Title: Windows steaming up when I turn the heater on.
Post by: The_Gods_Must_Be_Crazy on July 27, 2007, 16:11:22: Hi,

The other day I was driving home in the rain without the heater on. I decided I wanted some heat so I turned the heat and the fan on. Almost instantly my windows steamed up, leaving me frantically wiping the inside on the windscreen so I could see where I was going!

This has happened to me once before, in similar circumstances, and I was wondering what might cause this - maybe water sitting by the heater waiting to be turned to steam when I turn the heat on, or if anyone here has had similar experiences and knows what to look for.

Cheers,

Dan.

Yep, that's it, I had the same but once unblocked no more mist :)

As previously stated either the matrix is leaking or the drain-bulb needs to be squeezed & emptied, amazing how many people don't even know about it.

I had the same... removed the blocked drain plug from under the heater intake... never bothered to refit it...

Likewise, except i had to remove the intake as well to clean it out as it was full of stagnant mud :roll:

will give have a look tonight. i take it you are all talking about the plastic intake underneath the passenger wing, with the grill on top? (i'm okay with older landies, but not so knowledgable with the newer stuff!)

Post by: Edge on July 30, 2007, 17:57:53: Plastic grille on wing feeds heater air intake (passenger side). Look for big black box in engine bay exactly infront of passenger...it has a cable on top that adjusts it from within cab!!! Underneath you will feel a rubber nipple type thing (has a slit in it to allow water to escape), pull it free (you can refit it no prob). Water will run out of the black box....."job done-no more steamy windows". (that is a 300tdi, not so sure about td5 etc)
