I cut it and fed it to the arduino only.

What is this that you built? Where do i get the parts to build this? I just got all new AC parts, (compressor, theromisters, expansion valve, dryer,)
Ac Worked great for 2 weeks now fault out about every 25 miles. This AC system is going to make me get rid of this truck.

I got the parts off amazon

I would just go by the part you have listed in that diagram?

Where did you have the work done for the AC? I bet they loaded it with stop leak and dye if they are like the shops I have been to. Try evacuating the AC system and go to Walmart, get four 12oz cans of straight R134A and a small can of Pag oil. Vacuum the system down and put that in, start with three cans of R134A, that should probably be enough. Your AC should blow ice cold, and you did move that ambient air temp sensor up to the windshield wiper cowl, very important.

My AC was blowing ice cold, but I lost the high pressure switch transducer thing up by the high side port or possibly the compressor. Compressor was really icing up on the way home. Going to go get one of those switches today and hopefully be back to freezing my rear end off. If not, new compressor time. Must have sat a bit to long during my adventure. But, it has never worked so good, never.

I'll be installing this solenoid too for the heater core, https://www.amazon.com/gp/product/B01M2W...UTF8&psc=1

Good Luck!

An icing compressor is normally a bad or misadjusted expansion valve allowing liquid refrigerant back to the compressor.

Overfilled system

[Nilao]

Hard to overfill the prostar eith only 3 cans...4 cans in mine and the compressor doesn't ice but the fan runs excessively lol

They did evac the system. I did replace the high pressure sensor. It doesnt ice up just stops running. I can shut the truck off for 30-45 sec start back up, and it runs.
