Interior keeps fogging up! Options

[block]

Mornings/afternoons are fine because there's no moisture built up but once it hits teens to single digit temps my windows would fog the hell up. I've cleaned it with so many different solutions that I've run out of ideas. Turning up the heat doesn't help, same with cooling it. It'll keep building up and im getting sick of driving with fog smears and not seeing at night. I have to wipe every 5 minutes or so lol. I do have a 24 inch crack across my windshield but that should affect be wise I've driven cars with cracked windshield and its been fine. Heater core is good since its blowing hot heat....going to change coolant and see if that helps. Anyone have any other ideas or experiences that may help solve the issue? Sorry it may not make any sense because im just rambling things out from my phones. Thanks!

just turn on defrost with heat and ac on and outside air. you'll have to let it run for a few minutes, but thats what ive done to get it to work here in the teens and single digit mornings... ive always had more trouble on hot summer days after its rained.

In Australia you can buy a spray stuff leaves an invisible film on the window and pretty well stops it fogging up, can't remember the name though

tried that, didnt' work.



i've tried everything. cleaned the front, back, sides about 20 times. made sure it was super clean and sure enough once nightfall comes and i start the engine, it fogs. i dont have issues with it in the morning/afternoons but it's at nights when the temp drop and it's dark. oh well if it doesn't work out, im storing it right back into the garage. im getting a honda crv in the next week or so, so it'll go back to sleep just like last year.

Remove all windows and drive without them. Problem solved

Have a look under your carpet, in the boot etc, you may have some standing water in your car that is causing the fogging.

Make sure the AC is ON when you're trying to defrost. Otherwise you're just blowing moist hot air and it won't clear anything. Common places for moisture leaks: rear fender wells rot out and it gets in there, buildup in the body drains from clogged drain plugs.

I think it's just a trait of Celicas. Both of mine that I actually drove did the same thing.

I dont know but it's pissing me off. I'm closing my house on the 7th of Feb so I'm going to be buying a CRV tomorrow so I don't have to deal with this BS. I hate dealing with this issue because it's quite dangerous to drive at night when I drive home from work. I'll slowly part everything and see if water's somehow getting inside. It'll be a gutted poo poo car anyways since I'll have 4 (IS300, CRV, Corolla, and the Echo) other cars to drive haha...5 if I get a 06-11 Civic Hybrid lol. Oh well thanks guys.

Welcome to the wonderful world of heater cores!!! You're gonna love it here. I just got done with the pleasure of both spending my Boxing Day in my Celi pulling the dash. Wait, I mean the entire freakin interior. Did I forget to mention the savings??? Yup, reach into your savings and grab $391 ($318 if you're in the biz) and hand it to the dealer so they can get a brand new one. Grab your handy dandy AC recovery machine and remove refrigerant. Then undo your coolant lines.
Remove console, glove box, under craps, then remove steering wheel (disconnect battery), pull dash, remove AC box then heater box, blah blah blah.
To make life easier order the little o-rings the hook the stub pipes to the core.
When you pull the core you'll notice the core had a weep inside where the fins are. Hit me up if you need any pointers.
Oh and don't disconnect the harness behind the center vents. You'll spend a few days wondering why your locks don't work.

$318/$391 and you just got ripped. I've replaced the heater core on one of my previous 6g celica before and it wasn't that bad. Oh well, it wasn't my heater core that was the problem. Easy fix was a plug.

The options were $300 from the dealer or $220 from autozone. I chose the factory because it lasted this long and 230000 miles. This cars a keeper for me. You're right, its not that bad, just not how I wanted to spend my day off from work.
