[s-cars] Climate Control Diagnostic Codes

[batchelder]

First thanks to all who responded to my recent post about the "Bucking"
and "whooshing" at high RPM's.

The problem was indeed the Michilen Man hose.  I replaced it and all is
well again.

My next question regards the meaning of the following code from the
on-board climate control diagnostic tool.

In trying to troubleshoot problems with the A/C, I checked all the A/C
channels and found no error codes.

The only thing I found was during the graphical display of the 88.8 is a
message that refers to:

  "Slippage or blockage, A/C Refrigerant High Pressure Switch, 120x off"

Does anyone know what this means?

Thank you,

Jed
