First.
I have a 1997 Civic EX automatic.
Second.
My Car runs hot whenever i turn my Cold A/C on. about 3/4 of the way up on the temp guage.

Second
My car runs at normal temp. whenever i turn the heat on, although the heat usually blows cool unless i have it above 2000 rpm.

The summer is coming pretty soon... i need to know what to replace.. any help is appreciated. :-)

you are low on coolant. add some

And check to ensure your fans are kicking on (though only the coolant explains the heating problem).

What shows it, the reservoir? I recommend you let the engine cool for about an hour, open the radiator itself and look for how much fluid is in it. Also, hopefully you don't have 100% coolant in there, you have to have water mixed in or it won't work properly.
