My car has failed it's MOT due to the headlamp washers not working so need to sort it asap. They used to work fine, I've checked the fuse n it's ok, you can hear the second pump come on but nothing happens. I've just taken the bumper off to check for splits but can't see any leaks, I've taken a pipe off and water flows out but doesn't increase when the second pump comes on. I've had a search and read a few threads but no one appears to have had the same issue as me, so if anyone has any insight, I'd appreciate it.
