Q: Hi, I want to ask a question about my car maruti zen, when my car engine is on while i switch on ac button then engine gets off but ac work, and when i drive my car and start ac at second gear then it starts vibration and jerking then engine gets off automatically but ac works on battery load. please look into this matter.
A: I hope this is not the AC problem. Pl. check your engine RPM. If you are using AC the engine RPM must be little higher than the non AC engines. You can test it your self. Start the engine do not on the AC.run for few minutes till the engine gets heated up. Then rise the engine little more than the ideal speed.and keep it like that and press the AC button . If Ac runs properly then there is no problem you have to check the RPM of the engine.
