[V8] Too hot for A/C to operate?

[Jeremy Ward]

 Brad, have you tried pulling the codes for the Climate Control? Very easy 
to do and instructions can be found on Chris' website here:

 I had problems with AC last summer, specifically with the pressure switch. 
When I held down the outside temp and off button, scrolled to channel 01, I 
was getting an 09 error (ignore as per manual; not all V8s were equipped 
with this sensor) and 16 which was fixed by a new high pressure switch.
 Pull the codes (while it is failing) and let us know what you find out!
 Cheers,

There's an overheat for the engine temp to disable the compressor (its
way up there), and over/underpressure switches for the AC system that
will disable the compressor.
