Ac works great on the highway. At rest, hardly any ac cooling at all. Pressure are good, about 45 on the low side and 190 on the high side. No leaks. Condensor fan turns on when ac is turned on, blows strongly toward the engine. I recently put on a new radiator. Could the replacement radiator have fins so tight that it prevents air going over the condensor when the car is at rest ? Other than that, I don't see any issues or have a clue.
