Defroster without a/c

[pengyou]

In most if not all cars, I thought the a/c kicked in when the defroster was turned. How does a defroster work on a bus without a/c?

Rain-X makes an anti-fog solution. It comes in a black bottle, rather than the normal yellow. The stuff works wonders.

Long before they tied the defrost to the a/c it was just a high volume of warm/hot air. Until the 2000s a/c was an option.

like others have said.. the defroster just pushes warm air.. it doesnt work as well as a refrigerated defrost.. opening the front and rear section of the driver window about 2 inches each will help.. it sucks out the humid air and lets in some outside air..

in my DEV bus, i installed a refrigerated defriost just because I like that feature of a car.. (and I wanted dashboard A/C)..

Rain-X is a rip-off. Use Turtle Wax instead.

I've used the black bottle antifog stuff in a truck of mine and my experience was that it made the windows fog up easier. External rain x works wonders but the internal stuff I can't recommend at all.

While on the subject...

A farmer told me to wipe down the inside of my windshield with a plug of chewing tobacco to keep it from fogging. Tried it on my old jeep and damned if it didn't help! Use it un-chewed BTW.

PS...I do NOT chew tobacco.
