I bought a used cultus 2018 few days back ...its AC performance is not optimal at all...moreover its performance drops down further when the car is idle...i took the car to a workshop , they changed the valve, pipe and topped up the gas, and said AC would work fine...it worked well for 2 days and after that, its performance was not satisfactory at all...now again i took it to the same workshop and they told me its compressor needs to be changed(which will cost around Rs 80,000)...Then i took the car to another workshop and the guy there said he would install the compressor of toyota duet and charge 20 to 25,000 rs...i am so confused and worried at the same time ....does any cultus owner here have the same problem with AC ?And whats the solution ...pls help
