Hi all, and thanks for your time. :)
I drive:2001Mazda323f2.0 DiTd 101hp
So i have trouble with AC not being able to cool down properly.I can only measure on low side of Ac line, and my pressures is like this:
Gas is R134a, outside temp is around 25 celsius
Low side static pressure AC off 75 psi (AC was off for 24h at this moment)
Idle AC on (~850 rpm) 15 psi
Drops to 0 psi at 2000 rpm
At 2500 rpm clutch kicks off and pressure goes up to 55-60 psiAnd kicks in again when rpm is idle pressure is then at 15 psi.

So do i need to only add more R134a in it, or there might be some other problem?

AC diagnosis requires a lot of observations and past experience. That single gauge "death kit" that you are using is just not going to cut it. This is generally not a DIY job as you can do a lot more damage than you already have very easily.

The first step in any AC diagnosis is having the known exact right amount of refrigerant in the system and only then will the pressures mean anything. You need to have the system professionally evacuated and recharged with the exact "weighed" amount of refrigerant according to the spec. Only then can you see what the condition of the system is.

Thanks for reply, and i know u are absolutely right about everything. But the problem is i don't have professional service in 100-150 km radius, and biggest problem is i don't have time to go there because of work... When i am free they are closed ect...

I'm sorry about your situation but that doesn't change the facts of the problem. You need professional equipment and knowledge.

If you just try to add more refrigerant not knowing what's in it already, you could do a lot more damage than you already have. Those single gauge kits should be illegal to sell as they are very dangerous.

Sounds like Canada R134 not easy? Fill to spec if you can from a vacuum it will behave. If not this time of year suks fewer places deal with this stuff too regulated for reality.........
