I've read the threads on sliding doors and back door draining the battery, this is also my problem. I need to know if there is someway to de-activate this. I use my minivan and a mini-camper. I camp with my cat and need to leave the sliding door open for him to come and go, and I also leave the back door open partway for airflow. Is there anyway to stop from this draining the battery? My cat and I will be forever grateful!
