When you start the vehicle up and turn the fan on it should blink some codes at you, well thats what the lights flashing will be doing. if it just needs to be reprogrammed you hold the buttons on the left down for about 5 seconds with fan on full high and setting on full cold. the two buttons you hold are the very top one and the very bottom if my memory is correct haven't done this in about 6 months or so. It will then go into a reprogram mode if it can be reprogrammed it will stop after about 5 minutes. if not you most likely need a new control head. Let me know which lights are flashing and how many times.
