1978 F150 output temperature variation

[57chevyeddie]

Good evening. My name is Eddie. I’m working on my 1978 F150 AC. I installed a new Classic Auto Air unit in my truck about a year ago. The temperature at my center vent varies 15 to 20 degrees as I’m driving on these hot days. My temperature goes down to 37 and up to 57 over and over. I just fixed a leaking condenser line and recharged it a week ago. I vacuumed the unit down and put 24 ounces of R134 into it. The guages read 35-40 low side and 275 high side with ambient temperature around 90 degrees. The system cools good but climbs to 55-60 degrees while the compressor is off. I’ve checked my water valve. Bypassed the heater hoses. I lifted the thermostat tube about an inch from inside the case. Monitored my engine water temperature. I’ve contacted the tech support at CAA for advice.

This is a OEM truck with no bell or whistles. The only thing that’s not stock is the CAA air conditioner unit. It has performed this way since day one of use.
I will gladly consider any ideas that would clear this up for me. Thanks in advance for the advice.

Hola a todos, soy madre de dos ninos pequenos y estamos pensando en unas vacaciones en Tenerife. Me atrae mucho la idea de hacer alguna actividad en familia, y he visto que hay paseos guiados en moto de agua que parecen atractivos y poco comunes. Sin embargo, quiero saber si estas excursiones dejan subir a ninos tan pequenos como los mios, que tienen menos de 6 anos. ?Alguien sabe si las empresas que organizan estas rutas permiten que se incluyan ninos de tan corta edad? Tambien me genera dudas la parte de seguridad: ?que tipo de proteccion y medidas preventivas se ofrecen para los ninos durante el recorrido? He encontrado cierta informacion en el apartado de FAQ de una empresa especializada, pero no queda muy claro si hay normas de edad o modificaciones en las motos jethub tenerife . Si alguna familia ha probado esta experiencia con ninos, ?podrian relatarnos su experiencia y que sugerencias ofrecen? Me serviria saber si es realmente seguro y si es mas adecuado otro tipo de actividad en el mar para los peques. ?Gracias por cualquier consejo o experiencia que puedan compartir!

I joined a small listening club that compares ordinary headphones with simple spectrogram views, and we recently noticed a few unusual streaks in AI-generated music. We are not trying to diagnose every mark as a problem. Instead, we want to learn which visual details deserve another careful listen. I found this visual reference while searching for explanations that do not promise certainty. It helped me frame the image as one clue rather than a verdict. I usually play a short section first, then inspect the same place on the display. The listening habit should stay calm. Each brief observation needs an audible reason. I compare individual passages before drawing conclusions. The process remains simple for new members. A focused listen can prevent us from chasing an imaginary issue. We keep repeatable notes about what we actually heard. The group should remain patient. Our examples need to stay concrete. Every careful observation remains possible to revisit. I keep one note short for discussion. I would rather ask a question than claim certainty from one picture. How did you learn to connect what you hear with what you see without turning the display into a shortcut? Thanks for sharing approachable examples.
