Design Flaw - wipers freeze up when driving in cold, wet conditions
 
In addition to the issue with the remote start not defrosting this windshield, this morning I was "pleasantly" surprised to find myself suddenly driving with zero visibility when I tried to wash the salt from my windshield. I had to pull off the road - unable to see where I was going - to bang off my wipers.

I pre-heated the car for 10 minutes using remote start, but still had to clear the 1/2 inch of snow from the windshield before driving (because the remote start doesn't take care of the windshield). I banged all the snow & ice off the windshield wipers and turned them on & off to make sure they were wiping well. They were, so I pulled out and started heading to work. I kept the HVAC set to blow on the windsheild, with the temp set to "Hi" and the blower speed set to four bars. Note this - it was blasting the windshield pretty good with the maximum temperature setting.

After about 10 minutes at about 40 mph on a two-lane, it was time to wash the salt of the windshield. The sprayers covered the glass with juice and the wipers wiped, only they didn't remove anything! The wiper blades were frozen solid. I couldn't believe it. I had to pull over, unable to see where I was going, so that I could get out and bang the wiper blades.

It turns out that the wiper blades sit a few inches below the windsheild and do not benefit at all from the defroster. They are left in the cold, literally, and as such they freeze up when you're driving in these kinds of conditions. As a result, when you do need them, they do nothing.

I have a strong hunch that Chrysler engineers & marketing folks read this forum. I hope they do. If you're listening - this is going to get somebody killed. My guess is the wipers were tucked down low behind the trailing edge of the hood to help reduce drag and improve fuel economy. Well, fat lot of good fuel economy does when you can't see where you're going and you run head-on into a Brinks truck.

If you received vehicle questionnaire from Jeep in email (I did) make sure to let them know about this and other problems

Oh, yeah. Need to do that. I'm going to hit the character limit in my sig soon!

I didn't receive this. How did they get your email address?

Doesn't sound like a feasible factory fix without major changes.

My selling dealer gave it to them. I do have several annoying design issues I reported to them. They also ask you to provide your phone number (I did) if you don't mind them giving you a callback.

I agree. And I'm dumbfounded that it was designed this way. The wipers simply do not benefit from the windshield defroster.

The spider-type wiper blades do freeze up in the winter. That's just how they are. You'll need some winter blades (with a rubber boot over the spider) or just some beam-type ones (like the Bosch Icon).

I am a little annoyed that they sit so low that their resting position doesn't benefit from the defroster (neither is there any heating element there), but freezing up while driving is more a combination of the blade style and weather conditions than anything else.

I never had a problem with spider-type blades on my KJ Liberty. That's because on there the blades rested on the heated portion of the windshield. On the WK2, they do not. On my Tacoma, the blades sit low like they do on the WK2. Like the WK2, they do not benefit from the windshield defroster. I have been using beam-type blades on there for a few years (Bosch Icon) and have had them freeze up as well, but never like what happened to me this morning.

every car that I have owned/driven (from POS to luxury cars) has had the wipers freeze up on me when they are not use including today with my KK. If you want the problem fixed, buy winter blades.

Whats next? your car is using gas instead of water....

The wk2's use gas?? That is unacceptable!
