I've just had the bumper off and fitted new headlamp washers and hoses.
When the lights are on and I activate the washers, screen washers work fine, headlamp washer motor activates for about a second then off then on for another second. Nothing comes out though!! I'm assuming its because there needs to be pressure in those hoses and maybe theres a function to put it in to 'test mode' or something to get the motor to run for longer to fill the pipes.
Any ideas anyone?
