Hi brother,

I am in a lot trouble now a days. Back in June 2020 I get my Liana's gear box fixed, get it tuned and also change all mounds too. Besides, I get its AC got serviced from Magic Motor Model Town Lahore. But after that my car isn't right. Whenever I drove a car on AC my car start getting dead that it didn't gwt pickup after a couple of hours drive. i have to switched off the AC and then shut the engine down for few minutes and then start the car and it works fine. I went back there many times but they unable to diagnose the fault. Before the work car was totally fine. Now the car is start taking load whenever I switch on the AC. The RPM wents below one whenever I switched on the AC and keep jumping up and down continously. Kindly guide me what will be the issue is so I get it fixed.

Asalam O Alaikum

Hope you are well.
For what you have described it seems that the mechanism to increase the RPM upon engaging load on the engine is not working properly. Because when the AC is on the RPM must be somewhere between 900 and 1000.
The AC compressor is making some odd noises or any other unusual rattle from the engine bay?
The worst case scenario can be that your engine compression is weak and that is what causing the stall, this can be a result of compression leak from either intake or exhaust valves.
Kindly consult the following mechanic to diagnose it properly.

Your ac probably has excess gas, the fellow overfilled the system. Get it checked from a qualified mechanic

Behram,

Thank you for your kind response. When I started the engine in the morning then the engine produce a shreeking sound. Also, sometime there is unusual sound of squahing inside the engine too. But this not remains for longer and also, not heard gradually but sometimes. Also, while driving the car on AC for longer than 2hours car start getting dead. Even pressing the gas padle didn't give it accelration. It keeps on dipping and I have no choice to park the car aside and switched off the engine and to restart the car after 5 mins

Also my mechanic asked me to get the car AC compressor check, so does I will do that?
