See if you can put the a/c control head into a self diagnostic mode.

The engine must be running with vehicle not moving.
The Fan Speed set to any speed except OFF.
The Temperature Knob in full cold.
The mode knob must be placed in defrost position
The A/C button can be ON or OFF.
Press and hold the EBL button until the Mechanical Instrument Cluster
Odometer display indicates an "AC00". The body control module  will chime
once and the MTC A/C button LED will begin blinking.
Release the EBL button and wait until the MTC A/C button LED stops
blinking.
The fault codes related to the MTC head and the climate control unit will
appear on the odometer display in numerical form after the letters "AC".
The
diagnostic trouble codes are stored in the BCM and can range between 23
and
51. The odometer display will return to normal operation if no trouble
codes
are found. If a problem is found, then the odometer will display the
letters
"A/C" followed by the trouble code number. The odometer display can only
show one diagnostic trouble code at a time. more than one diagnostic
trouble
code could be in the memory. To scroll through any additional diagnostic
trouble codes, press the A/C button on the MTC head. The BCM will beep
each
time the A/C button is pushed. Continue pu****ng the A/C button and
recording
the trouble code numbers until the odometer returns to normal operation
(note the letters AC will disappear).
