Today I visited the Motor Expert I-10/3, Islamabad for check-up the AC of my car. Met with Mr. Shazaib, very humble person and told him all story about problem.
He asked the AC Mechanic in his presence to check what is the exact issue with AC Cooling. Mechanic said there is less gas in compressor that's why cooling is minimum. There is no problem with AC Compressor, dry bottle and expansion valve,they are working excellently. There is no need of changing all on them. Only gas would be filled plus throttle body cleaning as well.
Gas charging cost me Rs. 1500 and throttle body cleaning plus throttle body calibration cost me 1500, so total I paid is Rs. 3000 whereas Outside AC Mechanics told me total cost 13k to 14k.
Thanks to ALLAH ALMIGHTY for saving my money.
Results:
Problem is solved and AC cooling is perfectly up to mark. Cabin is too cool.
Throttle body cleaning plus throttle body calibration make the accelerator pedal to soft and pick is also improved with AC.
I also recommend all of you to visit Motor Expert for vehicle Check-up.
