Is there a DIY to flush the wiper fluid reservoir ? Mine keeps clogging with the win shield pump but works fine with the headlight washer. I use the same fluid for both my cars and my girlfriends but I only have a problem with my BMW. If I blow into the hose it will work for a while so that is how I know there is a blockage. I bought the strainers to replace both but I wanted to flush out the tank. I found the DIY to change the pump and the filter. It looks like I end up disconnecting the fill hose. Can I just take a hose and flush it that way?

Thanks
