my AC blows very cold a while then starts blowing warmer. after the car sits a while and is restarted it will be cold again. im told this is the expansion valve or the pressure switch. im confused as to what to do to resolve this.
AC blows cold then warm until car is restarted after sittong a while on 1998 Honda Accord
the system is icing up and cannot produce cold air in that state. the icing may be from a expansion valve malfunctioning. take it to a shop and have them check the pressures and that will verify the findings.
