The climate control system is “rebooting.” It will do that after any time the battery is disconnected. It should stop blinking after 5-10 miles of driving. If it doesn’t it detected a problem and there will be a stored code you’ll need to have scanned.

On rare occasion after disconnecting the battery the A/C controler loses calibration. To enter the calibration procedure press and hold the power and recirculation buttons for at least 5 seconds, the indicator lights will begin to flash. The calibration procedure takes less than 2 minutes, if any lights flash after calibration it indicates a failure has been detected. The failure indicator should cease after 8 miles of driving.
