A big thank you to Mumof4/Maz for starting this thread and to all that helped with this problem. The wipers on my 53 plate galaxy decided to stop working and with the help of this tread I stripped it all out, cleaned, hammered, heated and greased before re-fitting, all working great, took about 2 hrs, I stripped the attery out and the plastic divered that the expansion tank bolts to, made life easier for me. Then as i had all the tools out, i then tackled our 1999 Golf Gti which had developed the same problem another 2hrs and all working. Thanks again to everyone Eifion
