Does this mean the AC compressor needs to be replaced. Or is there other alternatives.
AC not working. Only hot air comes out. on 1998 Chevrolet Prizm
You need to bring it to a shop so they can check the system for leaks.
not enough info..problem could be electrical..relay,switch or PCM ,not signaling compressor 'on' or the blend door may not be changing position (controls airflow through heater core & a/c evaporator) symptoms ? noises ?any other issues with engine?? any clicking from comp. clutch when a/c switched on/off? .Also if heat is blowing through te vents with the fan on high , turn the temp dial from hot to cold and back again . Is there any noticable difference in the air temp? If so , then you have coolant going through your heater core (normal) If it was air going through the heater core then you would most likely be getting air through vent closer to ambient (room) temp .
