Air conditioning will not blow cold

Welcome to 2CarPros.

Unless there is a leak in the system allowing pressure to escape, the compressor should start when a specific pressure threshold is reached. Do me a favor. Take a look through these links and let me know if anything helps. Also, I need to know how you are recharging the unit and was it the engine coolant radiator that was replaced or something different?

The links cover a couple different techniques for adding Freon. Since I'm not sure which you are using, I'm including both.

Let me know if any of that helps or if you have other questions.

Take care,

I suspect you may have damaged one of the connectors at the condenser. That is the think in front of the radiator that actually looks like another radiator. That is my first suspect for a leak. The condenser and condenser block are attached to the radiator. Although you don't have to drain the Freon or take any of it apart, something is most likely leaking from the work.

Did you take apart the condenser?
