OK lets see if the car can tell us anything with its self diagnostic system. Here is what you will need to do to see if the A/C system is holding any codes.
1. Turn on ignition. Press RESET button on DIC to see if any warning messages are pressent. Press and hold the OPTIONS button on DIC. While holding the OPTIONS button, press FUEL buttion 4 times in 10 seconds. System will enter automatic display mode followed by all DTC's (diagnostic trouble codes) present for all information systems. To enter manual display mode press any button except the E/M button as this will exit diagnostic mode.
2. Depress and button of DIC (driver information center) to enter HVAC mode of manual diagnostics. Make sure to write down all current and old DTC's. These DTC's will be a B followed by 4 numbers.
3. To clear codes - Turn on ignition and press the RESET button on the DIC and then press and hold OPTIONS and while holding OPTIONS press the FUEL button 4 times within 10 seconds as before then go to HVAC as before and press the RESET button in that mode and this will clear the codes.
Get back to me with any codes and I will look them up and see what it has to tell us. Thanks
