Where's my answer
Expert:  James replied 1 year ago.

I wish diagnosing AC was simple. The first thing you need to do is rent a gauge set from the part store. Once you have this you can determine if you have an overcharge or undercharge. If it works sometimes but not others I would suspect a faulty orifice tube. Especially if you added R-134 yourself. All DIY 1134 you buy has sealant inside the can is damaging to the system. I would evacuate the system correctly and remove the orifice tube and look to see if it is plugged with sealant. That will cause the concern you are having.

Ok but the system was full and didn't take any r135 so now what

Need more info. How do I do it. We're is everything were is everything located
Expert:  James replied 1 year ago.

Just because Freon won't go into the system doesn't mean it isn't low or overcharged. When you start the vehicle does the compressor turn on and cool the vehicle down?

I'm not happy with your answers I am not satisfied abdominal do not want to pay please give me my money back
Expert:  James replied 1 year ago.

You aren't happy with my answers because you don't have the correct tools to properly diagnose the vehicle. That is usually how it works. I asked you another quetion to help with no additional info from you well AC isn't easy to diagnose especially since you aren't willing to invest your time and tools into repairing it.

Customer: replied 1 year ago.
it does
Customer: replied 1 year ago.
I am willing to invest my time and money please don't be rude I payed for help
Expert:  James replied 1 year ago.

I am sorry if that came across rude. That wasn't my intention. If the concern only happens while pulling your trailer its possible to have an air flow problem. If you aren't getting good air flow across the condensor after driving awhile the AC performance will begin to suffer. Usually If you drive on very dusty road this happens. It usually plugs up the condensor between the condensor and the radiator. I would inspect in this area for any blockage.
