Started with a wierd noise every time i locked the doors, or they locked at 15mph. now the only way to open door is from inside, then it clicks back locked immediatly after letting go of the handle. Key won't lift lock enough from outside. no response from unlock, however all other doors acting normal. Also fans occasionally making loud rattling/vibrating noise. Overheated for no reason the other day, let cool down, added water now it runs fine again. Any help or advice would be much appreciated
