Hey everyone! Your local Ranger Gal here. I need some help.



My 2005 2.3L AC has stopped working.

Here is the symptoms:
AC will, at random, blow cold. No specific amount of time. Sometimes it is 15 minutes. Sometimes it is 10 seconds.

It will mostly blow hot. Much like the temperature outside (Sunny Central Florida).

I have recharged it, added more of the Refrigerant and had pressure on the compressor(low pressure side I believe it is referenced as in the manual), and it blew cold in the cab. The compressor had condensation and I can hear it turn on/kick on. So I assume the compressor is healthy.



What could it be?
I know there is a switch in the actual panel, and there is a "Heater Valve" that differentiates between hot/cold.
I just don't want to start buying items and replacing stuff for no reason. AC parts are not cheap.

My credo
Give me money.
The blend door actuators are notorious for failing on these trucks. Usually when they fail they simply stick in one position though so you'd just get constant hot or constant cold. If it's randomly switching from warm to cold my first guess would be the temp switch on the panel itself. Second guess would be the high or low pressure switch on the AC line failing and causing the compressor to stop running.
