Is the compressor spinning?
Is the electric fan on? Is it cooling at all? Condensation on the pipes past the header tank? Is the centre vent switching between hot and cold? If it'll switch ECON on/off then the HVAC unit thinks there is enough gas, which comes from the pressure switch on the evaporator. Its becoming increasingly common for the valve blocks to fail and allow hot water through constantly, meaning even if the AC is running ice cold, you still get a face full of hot air. Marcel and I are working on a solution for this which is not tested yet. |

Is the electric fan on? Yes, running fine. Is it cooling at all? Not cooling at all, fan on high speed. Condensation on the pipes past the header tank? No condensation, pipes appear to be warm to touch. Is the centre vent switching between hot and cold? No discernible difference when switching from warm to cold on centre vent. Am I looking at Valve block replacement or finding a learned AC person?

Well this became odd. Sort of.
Took the car in to be checked out and it was found there was very little gas to recover from the system. Lines were checked for leaks and none present. Refilled and has been ice cold for the last 24hrs with all controls working. ![]() Sorry if I mis-directed you chaps.

Vexing because it had numerous new parts and seals. It might need some dye injecting and then going over with a blacklight to see if the leak is visible.

Sounds a bit like my D4, tested ok for leaks but only about 70g of gas recovered. Refilled to I think 780g.
Glad you're all sorted.
