Hello Dear,

I am sure you will find this message in best of your health.

I own Hyundai Santro Club 2004 Model, The car is overall perfect but the problem is, when i turn off the car after drive with AC the car does not start, no any sort of ignition lights in Speed meter not even a click sound come from self. this situation remain for 2 3 hours and then car starts easily. No starting problem at all when i drive without AC. Please guide what it means....?

Thanks & Kind Regards
