My windshield lately has been fogging up a lot!!! Even the regular manual defog setting doesn't clear it. I have to use the actual front auto setting to clear it all the time which means my A/C is on. Does anyone know why this is happening? BTW I got the auto climate control.

 

Try replacing your in-cabin filter

 

Oh, here. I found a similar post that might be of some help. is this similar to the problem your having?

Sounds very similar. My windshield was replaced awhile ago (some may remember my flying Ice incident). Its an OEM replacement. I am a smoker, however my original windshield was not that bad. Maybe its a cleaner I used. I will try that first before looking into the in-cabin filter.

 

Yeah, smoking is definitely a factor in this problem, but if it's worse than your original windshield, I would suggest try a different cleaner first like you said.

 

mine used to do that...I replaced my cabin filter...and it diminished (maybe it was all in my head or something)

who knows but like Kyle00 said,

 

I had serious problems in the winter with a foggy windshield so I cleaned the in cabin filter and it basically eliminated the problem.

 

word,

 

Any funny smell ? if so it may be a possibility that the heater core is leaking, they seem to be made cheap, atleast in the 2000 max, its a aluminum core but the hose connectors are plastic and screwed onto the core and theres just a O ring to prevent leaking.
