My A/C is full of Freon, my dad is a mechanic and double checked it. The heater works but the A/C will not blow cold air. The compressor is working fine. We are starting to think blend door could be an issue. There is no clogs in condenser he said. I was going to see if you had any suggestions. Thank you

We need a little more information about how he checked it and what he found. Did he check the A/C pressures high and low side? If not, we need to do that.

Let us know what the high and low pressures are and we will better know what the possible issues are. The most common issue is the compressor is turning on but it is not operating. Meaning it is not building the pressure so it is the issue.

If the A/C system checks out then we will be able to move onto a possible blend door issue but we need to start with pressures. Thanks
