Heavy Condensation

[johnnywas]

go to www.frost.co.uk and look up a product called air dry,it helps to keep the inside of the car dry .

Make sure the air is set to come from outside and not recirculating inside. That causes bad condensation if left like it too long as well.

 

I was keeping the air set on recirculating and was a nightmare, now it's set on the outside bit and most time it's ok even without the air-con on

That air dry stuff looks good.

With recirc on , as other have said, condensation will be a problem. I wouldn't go with the line that you need air con on all the time though . Unless you've got a source of damp inside the car eg sports kit or wet coat then it shouldn't be needed apart from for a quick front screen clear on a cold morning.

a source of damp like your warm moist breath hitting a cold window and condensing
