Blows cold until driving

How many miles on the car? Hard to tell from just what you say but could be your thermostat needs replaced. It's not opening until you get moving. There is a spring that opens and closes based off temp rating. Maybe when you are moving there is more pressure to help it open up as it should I would take it to a mechanic and let them know what's happening. Most good places will give you a diagnosis free of charge.
