my saturn aura XR 2007 .... the heater does'nt get warm

How long does it usually take for a reply??r did I do something wrong?

IF YOU HAVE NOT CHANGED YOUR ENGINE COOLANT AND HAVE MANY MILES ON THE SATURN YOUR HEATER CORE AS WELL AS RADIATOR ARE PROBABLY CLOGGED WITH THE COOLANT/ANTIFREEZE. OEM COOLANT WAS DEXCOOL WHICH HAS A TENDANCY TO TURN TO, ESSENTIALLY, MUD. IF THAT IS THE CASE THE ENTIRE SYSYEM WILL NEED FLUSHING. TAKE IT TO YOUR REPUTABLE SHOP (NOT GM AS THEY WILL OVERCHARGE) TELL THEM THAT YOU DON'T HAVE HEAT. THEY SHOULD RECOMMEND A FLUSH AND FILL. THEY WILL REPLACE THE DEXCOOL WITH CONVENTIONAL ANTIFREEZE/ COOLANT AS WELL AS REMOVING THE HEATER HOSES AND FLUSHING THAT CORE ESPECIALLY. IT IS MONEY WELL SPENT BECAUSE ONCE THE CORE IS CLEAN YOU WILL HAVE HEAT FROM THEN ON.
