I was wondering if i am the only one that gets lots of condensation inside TC. when it rains lower front windshield really fogs up especially if i have ac on. Also at nite my windshiled fogs up alot. I was wondering if everyone has this problem or if its just me.

 

it's you and the weather in your area.

turn on the defrost?

 

i do turn them on but it still fogs up. even on defrst on alot of air come out of the dash vent. with ac on condensation occurs outside so i need to remove it with wiper. Also sometime my rear view mirror fogsup

 

i usually turn off the a/c when there's weather that makes your window fog.. and also open up the vents as well (recirc off)

there's a rear defrost that has never failed to clear up the rear window fogging for me.

where do you live??

 

near philly. i never had this problem with any other car i drove. rear is fine with the defroster its the front. it doesnt seem to happen in winter but it does happen in summer especailly when it rains. it gets to a point so i can see but it never clears up . do u also get air cming out of the vents on the dash when you are in deforst mode?

 

Never has happened to me...defrost usually works like a charm.

 

If you have the defrost set too cold, it will condensate on the outside of the glass. Try turning the temp up a bit and it should stop the condensation for the most part.

 

Condensation forms on whichever side of the glass is significantly warmer, like you see on the outside of your drink glass with iced beverage inside.

Good trick is to mist your wipers once - if the windshield clears it's on the outside, so like engifineer said make your defroster temp warmer.

If the wipers don't clear it, you're fogging on the inside - so run the defroster colder.

Either way make sure the A/C is on when defrosting to take out humidity.

 

Curious what's making the problem worse....I had this problem for a few days as well as feeling a lot of hot air around my legs under the wheel and realized that when I ran my power wire for my amps through the hole in the firewall near the steering column I didn't reseat the boot very well, perhaps that's your issue?

 

all these smart guys helping him out and nobody has suggested that he turn up the fan speed yet?

 

That will make it worse. As mentioned, if it is condensating on the outside of the glass, the defrost is set too cold, so turning up the fan would just make it worse.

 

Make sure you're set to fresh air, not recirc. On Defrost, the A/C unit will turn on to remove the condensation.

Also, make sure the A/C drain tube is draining outside of the vehicle and not inside. Do you see a puddle under the car after running the A/C?
