wiper mechanism

[sawood12]

Just realised you can't remove the wiper mechanism with the fan unit in situ anyway so looks like i'm going to have to do the job with the mechanism in place. Anyone know what the best substance is to remove old gunky sealant-like glue? The top of the scuttle panel is glued on so i've got to remove all the old glue and clean up the surface before I can bond on the new scuttle.

Strangely enough I did this the other day, I had managed to get hold of a used wiper motor (mine doesnt work on intermittent or slow speed wipe) and wanted to test it before dismantling the wiper mechanism to fit it. As the 'new' motor came with the plug on the end I simply wanted to connect it to the block and see what happened. After much wiggling and gentle prising with a screwdriver I manged to remove the complete block from the metal bracket it sits on, trouble is the damn thing wont go back on ! Oh, and the new motor worked fine Unless someone comes along with a better method I guess gentle perseverence is the key []r

Thanks for that. So did you have to remove the wiper mechanism to fit the wiper motor or did you manage to replace the motor with the mechanism bolted in situ? I don't need to replace my motor, but can't see how I can remove the mechanism with the fan unit in situ - and i don't really want to go down the route of removing that as well. Cheers.

Scott I haven't had time to replace the motor yet but I believe its a wiper mechanism out job , I may have a go at the weekend providing SWMBO doesn't have any 'other' plans. Howard

Decided to open my toolbox and install the new plastic scuttle I bought last year and the dog-bone wiper linkage. Once I removed the old broken scuttle and saw that the stuff under it could do with a good clean out of old dead leaves and things I decided to remove the wiper mechanism to give me more room. Removal is easy, but I cannot suss out for the life of me how to disconnect the wiper motor connector from its block! Seems like it wants to slide off as there is some slight movement and a sort of tang tab on the top that looks like you need to bend it back with a screwdriver, but the thing wont shift. I don't want to force it in case I break it and you know it will be one of those difficult to replace items. So can anyone here who has removed the wiper mechanism advise how to remove the connector?

Thanks.

Hi Scott, Its not really as bad as it looks I had the fan unit out a couple of times on my 944S and apart from some scraped knuckles it comes out quite easily. There are six or eight self tapping screws that hold it on IIRC using a size 8 or 10 socket with a "wobble bar?" to get into the space beneath the windscreen. After removing it once it only took me about 10-20 minutes the second time. Then you will see that the wiper mechanism is held on in several places IIRC, I gave up trying to remove the motor from my old wiper assembly as the screws that held it to the frame must have been welded on ! I guess some heat and penetrating fluid would have freed it eventually. PS. Are you still running the VW Lupo GTi wiper arms ? Regards Dave K.

Thanks for that. I've not been running the Lupo arms for a while. It worked great in the drivers side location, but was very close to the windscreen on the passengers side location and sometimes the spring would just glance the windscreen surface making an annoying scraping sound. I've been on the look out for some similar wipers that stand off a bit. However they worked much better than the stock arms at speed. A good mod if I can find some modern arms that actually fit and provide enough clearance. You can't buy brand new arms from Porsche anymore, they're not manufactured anymore and Porsche don't have any stock left, so unfortunately if you need brand new arms you're looking second hand which means tired and weak springs, so identifying some modern alternatives would be useful. I might give the Lupo arms another go when I re-assemble and bend a kink into the arm on the passenger side one to try to provide more clearance between the windscreen and the wiper spring.

Without wishing to hijack the thread, did you have a good source for the Lupo arms other than a VW dealer? I'm going to replace my wipers soon so was going to go for either the Valeo flat blade type or the PIAA silicone ones... Dave

Just for info I replaced my standard blades with aero ones from here [link=http://www.autobulbsdirect.co.uk/]http://www.autobulbsdirect.co.uk/[/link] . Simply enter your car details and scroll down the choices until you find the aero wipers, they do a full set for £21 (2xfront and 1xrear) Huge improvement over standard wipers (in my view) and may overcome the tired springs issue.

Got the plastic cover and the heater box out fine, can see how the mechanism is fixed by the wiper mounts and below the wiper motor but stumped after that? All help appreciated and save me having to go back to my local indie for a 'told you so' moment![&:]

Theres another bolt into the bodywork under the windscreen somewhere, that should be the only thing holding it to the car once you have removed all the other gubbins. Dave

Excellent - found it so many thanks. I take it the fixing point is welded to the outer skin and not a bolt that will drop through behind when I take the nut off?! Round 2 of grazed knuckles tomorrow and then on to the sunroof gears...
