Hi I have a 2019 Toyota GT86. I topped the windscreen washer fluid to the top of the funnel and the level has gone down (drained the entire tube) without using the wipers, however the reservoir still remains close to full. Is this normal? The garage said that it’s fine, however just wanted to double check this is a common issue. Can’t see any puddles under the car when left. TIA Sent from my iPhone using Tapatalk
