Any codes on the DIC?

Maybe check for low freon level.

Wow! I just answered this question on a thread just the other day.

Check fuse #24 to make sure its not blown. If its ok, then its probably your freon charge. Usually the blinking light is a sign that its low and it won't let the compressor run.

Sound like you have low freon. If you dont have enough in the system the pressure switch will not activate the compressor.

Check your HVAC codes. Using the Fuel + options 4 times buttons you can read all the codes. Pay attention to the ones under the HVAC section.

I think that will happen if the fan (blower) is set to too slow. Have you tried increasing the fan's speed on the HVAC controls before pushing the AC button?
