graham_GB I would suggest checking the scuttle drains (that let water out from the area below the windscreen) first. If these are blocked, and/or that area is full of water, then this needs to be addressed first (and is 'A Good Thing' to do regularly anyway). Several previous posts about his, but here is a good start and has photos to help: https://www.fiatforum.com/panda-iii/475219-scuttle-drains-no-duckbills.html?p=4491914. If there was water here it will likely have got into the heater and soaked the filter.

As to the filter, this post will help. It omits mentioning how to start though. You need to remove the side panel of the centre console on the drivers side (that includes the left foot rest). This is done by unscrewing two large Allen screws from two deep-set holes by the footrest, and one smaller Torx screw a little further back. Once these are removed, the end of the panel nearest the front of the car can be pulled towards you and the rear part (nearer the handbrake) unclips an it all lifts away: https://www.fiatforum.com/panda-iii...n-filter-my-easy-way.html?481366=#post4543190
By the way, for information and amusement, have a read of this fairly old post form the 2005-2012 Panda forum, as that will explain why we keep referring to these drain points as duckbills https://www.fiatforum.com/panda/272828-loose-plastic-thing-full-water-3.html
