Targa leak

[martynljones]

Hi Guys,

My 02 Targa is misting up badly in this great British winter we are having. I know this is caused by water getting into the cabin somewhere, but do you think I can find any wet patches - not a chance! Has anyone got any ideas where to look apart from the obvious floor and bottom of the door cards?

Thanks in advance......

One trick I have used is cold a/c air on the windscreen. I'm not sure if it is all your windows but the a/c normally clears the windscreen good unless it has gone to a too thick of a moisture already. What might be happening is your car is exposed to winds so the windows are cooler than the surrounding air due to wind chill. Then pumping the always moist air onto the cooler surface causes condensation. It will even happen on the exterior windows at times. You could also have a heater core leak. I'd thing you'ld slowly see a lowering of radiator level if so. My personal favorite is the a/c till the heat level is up then I can blast some heat on the windscreen. Any slightly warmer air on the windscreen only causes condensation since it isn't hot enough to start to keep the surface dry. But colder air wont cause condensation since it is colder and the air flow evaporates and moisture forming the screen. It's a flip back and forth in temperatures some times but you'll always win the battle in the end :)

Yes it gets cold in Hawaii. It was freezing in the 50's and 60's lsst winter :D

Mine too!

I thought it might just have been because I'd been doing some maintenance and inside jobs in the rain causing the carpets to get a little moist. However last weekend it was beautifully sunny and both days I was driving with the roof open for an hour followed by an hour on the drive with the heater on full blast and doors, windows and roof open to dry out any moisture. I then drove this morning for another hour on the motorway with the roof open, the car was parked for a couple of hours and looked like someone had painted the windows white.

Sorry that I have no answers but I'm going to keep looking and I'll let you know. No obvious leaks - I suspect a/c.

I did have a TVR once and that leaked so badly that winter was a blessing - in winter you could remove the 3x8x12 inch slab of ice from behind the seats in one lump!
