Normally this symptom is from low charge. You stated the charge is good. You also say the blend doors are working. Does this system have separate controls for passenger and driver?

[Viettmai]

Yes the 06 tsx does have dual control.

[Dougflas]

Did you check a blend door between driver and passenger?

[Viettmai]

Driver, passenger and mode actuators and doors are working. And relies are all good.
The point that is getting me is that i can get ~65F on driver side if i slightly overcharge the system but the compressor clutch will cut out at 25000rpm. Could this be signs of bad compressor?

Cabin air filter dirty and blocking air flow on one side? I have "repaired" many systems that the only problem was a dirty filter.

Mostly such problem occurs when the solar sensor is not working properly aka damaged. So you should just get it checked. If by God's grace found working, the other options could be getting the air filters and evaporation cores etc. cleaned as these are responsible for that cold breeze coming your way.

Thank you, I'll check it and post after.

So its not the solar sensor.

I had a weekend and took out the compressor and check the system really well. It appears the issue was No/Low oil in the compressor which is why i couldn't find a leak because there were no oil for the dye to attach to. I added oil and now it blows cold air just fine on both driver and passenger. However, it seems that the compressor was damaged and doesn't seem to be able to push at low RPM very well.

SO, now that there is oil in the system i was able to find the leak at the discharge line, I will be replacing the compressor and discharge line when I get parts in.

Thank you everybody for helping me.
