A/c weird issue

[OR VietVet]

Turn off and hissing sound is normal. Sweating is good. The compressor clutch will cycle, not the compressor. Still say it sounds like low on refrigerant. The current refrigerant needs to be claimed and measured/weighed.

Here’s what it does. Went on a 8 minute round trip and it works perfect now even sitting at idle. Dryer looks like this

Why is the cap not on that shrader valve port?

Not sure. It’s new though, the old one had oil leaking out of it and that’s what they swapped when they did the evac and recharge

The cap missing will allow debris/crud to get in there.

I’ll get a cap for it. Did you see the video? Any idea why it constantly is engaging/ disengaging which ties into the air getting colder or hotter? Or are you still thinking it wasn’t charged correctly

I heard the video. I also posted that I still believe the charge amount is not correct. I am guessing without the gauge pressure readings I asked for. At this point, another thing I suggested is to recover refrigerant and get the weight/measure and verify the front and rear a/c system capacity.

Thank you, I’ll take it back and actually get the readings and post them

Need the pressure readings AND the ambient air temperature when the readings are taken since the pressures are directly proportional to the ambient air temp.

^^^^ This^^^... (thx Rock and OR V) HF has an inexpensive R134a gauge and manifold set. Ambient temp measured near the condenser (front grill) and I recommend getting a small thermometer for reading actual vent temp. I saw "fan clutch" in a previous post; I would consider a swap to e-fans, as that will make a big difference in cold air output while idling and at low speeds. 2005+ works, but I prefer the 2010+ (?) for the 7 and 9 blade combo.
