I have a 1998 Mustang Gt and the ac worked great for a while until it starting blowing hot air one day. I checked to see if the ac clutch was engaging and it wasn’t. I did the jumper method with the low pressure switch and the compressor kicked on. So I replaced the low side pressure switch, and it’s still blowing hot while the ac clutch kicks on for 2 seconds and off for like 5 seconds.. I’m stuck.. any ideas??

Just wondering.............

Are you positive that:
  • The coils are clean
  • That the fans work
  • factory fan shroud and air dams in place
The post does not state:
  • The outside air temperature
  • the temperature of the air exiting the air vent
  • the low pressure reading
  • the high pressure reading
There are cases where it would be "normal" for the AC to cycle.
