I have got a vitz 2009 model with 2013 registration and using it since 2016. This morning I plugged a mobile phone charger in my car (I have used it previously as well). Everything was working fine I used the AC as well. Once I parked the car and restarted it after some time, the the AC stopped working no air from the fan, when I tried switching on the fan indicator lights stopped working, the defogger light got switched on and started blinking like it is a seat belt sign. Went to an electrician he removed the glove box and he found out a fuse not working. So he changed it and things became normal. After few hours when I switched on the car the same situation and now the battery sign is also flashing for a few second evey now and then during drive.
Kindly suggest what to do and what could be reason.
