Thread: Windscreen condensation

I recently read a thread on a UK forum about mods to the heater. One thing that was found to help a lot was fitting a hood over the cowling. Not only reduced the rain water ingress, thereby less screen misting, but the heater core became more effective at heating the air, because less heat was lost to water in the air.

The other thing that worked well was a recirculation duct from the passenger foot well, and a flap under the inlet cowling that could close off the fresh air.

Yeah they are called snow covers and designed to stop snow going in.

But I had one on my 90 to stop water pouring in when wading.

Correct, as usual

Thanks mate, I'll try it out tomorrow. So, yet another design fault with the Defender

Or lack of maintenance. Your 130 is pushing 20 years, stuff like this is going to need attention. I'm not trying to make excuses but a blocked drain in 20 years is not unusual but then again probably wouldn't go wrong on a Toyota.....

I'll compromise with both design fault and lack of maintenance. Admittedly, quite easy to unblock, but the fact even mechanics end up removing the offending rubber part says it all.

Methinks it's just the last straw in a few frustrating issues that's got me considering alternatives...
