoke, brake dust ,tree sap ,insect excretions etc etc. . . An indication of this is if things improve temporarily if your screen wash contains a soap/detergent ingredient.
                  . Normal car washing and wiping does not remove all contamination . I regularly clean my windscreen with a specialist glass cleaner. Its amazing how much more dirt comes off glass you though was perfectly clean I also wipe the rubber blades themselves with a tissue soaked in glass cleaner.

                  In fact As an experiment I have just gone out and wiped the Bosch blades I fitted less than a month ago. Some fairly mild household glass cleaner on kitchen roll removed a significant amount of black muck.

                    Further to the Corsa wiper motor I have, the number i have quoted is not a Vauxhall part number, it came from ( PARTSHOP247 and was about 23 which was less than half the price of the V/X ones ). so it may be of no help to quote this to Perrys, to add I think this was the number on the box ,was for the Astra wiper motor, but it was a Corsa motor that was in the box, .only diff: was the connecting wiring plug from the engine bay was to short to reach the motor connector block..,looking at Corsa wiper motors they all seem to be the same from from 2002 onwards to 2011? As BUGMAN says if the motor has been operated when the blade was frozen to the screen it strips the splines from the wiper blade holder where it pushes/bolts onto the motor spindle, with the resulting grinding sound as it rotates and chews away the splines that grip ,in the past I have mended this by a small wrapping of bacofoil on/ around the motor splindle/splines so it will grip into the wiper blade when it is screwed back down.
                    My best ever bodge was on a Nissan Cherry Europa (this had an Alfa Romeo flat four engine) throttle cable snapped in the lakes, managed to get some orange colour nylon string and threaded it thro the bulkhead and onto the throttle operating rod , and tied it on ,made a loop on the end that came thro the bulkhead and used that to operate the throttle with my hand by pulling/releasing it for changing gear etc, lasted the whole 5 days left till i got home, gave myself 10/10 for that one.
