Each morning I drive about 30 miles on the interstate to get to work. I leave home pretty much the same time each day (about 5:00 am). When I drive my 2008 XK, there are a couple of areas I drive through that cause my windows to immediately and totally fog up.

Of course I immediately push the button that fires up all the defoggers/defrosters. This actually worsens the condition for about 10-15 seconds until the windows begin to clear. It then takes about a minute for the windows to totally clear-up. During this time, I am literally “driving blind” at interstate speeds, as if a gray blanket has been suddenly dropped over my windshield.

Here’s the really weird part. This problem has never happened in either of my other two vehicles. In fact, in the last 10 years I have driven 10-12 different vehicles down this same stretch of road at the same time of day and the windows on those vehicles have never fogged up like this, not on ANY other vehicle I have ever owned.

All in all, this is pretty scary stuff. As I said it’s as if a gray blanket has suddenly flown up against my windshield at 70 mph…

Anyone have any ideas?

 

Why don't you fire up the defrosters when you first start the car to clear out any moisture that has collected on the coils in the dash. Perhaps when you get to the area later in your trip you won't have to deal with the worsening part.

You may be pulling in some of the moisture from the outside before actually getting the recycled/dry air produced from the defrost action...

 

Good point, I'll try firing the defrosters up first. I do still wonder though why I have not had this issue with other cars I own and have owned in the past...

 

It is the curse of the Big Cat!!!

As I keep reading this forum, seemingly most everyone eventually report some really strange problems that you normally will not find on any other make or brand. Must be the ghost of the old Jaguar.

I'm still hunted by the 2000 RPM exhaust drone that noone else seem to report but, it absolutely drives me up the wall. If it was not that, I would be superbly happy with the car. I actually considered driving with a set of earplugs in my ear :-). Imagine that, in a near 90K car....

Best of luck,

...and my XK, although it growls loudly when I stomp on the gas (I like that part), is actually quite silent while cruising at highway speeds. All I notice is the mellow purr of a satisified feline...

These sure are interesting cars...

 

My advice: Move to Seattle and leave the defrosters on all year round! It works for me.

There is a smog detector on my X350, probably one on yours, and its sensitivity can be set. It works by shutting the fresh air vent, and putting car into re-circulation mode. Of course this is one thing that can cause misting up !!

 

Check and make sure the water us draining out of the hvac box properly. There may be a build up of moisture in the box and when you turn on the defroster it shoots the moisture out the vents. Easiest to check on a hot day, turn on the air conditioning and check for the water puddle under the center of the car.
