Hi, my 99 disco is only cold on the passenger side; It`s cool on the D/S but really struggles when we get hotter days which at the moment is alot of them.
I checked underneath and the passenger side is the only one dropping any condensation from the outlet; the drivers side isnt blocked as far as i can see from underneath.

Is this a common problem and whats the fix? I am going across the Nullabor in 2 weeks and it could be rather unpleasant.

Thanks, Mark.
