Condensation inside

[W1ghty]

Cat litter filled socks (stop laughing at the back there) works , SWMBO did it with her ancient Zafira after transporting hay bales in the back . Got rid of the condensation (eventually) . Note the A/C on her car does not work properly. At one point I stood a small household dehumidifier in the car ...but it froze solid overnight

But there must be a better way .

The better way is to deal with the problem (if you can find it )
