SELF-DIAGNOSTICS
NOTE:Diagnostic Trouble Codes (DTCs) should be diagnosed and repaired before proceeding with any other tests. DTCs can be retrieved using A/C-heater control unit. If no DTCs are set, diagnose problem by symptom, see appropriate test under TROUBLE SHOOTING.

RETRIEVING DIAGNOSTIC TROUBLE CODES
If a fault has occurred in a monitored circuit, the MAN symbol on right side of A/C-heater control unit display will flash during first 2 minutes of operation. To enter diagnostic mode, turn ignition on, then press both temperature ****s simultaneously for 5 seconds.
There are 2 display modes within self-diagnostics: diagnostic pointer and diagnostic value. By rotating driver's temperature ****, one detent in either direction, display is toggled between pointer and value.
Value displayed is decimal equivalent of Random Access Memory (RAM) contents. A "2" is formed using minus sign, and leading "1" in order to display values over 199. Diagnostic pointer mode is identified by a minus sign preceding pointer number. Pointer provides an index, identifying corresponding diagnostic value.
DTCs reside under diagnostic pointer 00. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION table. Pointer will be set to this position upon initial entry into self-diagnostics. If more than one DTC is present, they will be displayed sequentially at a rate of 2-second intervals per fault. Rotating passenger temperature **** will switch self-diagnostic pointers.
A wraparound feature is provided if pointer is continued past either end. Other data used by computer resides under different self-diagnostic pointers and may not be useful in diagnosing A/C-heater system. To exit diagnostics, press any mode button.
NOTE:A 2-digit DTC indicates fault is current. A 3-digit DTC indicates fault is intermittent.

CLEARING DIAGNOSTIC TROUBLE CODES
After a repair is completed, DTCs must be cleared from memory to ensure proper system operation. To clear memory, press A/C mode button.

You're coming up with numbers/letters that pertains to the AC. I figure it will help-since it didn't do you good- I'm sorry too! This is my last post- Good Luck
