I turn the climate control to 90 degrees and all I get is cold air even after the engine is warmed up. There is no overheating issues and the average cooling temp is always between 200-215 degrees. What should I look for to fix this problem?[/quote:a6d3deab79]

put your hands on the heater hoses, watch out they may be hot, if both hoses seam the same temp, see if your air mode doors are working, if they are cold replace the thermostat, if one is hot and one is cold, remove the heater hoses and use a hose and blow out the heater core, if still no heat, heater core may be pluged
