Good morning! I have a 159 with Lima automatic year 2010 registration plate EK126FE which has air conditioning that suddenly lets out room temperature air. Can I blame the expansion valve?
Trials carried out:
1)Recovery and injection of correct gas quantity
2)the friction pulley is in traction even when air comes out at room temperature.
3) the high and low pressures are correct but they drop suddenly and as a result the climate does not cool.
Can the compressor have a similar defect?
