question
 

If you remove the A/C, what happens to the heater?

you cant remove the AC unit unless you make custom ducting to the blower unit

or you can buy the duct from a car that didn't come with A/C..

or you can remove the compressor and thing infront of the rad and leave the ac stuff in the dash in place.

i am also curious as to how to remove my ac, seeing as it doesnt work anyways

Is there a better cooling efficiency after taking out the condensor? It sits directly in front of the radiator and and blocks mostly all the flow

i didnt mean the a/c unit, i meant the a/c pump to save weight. Would i also lose the heat?

Heat comes from a fan blowing hot air off the heater core. Hot coolant goes through the heater core. Nothing to do with the A/C compressor under the hood. You can remove the compressor and the radiator thing that is for the A/C. Just follow the lines from the compressor. I think its called the condensor. Just follow all the lines and remove anything in its path that isn't under the dash.
