OFF! -Burn more calories by sweating them out... sorry, but that's the truth.
A little, the ac pump will put a draw on the engine more than without the ac on.
Driving with the windows down and AC off at lower speeds is more fuel efficient. At higher speeds(45+), having the windows down will create more drag and it is more efficient to have the windows up with the AC on.
On
dries out your eyes
Yes, but not more than 13 - 15 volts, or the headlight filament will burn out.
they get to hot/there is not enough cooling
it is supposed to, its an ac cutout switch that turns off ac compres to give you more power or acceleration. it can be bypassed
Why does your ac and heater fan turn off and on
to turn it off on pleasant days
yes, because the ac runs off the engine and puts more stress on your engine and has to work harder.(work hard waste gas)
The AC is taking energy
No. The bulb will burn out.
