AC poopy-ed the bed, and it's summer in las vegas
My AC started turning off maybe 3-4 seconds after it is turned on, with the AC button light flashing.
Exactly what it does is
you turn on the AC,
it throws the RPMs up a tiny bit, as if the compressor is engaging,
you can almost feel the air getting cold,
the AC light starts flashing, the air keeps blowing, but normal temperature, not cold
the engine then sounds like the compressor is not engaged
I ran the climate control self-diagnosis by pushing the auto and recirculate while turning the ignition to on, and it gives me a code 00, which is normal
I took it to my friend's shop and borrowed their "AC machine" I sucked the refridgerant out, checked for leaks, no leaks, refilled it.
It does exactly the same thing after recharging it.
Any ideas? I was thinking maybe the compressor is bad, but I didn't thinka bad compressor would even turn on like this one does. I also thought it could be a valve, but wouldn't the AC ECU pick up that as a code?

Clutch
I'm a tard. What does the compressor clutch look like, how do I find it, and what does it look like when it is moving? lol
In all seriousness, I have no idea. I only know the AC compressor is low on the drivers side of the front of the engine, as that's where I hooked up one of the hoses to empty/fill the refridgerant.

If there is no leak, I would guess refrigerant pressure sensor might b taking $h/t??
On newer cars, if the pressure sensor does not see proper pressure, it will not engage compressor clutch prevents from breaking down if it were to run without refrigerant and oil.

Quick way to check if you have another car with properly running ac,
With engine running with ac
1. Do not unplug sensor. Tap into wires.
2. Take volt meter measure value across the 2 lines on both cars.
The car with good running ac is the reference
I the voltage signal is way off from the car with good running ac, then I would try ac pressure sensor.

turn on the ac and add 12 directly to your comp and if the clutch kicks in (it on the front of the compressor) then you have an issue with pressure of the ac system, pressure switch, or a pwr relay for your ac. you can test your pressure switch by jumping it with a paper clip and if that kicks your clutch over then your either your pressure switch is bad or low freon pressure.
make sure you try to spin your comp clutch with your hand first though, the clutch should move freely. most bad comp clutches will lock up and not allow you to move it much of not at all. gl

mine also blinks.... sometimes that is. it does blow cold air, but not cold enough so i keep it on low that way the air is cold bc if its on high it wont be too cold. anyways it takes a while sometimes i go thru the whole day without blinking... but i think its blinking bc i'm low on freon so ill find out for sure when i fill up with freon. on the bright side i have a spare compressor . let me know if you need it..
