Customer may experience A/C switch light going out or blinking and      
warm air from vents when operating blower motor in the number 2         
position for long periods of time.                                      
                                                                        
Repair Procedure                                                        
Request specific fan speed during failure and note in H/L file.         
                                                                        
If condition only occurred in the #2 fan speed, condition may be the    
result of a logic error within the heater control print board.          
                                                                        
The logic of the print board was changed by increasing the check        
voltage threshold for A/C compressor engagement with the blower motor   
speed set in the #2 position from 1.0V to approximately 2.0V

If condition occurred in another fan speed, have dealer inspect system  
connections, and confirm with customer about air flow from vents.       
condition may be the result of system freeze up. if so please note in   
H/L file subject line.
