I have been having A/C issues. vehicle will blow warm air when A/C is turned on cold, lately it will rarely blow cold (only in the morning). I have checked the pressure in the high port and it is good. there is no leak, and my condenser looks to be free of debris. Could it still be my condenser or my compressor?

Welcome to 2CarPros.

It could be several things, but to truly identify the cause, I need to know both the high and low side pressures when it is running. In addition, I need to know the outside temperature when it is checked.

Most people check low side pressure. Since you checked high side pressure, I assume you have manifold gauges. If you could, let me know both sides. It could be low on Freon.

Here are a few links you may find helpful:

If you could, let me know the pressures and temp when tested. It will be very helpful.

Take care and I will watch for your reply.
