2008 XKR Coupe.

If it freezes over night I ALWAYS have issues. I'm in Seattle, we're talking a light frost and 30 degrees F, nothing crazy.

It's as if the car loses power to the doors. The door will unlock, but the windows won't roll down, even the little bit needed to clear the seal. The side mirrors also wont extend. The glass isn't frozen to the seals, I can push on it and it's free. If I get in the car and start it, still nothing. Windows and mirrors won't budge using the controls inside. They don't even sound like they are trying to move.

If I let the car warm up (enough to defrost the windshield), then turn it off and back on again both mirrors / windows will usually start working again. May take more than one cycle. I've never had a problem above freezing temps.

What the heck? Is there a door control module or something that's susceptible to freezing temps?

 

Battery Low??????
May sound wrong, but for nearly everything, Check the Battery!
You should have 12.6 volts after sitting for awhile.

 

hmm. I’ll start putting it on the CTEK while outside

 

Very common problem across the full JLR range . Fix is to replace door lock module

 

Winter temperatures can cause car doors to be difficult to open, but replacing a door lock module is bad advice.

This problem has been previously asked and answered, and the door module was not mentioned as the cause of the problem. Cold winter temperatures can cause moisture on the weatherstripping to freeze, which prevents the door from opening. Other causes include misalignment and improper lubrication. Replacing that module should be the last resort.

And this 2017 thread:

My Advanced Search of the X150 Forum revealed that there are no threads where the solution to the problem of a frozen door was to replace a door lock module.

 

It is far more likely to be a low battery (yes, the car will start normally...); the various modules on these csrs need full battery voltage. When they do not get it, odd behaviours (exactly like this) are the result. The "supporting documentation" is that after the engine has been running for a short while, sufficient voltage is being provided to the modules in question.
For any, any, odd behaviour in the electronics (it can be anything: touch screen, door locks, windows, warning lights, top not latching....) the very first suspect is the battery. If your battery is over 4 years old, that is your first thing to check/replace. And new batteries are almost never fully charged at purchase so your CTEK unit can take up to 36 hours to bring it to full charge (I speak from experience with a 2007 XK battery replacement. The first sign of failure was tire pressure warning lights...fully charged new battery: the lights disappeared permanently).

My XK is always kept on a CTEK overnight and the battery was replaced three months ago.

We had one night at -11 followed by another at -2 deg C last week. Both times my windows were solid in the morning. In low temperatures I turn off the powerfold function for the exterior mirrors to avoid mechanical damage.

If you are a zealous car washer, your door handles can also freeze.

Consensus on cold weather......
IT SUCKS!

 

Exactly! That's why more babies are conceived in winter than any other season. Gotta do something to stay warm!

I had the same issue on my XK

 

Greetings. Yes this used to occur occasionally for me as well. It may be a low battery issue for you, but not in my case.
When the humidity is high and the mercury dips the components become ‘glued’ if you will, together.
My remedy: dry and lube the car. But don’t make the mistake that many do:
For locks, hinges, etcetera use teflon / graphite following the drying with compressed air.
For rubbers and seals use silicone.

Many speak highly of petroleum based products provided in aerosol cans... I find that solution merely temporary and extremely messy.

Heading out into the winter cold for some down hill skiing. YAY! . (meant for you, @Cee Jay ;-)

 

 

A quick fix if freezing weather is on the horizon ... take your windshield wiper solution (the blue stuff you put in your windshield washer reservoir) and wipe it liberally on the rubber seals around the windows and doors, then wipe it lightly on the mating glass and metal surfaces. It doesn't harm the painted surfaces, and it keeps the rubber seals from freezing to the glass and metal. Lasts a while for me and my 2007 XK convertible, though this is the first winter in which it's my primary driving vehicle. Worked on my T-Bird for 20 winters here near Pittsburgh where we can have lots of snow, freezing rain, and hard freezes for weeks at a time.
