On this vehicle the climate was not working despite being charged, it seemed to be a compressor problem because it was noisy anyway but before replacing it we did a power supply check and saw that it was not being powered. From the metstar diagrams it looks like there is a direct connection between the compressor and the climate control unit but they are not precise diagrams... it carries different numbers of fuses which are not described where they are, a more detailed diagram would help.
The compressor is of the type with an integrated pressure switch, in diagnosis I cannot activate it, the only error I can find in the climate control unit is a 9029 referring to the air quality sensor with interrupted contact (if you could find out where it is for a check). Could this be inhibiting compressor operation? Thanks in advance and good work.
