Tested motor and linkage whilst on bench. No fault found. Lubricated everything including that cable prior to re-installing in car. I needed to re-seal the air intake cover but main dealer stated that the Volvo butyl sticky stuff was NLA but I think that I may have been fobbed off. I sourced and ordered some butyl tape on eBay but it’s not as sticky as the Volvo stuff although I think that it will do the job. Installed motor and linkage and tested it - OK. Refitted scuttle panel, difficult single handed, but got there. Light fading and rain starting so didn’t secure it and stopped for the night. Realised overnight that I had forgotten to refasten the cable tie on the motor wiring harness so next day removed scuttle panel again to do that then replaced and secured the scuttle panel. Tested motor etc. again - OK. Refitted NS wiper and tested with it lifted off screen - OK. Refitted OS wiper and tested with it lifted off screen - damn, something squeaking near the motor. Removed OS arm - no squeak. Replace it - squeak returned. Not of mind to remove the scuttle panel again so removed both wiper arms and the rubber spindle escutcheons and sprayed liberal amounts of “three in one.” PTFE lubricant onto linkage and anything else in the plenum chamber through the wiper boss holes and through the air grille mesh, with wiper linkage running. Squeak eventually faded then ceased. Everything now refitted and awaiting replacement wiper switch but car is useable again until then, unless the switch fails completely.
