The automatic window adjustment of 1/8th of an inch, when closing and opening the doors, is a big problem if the outside temperature drops to below freezing.
Do I ask the dealer to remove that function from the computer for the winter months?
For now i will leave the doors almost closed so the window doesn't try to rise the last 1/8th of an inch.
Temp solutions are cabin heaters overnight or spraying the window sill with airplane deice before opening the door.
This is the first time I regret the convertible over the hardtop.

 

The auto drop function is on both coupe and convertible. It is to allow the door glass to clear the top sealing rubber when opening and closing and not something like door mirror reverse dip that can be owner specified or enabled/disabled. If the glass didn't drop, you could pull hard on the door to force it past the seal but it would soon wreck the seal if this procedure was adoped other than in an emergency.

I know temperatures here get nowhere near as extreme as you experience but I use my XK all year round and often in sub zero temperatures. The auto drop is sometimes an issue fairly easily resolved with de-icer but a more regular one is freezing door locks at sub zero temperatures. That can be a considerably greater challenge.

How about ceramic coating the window? or at least the top of it??
When at a car race one of the inspectors was concerned @ a sticker blowing off of the glass because it had a ceramic coating applied.

Or just leave the window down just enough to barely contact the rubber seal...? Car will lock normally.

 

I don't understand.... I don't have a problem with my stuff in zero-F (neg-18C) weather. What's the problem exactly?

 

The difference between Utah and Eastern Canada is humidity. We normally have a lot of humidity and when it freezes it puts a lock hold on the windows. Enough to have the track break loose of the widow when it moves down and the glass stays in place. The same thing happens to the wiper blades, if you leave have left them part way on the windshield (wind screen) overnight and then press the start button.
I think Tracee solved my problem.

 

I grew up in Northern Minnesota so yeah, I know cold and wet down to negative 55 fahrenheit ambient. I don't specifically remember any problems way back then, but I remember my dad used to put vaseline on the door and window seals when it started getting that cold.

 

Oh…. I wasn’t understanding the issue. Perhaps if covered in freezing rain… but just frost!? We get -40 on occasion here andI never had an issue. Mind you, she mostly sits in a garage overnight, unless I take her up to Tremblant.

 

Treat the rubber on the doors. Don't leave 'em cracked, you could get snow in there.

 

Another good idea, to put some Vaseline in the upper rubbers, but the bottom slotted rubber will still freeze up somewhat.

 

Yes, treat the rubber seal with a lubricant to allow the glass to slide down…and make sure that your battery is kept fully charged.

 

Tried the Vaseline but the rubber changes to a non slippery surface because a petro chemical does eat at the surface.
So I will now use a transmission fluid, to avoid the conflict..

 

PS. By the way when the wx is close to freezing, my rear window heater is turned on automatically. Its a bit of a pain.
Is there a turn off feature, under the "vehicle" setting?

 

If no one is going to use ceramic on the glass then use this great wurth product for the seals

Maybe a thin coat of silicone on the seal; should be inert to rubber. Smells neutral, rather unlike tranny fluid.

 

okay, I'll make it more clear!
This is a caption from the above product, it was created to handle ice etc amongst other things...

"Product description

Preserve rubber gaskets and weatherstripping with an easy-to-use stick.

If you live in a cold climate, you've probably experienced frozen door seals. You try to open the door to your vehicle and it won't budge. Meanwhile it's freezing outside and you've got places to go. Now you can prevent the freezing of your door seals and keep the rubber healthy with SONAX Rubber Protectant."

SONAX is quite good, made in Germany, on Amazon and usually those applicators break off before the end of the bottle.
Just below freezing tonight so I put on some Mercon 3 Dex ATF with a brush . It went on well. The Jag has double the weather seals than most cars. Seal on seal!
I noted my Greek mechanic used ATF fluid in his pump oil can for years. Why not? If you have a suspected squeek in a rubber bushing, squirt it!
