Hi all ,thank you for your replies and helpful input .
The wind whipped up the drivers side wiper ,there was a clang ,then no wiper ,with the road works at Wisley , there was no hard shoulder to pull in ,luckily there wasn't a lot of traffic at the time coming off the slip road taking the A3 down and on to the M25 ,and as it was dark ,the rear lights of other drivers gave me a rough guide to were to be on the road ,when I pulled in at Cobham services ,I found the wiper hanging upside down below the windscreen ,so put it the right way up and tried the wipers ,the little spindle end and nut appeared to be turning ,but not the wiper ,so i thought the nut was loose ,got my spanner to tighten it, and snap ,off it came......
I then thought I could just change the passengers side over to the drivers side ,but it became apparent it was a more involved job than first thought , I was cold and wet ,wearing shorts and a t shirt lol , so waited for the rain to slow down a bit ,and drove back onto the M25 ,which was a nightmare ,the over head signs were flashing 50mph due to the amount of surface water ,but unfortunately most drivers ignored it and were flying past at 70 + it has to be said ,the lorry drivers were the worst ,and the amount of spray that was thrown up made driving bad enough for the drivers with 2 wipers !
I realized after a couple of miles I got about 3 inches of screen I could see through on the passengers side ,so it was an interesting half hour drive home to Edenbridge ,my dog thought I was leaning over for a kiss ,so spent most of that time licking my ear ,yuk LOL
I have bought a replacement spindle from just Kampers ,which comes with all the washers rubbers etc ,but saw on eBay last night someone selling the whole original wiper motor frame with spindles attached ,cheaper than the spindle I bought from JK so will probably wait on that arriving ,and just put that in and keep the rest as spares .
I have been working in beacon hill surrey and need to do a couple more weeks of work there but will wait until I have sorted the wipers out ,its forecast to be very wet again ,and don't fancy a repeat off last week ,for my sake and other road users !
i have just looked under the dash and the mechenisim is moving as should ,so hopefully when i go in to change the bits over all will go smoothly !
the chap I bought the part of on Ebay ,Swanseabaysveedub , suggested that if I take out the glove box inner and the air ducts in the top off the heater post ,I should be ok to get everything out without taking the whole dash off ,I will give it a go and report back when completed ,fingers crossed ! thank you all again ,Michael
