But all of this is speculation.

If all the input tests prove OK, the multiplex control unit must be faulty, replace the under-dash fuse/relay box assembly.

The A/C compressor will cycle for a few seconds and the air out of the vents is warm at best. Today, I kept cycling the temperature control knob from cold to warm and back. After 3-4 times, the A/C stayed on and blew cold air for the next hour.
