My windshield fogs up really fast and defrost does barely anything to get rid of the fog. Theres 130k on the car, 1995 gs300. When I bought it at 108k, it didn't ever do this. There has been coolant I believe, or some kind of visible gas/fluid coming through my vents in the past. And recently, when I can my transmission coolant flushed, it got really bad. I cleaned all the fog off manually, and 10 mins later, it was getting fogged up again, even with the car off. I even once tried to block off all the defrost vents and the windshield still fogged up quickly. I've heard of this possibily being a heater core problem, any thoughts? thanks.

Take a good glass cleaner, clean it WELL with a lot of effort. When your done, Take a cloth shirt and wipe off the windshield to get rid of whatever is left

Have you tried the A/C?

 

I don't think would do me much good. I think its more serious than that. I believe whats coming out of my vents is coolant, cause it smells like it, and i can see it. Theres some leaking coolant too, dripping from under someplace towards my rear tires... weird. I tried rubbing off the "condensation" on the windows, which is all the way around my car, front, back, side to side, and my hands were slippery and nasty. any suggestions?

 

Call the dealer and call around some reliable shops and tell them your symptoms. Just be careful and hurt yourself by breathin in toxins and passing out or somn

 

Im gonna replace my heater core, cause thats probably what is causing my issues. Until then, I think im gonna leave it in the garage till i get it fixed
