After the air conditioner is turned on in summer, the participation of the air conditioner compressor will definitely have a certain impact on the power of the engine, especially for cars with small displacement, which is normal. However, if your vehicle has been in good condition before and suddenly has problems recently, accompanied by a decrease in power and an increase in fuel consumption, it is recommended to check whether the engine control system, including fuel injection and ignition, is normal. Besides, you mentioned that the generator is often damaged after turning on the air conditioner. It is recommended to check whether the generator is matched and whether the battery and charging system wiring harness are in good condition.
I hope the above answers are helpful to you, thank you!
