You're right. Excuse me while I go set mine on fire.

As for the defroster, I've found that it's generally reluctant to engage when in automatic mode. I usually prefer it to be in windshield/floor mode most of the time in the winter, I end up overriding it if the weather is anything but the best. This can put more heat onto the windshield, but the wipers still sit too low for them to get much heat.

I've not had an issue with them icing while driving, but I haven't driven in an extremely cold ice storm (about what it took in previous vehicles to pull that off). What I've experienced is that once I clear them, they stay that way, but weather conditions from place to place vary- I can easily see how they'd keep icing if we lived further north.

They're probably going to have to put a strip of heating element down there to fix this, but I don't see how it could be retrofit.

EVER. Like NEVER, EVER EVER, or just EVER?

I have nothing to add to the icy wiper discussion, since I live in TX, but I couldn't resist responding to this hyperbolic statement. If mine were stolen I would be looking for another first model year JGC this weekend.

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

I have only had mild icing conditions so far this winter, so have not yet had the wipers actually freeze solid to the parked position low on the windshield while driving.

But, even though I have changed to a beam type wiper, I have seem them start to stick down there in between intermittent wipes when at highway speed (i.e. start to freeze, but broken free again by the next wipe). And this is with generous use of -45C wiper fluid. Never happened before on any of my previous vehicles, including three Jeeps.

I can see how they could be a real problem in severe freezing rain, and could be my first quality issue.

I hope Jeep is looking at fixes for this problem. As I previously suggested, if a modest amount of engine heat was allowed to get underneath the parked wiper position, the problem could be solved. Or, maybe it needs electrical heat. Engineers, start your calculators!

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

My experience is as follows:
1) -10 up to -20, not snowing, I can use the wipers even with the water, no icing
2) -4 -5 snowing, the snow is spread by the wipers and icing occurs. Whole windshield is cover pretty quick. I use the water fluid and windshield is cleared

I believed this is not as bad as described here. I experience similar behaviour as my previous cars ... if the windshield is cold, you will always have icing issues, if the winshield is warm, there is no way you will have ice on it ...Of course, I would like when I step in the jeep, all the snow to be cleared by pushing a button, tempreture to be warm, eventually a hot coffee seved, wipers cleaned and all the ice melted ... not going to happen

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

You know if you put your ac controls on defrost before getting out of the car it will defrost the wind shield when you remote start the car.

For me and apparently a few others that have chimed in recently, it is exactly as I have described.

Round and round we go. ostroveni, read back through the thread to where I explained how I deliberately cleared every bit of snow from the car before driving, started with a dry windshield and wipers that worked well, only to have them freeze up after a short period of driving with intermittent wiping. NHWK05, read back to where your suggestion was already made by someone, but it was dismissed as missing the point. Of course one could do that, but to do it one would have to disable the HVAC comfort program. Why have said program if it does not work? The point of the complaint is that the HVAC comfort program is less than optimal.

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

JPSmith,

I haven't experienced what you have with the WK2 yet -- my driving conditions haven't been too extreme.

With my Silverado I would experience what you described, though. Windshield wipers freezing up in sub-freezing conditions when used on intermittent. I found, though, that if I switched them over to full-time, they would pick up enough warmth from the glass to de-ice and stay defrosted.

What were your results when you tried this with the WK2? Similar?

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

How difficult would it be to add some defrosting wire (like the rear window) to the windshield under the wiper area?

I actually did try this. It ended up causing smeared icing to occur around the top 1/3 of the windshield. I think it was spreading the wee bit of precip so thin that it would freeze very quickly. This was with the defroster set to full-whack and the temp set to "HI."

Ambient temp was in the mid-20s. It wasn't an arctic tundra, btw.

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

I dont own my jeep yet, but when i went to the dealer to test drive an overland, it was about -25degC and snowing pretty good. Figured it was a good time to test this thing out. The sales guy pulled it up to the door from the lot. it was covered in snow(6-8 inches all over) he just gave it a good brushing off( similar to what you did) all the snow was gone. then we took it out. I had no problems with the wipers at all keeping the window clear. it was probably sitting outside warming up for 10 minutes.


OFF TOPIC:
One thing I did notice is that the QLII did not work properly. I tried to raise and lower it when I got in at the dealership but nothing happened...sales guy said it was prob too cold...hmm. So i drove it around town and on the highway for prob 10 minutes, pulled into a parking lot and tried again. this time still no luck just gave me a "service Suspension" error in the display. So do i take this as no QL use in cold weather. It frequently gets below -20degC where I live and gets down past -40degC somedays.

It would be a challenge. You could buy one of those repair kits that allows you to "paint" on electrically conductive defroster lines. But that would have to go on the inside of the glass and it would obviously be very difficult to paint grid lines between the base of the windshield and the dashboard. Then you'd have to wire them up with a switch and proper circuit protection. And even if you managed to do all of that, I'm not so sure that they'd put out enough heat to keep the wiper from freezing. Just look at this picture of the wiper heaters on a Subaru. They look like they can put out some serious heat! I think this is something that Jeep should have done for the WK2, since it seems to be an issue.

Nope, there was something wrong with the one you test drove. My QL works just fine at -20 C.
