I haven't personally experienced this, but a good first step with these types of issues would be to check the cabin air filter I would guess? Do you get a good amount of air coming out of your other vents when you have them selected?

 

It's the outside of the windshield that is icing up. Inside defrosts ok

 

Do you set the heater to defrost? - Never had that problem on any Honda I owned. It does not send warn air to the windshield except in defrost.

 

In some temp/windchill combos you need to either keep the heater air stream on the windscreen or towards the cabin, off the windscreen to avoid the effect from a triple point where the heater can barely melt the snow and the wind chill can precisely freeze the part you had melted. This will repeat until the heater won't have any effect any more.

There is a situation where nothing works but it's rare. I keep a spray bottle of undiluted alcohol based windscreen fluid in the trunk to deice during a break.

 

Never had that problem if you keep defrost and full blast heat. We get down to -40c (-40F) here and only in highways where we need to do that.

 

Climate control settings in your CRV? As in.. auto climate control or manual?

Autoclimate control works best, and it can and will use the AC to clear fogging on the inside of the cabin glass, and that could in fact cause further chilling of the glass which would then collect and freeze water on the front surface of the glass until the cabin is suitably warm to shed ice on all the glass surfaces.

Keep in mind, when your front glass defrost system is active (which it will be under auto climate control) the system uses a combination of low moisture chilled air from the AC in combination with warm air for cabin heating.

Really? in my 2014 the auto climate control sucks, mine works best on manual when I set it where I want it.

 

I think the problem is that the defrost is not heating as high as it used to, I will get it checked out and use some deicer in the meantime, thanks everyone

 

While my 16 has gone, the last long distance run I did in early December, had snow for over 150 miles from NJ to Mass. no issue at all with snow build up. It was sticky enough snow to ultimately disable the ACC.

So things to check list include settings you are using. Ensure hot Air to windshield. I typically run with hot air to feet and windshield. Check coolant level. If minimum, add some more.

next time, take a photo To show us.

 

I have the same problem with my windshield wipers icing up on my 2013 CRV here in CO. The wipers work fine at first, but while I have the wipers on, with it snowing, the ice forms on the blades and no longer clears the snow/melted snow/slush off my windshield. I have changed wiper blades, just replaced the arms and today, on my way home from work, I had to pull off the road to get the ice off my wiper blades, since I could no longer see out of the windshield. I never had this type of problem with my pilot. Did you ever find a solution?

 

Do you not have a button to lower left of steering wheel on the dash that turns on the electric windshield defrost, apparently uses a lot of current so they say not to leave on for a long time, but defrosts area near bottom of wipers

sorry just noticed on Canadian models only

 

Don't use auto climate control, and turn on the recirculation so that only cabin air is being used, and not outside air.

 

I don't have auto climate control, I just have defrost on full blast. I will try keeping the recirculation on though. Thanks
