I have renewed almost the whole system in mine - leaks absolutely everywhere. Fix one, another appears.

With mine the first evaporator in dash needed replacement because it was completely clogged with fluff. Being permanently damp, this corrodes the aluminium to the point it becomes porous. None of this you can tell until you have taken so much out that you might as well replace it. When recharged, it is ice cold for about a day and then depletes over the next week or so, but always actually works, so you convince yourself for quite a while that this isn't the problem.

I made the error of putting an AC stop leak into it. It completely clogged the orifice tube and then the high evaporator switch kept cutting the compressor due to low pressure, even when full of gas.

Then there are the wretched push fit connectors and use once 'o' rings, none of which are standard size.

My advice would be don't bother. I've spent thousands over the last ten years and it still doesn't work.
