Mahindra And Mahindra — ac not blowing cool air consequent to hissing noise

Address:

534201

I purchased a mahindra scorpio, lx model from raychand motors (Steel city properties private limited), vijayawada on[protected]. The registration number of the vehicle is ap37bh8668.

During the month of march /april 2017, m & n motors, undi road, bhimavaram, andhra pradesh replaced ac evaporator. Since the day of its replacement, i am facing with hissing noise below the dash board on speed above 70-80 kms per hour and after 3 to 4 hours ride, the ac fan doesn't blow cool air or no air or blow very low air that is insufficient to stay normal in such condition.

I complained this issue immediately to the workshop, they tried to address but it is beyond their competence to do it. Then onward they are trying to rectify through some arbitrary means without proper knowledge about the functioning of car ac. This naturally resulted but my problem doesn't get resolved.
I admire my existing vehicle, scorpio lx and run 105, 000 plus kilometres on the current vehicle, but i am a little bit hesitant to purchase another vehicle from mahindra brand due to its poor competent technicians.
I request you to arrange for solving the -
- ac hissing noise; and
- not blowing cool air after 3 to 4 hours of ride.

Thanking you
Yours sincerely
