Angry defroster problems

I have a 2007 wrangler unlimited and am severely disappointed with the how it cannot keep the windshield or side windows clear. We hit -15C earlier this winter and the side windows are are frosted up and the bottom left corner of the windshield is frosted up as well. Today we hit -45C and the side windows were frozen solid and about 1/3 of my windshield - drivers side was frozen up and this was after it was running for about 1 hour. The dealership says the defroster is working as it is designed!!! Any comments, suggestions?

you may want to change the concentration of radiator fluid to make your rig run hotter.. or try to partially block the radiator itself.

I'm sorry, I have not been in that type of environment, so my experience is severely limited.

as for the -15C (5F) it should work better than that, but at -45C (-49F) I dont think that any car would perform as designed under those conditions.

The major reason why I'm quite upset is because my previous jeeps did cut it. I've owned a 98 renegade and a 2002 wrangler -- cold was never an issue with them. That is basically the reason why I did not even think twice about heat when buying this jeep. Thanks for your input.

I agree with you on the poor performance of the defroster. Have an 07 Unlimited and my 05 TJ kept the entire windshield clear. I keep the side windows clear by aiming the vents directly at them, but this takes away from the air flow to the windshield. What is needed are plastic covers over the left and right corners of the defroster outlet to aim hot air at both bottom corners of the windshield.

I'm so glad to see someone else is having an issue with the design of the '07 -- at least I know I am not dealing with a lemon. I am still going to have to do something though, it's not cool having to drive looking out the passenger's side of the windshield.

You wouldn't have ANY of these problems if you just left the top off like Jeeps are suppose to be...

With the same temperature on both side of the glass... no issues!

Yeah, but on second thought you might have to bundle up and wear so many clothes you might not be able to operate the radio controls...
