Windows in car condensed on inside

[tucpal]

Most likely having the blowers set to up or windscreen only when driving
and altering the heater controls from warm to cold to warm
as having in just the up position actually turns the aircon on by stelf
this is to help clear the front windscreen
you can also have the same problem having the windscreen demist on to long
again this turns the aircon by stelf on as the heater warms up the condensation on the heater matrix
avaperats and mists the windows up
cure only have forward and up on to demist or when driving
this turns the aircon by stelf off problem solved

but also check for any damp in the passenger footwell or rear boot.

hope that helps
