Ac blow cold air then warm air

[jeanmarcb83]

I have a 2005 Lr3, it happens many time that my ac was blowing cold air then after a while it start to blow warm or normal air. So i should off it and then turn the ignition off wait a while then turning it on so it blow cold air again and work normal. Does anybody have an idea about this problem?
