air conditioner intermittently cools

What is your question?

When it cools, it cools very well! But sometimes it doesn't start cooling until I stop at a red light & take off again. It doesn't want to cool if I am continually moving. Sometimes if I turn the A/C off & on, it will start cooling. It also may be that this happens more often after the car has been sitting in the sun. As said, this doesn't happen all the time. The compressor is cooling! It just doesn't come on sometimes, unless I stop or turn off & on.

What makes this problem better or worse?

turn off / on; stop at a light
