Strange behaviour of battery drain

[mudassar1972]

Hi friends

For the last one week i have faced an issue twice whereby i go to my office and park the car around 8am in morning however when i return around afternoon 5:30pm the car locks are open and there is absolutely no power or current in the car, no lights in dash , keyless remote , start button not working etc.. after the first occurance i got the car jump started and replaced the suspected battery. However new battery went fine for 2 days over weekend and again the same behaviour repeated when i parked the car in office. Now this is Bahrain and the outside temperature and sun can be 46 degree C ++ . Today i drove the car in the morning around 8 am and then parked it at home , took other car to office and when i returned in the afternoon around 530 pm the car opened with keyless remote and there were no issues in starting it.

One important thing that after jump starting the car second time the center vents of AC are not giving any air flow only side ones are working despite changing the air flow to foot or front windscreen etc. The GPS has also reset its location to default.


i need help to diagnose the issue of this intermittent behaviour

MY car is Landcruiser 200 VXR 4700 petrol 2009

thanks

Check current draw with everything off. Not sure what amp draw should be, maybe 10 milli amp. If excessive, start pulling fuses to isolate current drain

Current draw with all off is 10 - 11 amp. i have not driven the car today but still it is starting without need of jump start. what to do next ?>

got the car checked at dealership they say battery and charging system are OK . Should i reset the car by removing battery terminals , if yes how many minutes to wait for disconnect ?

Since no body is replying , so i thought to update the experience. The dealership confirmed no issues was power or charging. The diagnosed the AC front ducts not working due to issue with servo motor. i remember it made sounds and maybe it got stuck due which it was draining battery. Since the motor is dead i will not observe for another 2 - 3 days to check if the battery drain occurs

Any update on the fix? I'm looking at a 200 that has some servo issues, and the estimate to repair is extremely expensive. Curious how you dealt with it?
