Slowwwww defroster, front, not back Options

[96bluevert]

I'm not quite sure why, but my defroster takes for f****n ever to defrost just my front windshield.

Is there any way to fix or "upgrade" the front defrosters.

IS THERE ANY CHANCE THAT YOUR WINDSHIELD IS A LITTLE GREASY. SOMETIMES QUEMICALS USED TO CLEAN YOUR WINDOWS LEAVE A RESIDUE AND MAKE IT HARDER TO DEFFOG.

Try to take off the caps and what the hell is "QUEMICALS" ???
It won't affect the defrosting. With my car when it's cold and windows get fogged I turn on the heat and set it to full window defrost and works. With my wife's 96 ST she uses the A/C for defrosting year around. Only in the winter we adjust the climate to be more warm than cold. Does it have something to do with the chemical in the A/C? I don't think they use freon after a certain year yes? no?

A/C is called air conditioning for a reason. The freon (or whatever the coolant is) is never exposed to the air outside of the A/C system (condenser, lines, compressor, etc). The air is cooled/dried via forced convection through the system's heat exchanger (the big radiator-like object... I feel like that is called the condenser but am not sure).

close but no.... the air that is exposed to the interior of the car never makes it to the engine bay... the freon is pushed through the compressor where it is pressurized... this pressure causes the freon to become colder when entering condensor due to noble gas laws... pressure goes down, volume up, temp goes down (anyone that plays paintball knows this from CO2 canisters... they become freezing cold when filled, the gas is rapidly let out to fill it)... this is pumped into the cabin where the heat exchanger is... air runs by the exchanger and through convection becomes colder (heat will go to the colder region, heat leaves the air and goes to the freon).... the now warmer air returns to the engine bay to go through the cycle again...
the part you are thinking of is inside the car underneath the dash... thats why there is a water outlet inside the car (it comes from inside the cabin) cause it gets really cold and condensation forms and has to be let out... (the water that drips from underneath the car when the A/C is running)

its like a window air conditioner... the air in the cabin is never exposed to the cooling element itself... just a cold area that in return cools the air

Semantics, but PV/T = P'V'/T' begs to differ The coolant in the system cools when it expands in the condenser. Pressurizing the gas in the system is done by mechanical means, by doing work to the gas (compressing it, ie lowering volume). As the gas is compressed, both its pressure and its temperature rise. As the gas is pushed through the lines into the condenser, it keeps its high temperature and pressure. When it enters the condenser, however, it rapidly expands (adiabatic expansion) and drops in temperature and pressure drastically and turns into a liquid. It then cycles back into the compressor, which turns the liquid back into a gas through pressurization, etc. Hence, phase change system, uses the energy requirements of a phase change to alter temperature.
