Heater blows cold


Does temp gauge on dash show normal temp? If so problem is with the controls. If sytem cycles through normal controls IE, defroster, floor,bi-level and redirects air properly check to make sure door control is functional for heater core. If door is not opening then you will never get hot air

Ac blows hot air ac compressor is ice cold but the vents blow hot air when enige is hot. bloows cold air when engine is cold


check your air diverter doors, sounds like the door for heat is open, when a/c is selected the doors should move and close the heater off. the heater will over power the a/c. the door controller is located on the environmental station under the dash neat to the floor. the control is electronic and probably not functioning
