Hello members

I am writing this post on behalf of my friend who is facing a strange and irritating issue with his Duster.
The model in concern is the 85ps 2015 (old model).

The issue that my friend facesis regarding the air conditioning system in his car.
The AC works fine with the compressor engaged at idle and while driving at speeds of up to 50 kmph , at any higher speed the compressor would cut off and ac stops cooling completely left only with the blower .

Have visited multiple workshops and no one has an explanation for this occurrence.
During the last visit the compressor was serviced, still no change in the situation.

Key points

1) AC works fine at idle and speeds upto 50 kmph
2) At speeds over 50 kmph the compressor cuts off , left only with blower running
3) Rpm does not play a role in this , compressor works fine even at 50 kmph in second gear
4) Compressor restarts when we slow down from a higher speed to less than 50 kmph
5) AC output is very good once the compressor works
6) No increase in engine temperature above optimum , electric fan works fine

Can anybody give your valuable opinion regarding this strange and irritating issue?

Thank you.
