Condensation and mould inside the car

[Lee Riley]

Hello 

I have an old and beloved Lexus RX400h. On cold mornings there is a lot of condensation inside the car and now there is mould developing too. I have tried to source any leaks from window / door / sunroof seals but cant find any. I just gave the car a good going over with the pressure washer in the hope of forcing the issue but I can see nothing. 

However I noticed the rear inner door seals are worn and torn. Also the boot inner seal is damaged. There's no water ingress when I use the pressure washer but I was wondering maybe cold / damp winter air is getting inside the car causing the moisture. 

Any help to fault find is appreciated. Also and suppliers of the inner door seal or way to fix.

cheers!

PS the two front inner seals are ok
