When I'm sitting still my ac compressor kicks on and off and it won't cool but when I'm driving down the road it works fine! What might cause this?

No flow in the heat exchanger causing too high head pressures thus causing the high pressure cut out switch to cycle, check and make sure the cooling fans are turning on with the A/C. If the fans are running then you need to get it checked by a professional, 134 under high pressure can do a lot of damage if it blows.

Sounds like you could be short cycling, short of refrigerant.
