CVT judder seems to have been sorted with a fluid change, grumbling rear wheel bearing swapped, it’s now time to see if we can get some chilled air out of it.
The switch illuminates, but no rev drop or drop in vent output temperature.
So it’s booked in to go an aircon machine (do they have a specific name?) later in the week. No idea how long it hasn’t worked, so we’ll see.
Question is - do I get a new dryer for it before attempting to regas it? Or if it works after having been regassed, will the A/C circuit have to be split again to change it?

If the a/c hasn't worked for some time because of loss of gas, then I'd suspect the circuit has been open to the atmosphere and hence water vapour. In which case I'd suspect it would need a new dryer. You may be lucky and get away with it working for a while with just a re-gas, perhaps long enough to flog it?

No intentions of selling the car, it’s for a newly qualified driver to get some experience. We have a family history of only parting with cars when they’re heading for the breakers.

Sounds like the clutch on the compressor, hold your hand on it while someone turns the aircon on, you should feel a 'clunk'. Nice to have but its not the end of the world.

If your getting a clunk then a regas and leak test is the next step.

Get it pressure tested . Regas and leak checked. Very likely to be the condenser leaking. Pretty common on the jazz . System will shut down if there’s insufficient pressure.

As I understand it, pressure testing an A/C system consists of checking it’ll hold a vacuum? Which has always puzzled me as surely that’ll pull seals tight together, instead of checking for leakage.

I understood the pressure test is positive pressure using nitrogen - only if it holds pressure is the refrigerant gas is added - unscrupulous workshops just add more refrigerant without the test.

Even if it holds the pressure the hoses will be old and it would probably be worthwhile changing them also. You don't want a hose to blow in 12 months time and then need to pay for another regas.

Just had it regassed and it’s outputting icy cold air, on what’s quite a grey, wet day in the N-W.

My neighbour has the same car . Re charge last week. Pulled out 225 gms and refill with 450 gms . Checked both cooling fans working and system cooling good .
