I have a 93 honda civic. The ac works when the car is moving but when the car stops the ac begins to blow out hot air. WHat could be the problem. I have freion and the coils were cleaned out. Or something was cleaned?

Could be freezing-up due to air and moisture forming into ice and blocking off the orifice tube-

This car doesn't have an orifice tube. You need to have a professional set of gauges put on it and get accurate high and low pressure readings and have them analyzed professionally. This could be a bad compressor, inoperative fan, plugged condenser. Overcharged, under charged, etc, etc.

If the condenser is plugged or any of the other things mentioned above, why would the air blow out cold air when its moving? Wouldnt it be hot air all the time, not just when I am at a stop? The air blows real cold while constantly moving and when I stop at a light for more than 30 seconds its like you can hear the change in the sound of the a/c and suddenly all cold air is gone and then after moving for a bout 1 minute or so it suddenly gets cool again. When im stopped the sound of the a/c is very raggedy like the car isnt running properly but if I turn the a/c off it goes away. But I do get the cold air when moving. If the compressor was bad why would I get cold air while moving? Im going to get it professionally checked out as mentioned above with the low and high pressure readings but I dont want to look nieve as a female coming up there so they try to get over on me.

The difference would be the additional air flowing across the condenser and the additional RPM of the compressor. There is a lot to understand about how refrigeration works and it's not something you can learn in a forum post.
