A vehicle set for about 1 year prior to it sitting and parked the blend door actuator was clicking and I was able to use two vents for heat and the other two vins for air conditioning. Now that it has sat the air conditioner will not blow cold and when I'm driving down the road the fan will kick on for no reason at all. I no longer hear the blend door actuator clicking but the heat works.

Which fan kicks on the blower motor or the radiator fan? The A/C system sounds like it is low, here is a video and a guide to help charge the system and simple things to check if the system is not working that you can go over.
