Air conditioning temperature

If it worked before the flush and topping up, then i would suspect it would be the operator and request the system be checked again at their own expense. Switch on your a/c, open the bonnet and check to see if the compressor engages and disengages repeatedly, the compressor is a cylindrical unit being run off the main crank pulley which has its own belt and has a/c lines leading to it. If the compressor cycles, you might be little too low on gas or a clogged tx valve or block in the system somewhere or your stratification wheel on the centre vent is set on "hot" and so fourth. If the compressor does not cycle, you have too much or too little gas to activate the system or your compressor clutch is faulty and again, many other things can also be at fault. Suggest having it checked by a mechanic, which can be found in the "find a shop" tab above
