hi, and thanks...i have a 1993 z34 lumina...with a 4.3 dohc v6...i changed the heater core about 4 years ago....since then i have struggled to keep the car cool when idling, especially in the summer...i have a new radiator in it, new thermosta, new water pump, nd radiator cap...im thinking since i get little to no heat in the winter, maybe my heater core is bad from day 1.... the car is cooler now with the new radiator but it still gets too warm to my liking and i hear boiling when i shut it off...then my a/c compressor dont seem to be engaging when i hit the a/c switch...i used to do this at lights to keep the car cool...but now i blow warm air, my clutch and compressor dont seem to activate...and i get all hot air...from a hot running car...PLEASE help me...im thinking, replace the heater core...and im lost with the a/c unit, tho a guy at Auto Zone told me if it gets low in freon that it will shut off and not work,...if thats true, why dont my secondary fan come on when i hit the switch? help!!! before i blow another head gasket
