I've had my S13 for 2 years now, & have always had the problem of intermittent A/C operation- where for no apparent reason would run when it wanted to when the A/C button was pressed, or would not.
When it did run, would shut off anywhere for 5 to 20 mins. or so.
Traced the problem to the Thermo Control Amp. It was plugged in, but if you jiggled the harness wire around, would instantly start or stop the compressor.
Hope this helps someone
Kevin
