You may need to replace your Thermostat or your Heater Core.
MAKE sure that is the problem.If heater is blowing cold air,reach on passenger side,under dash,and find the heater blower,and gently pull the white plastic piece to make sure it is not stuck on cold.They go from hot to cold easily but not back to heat.
under dash, pasenger side
on my 99 Sephia the Blower is located under the dash on the passenger side.
MY WIFE HAS A 99 KIA SEPHIA. SHE HAS HAD NOTHING BUT BAD LUCK OUT OF IT. ANYWAY THE HEATER MOTOR IS LOCATED UNDER THE DASH,RIGHT BELOW THE GLOVE BOX. I HAVE TO BEAT ON HERS WITH A RUBBER MALLET TO GET IT TO WORK.
