#12 How do you attach wires in the fuse box
Incorrect fuse: if a fuse with a lower amperage than recommended by RAM has been installed, it may blow quickly when the lighter or connected accessories are used

Still have doubts about your issue

Make sure its properly seated in the slot to ensure a secure connection

BTW you should check all the fuses if they are fitted tightly as they may be loose from the manufacturer.Please see the picture attached to make it clearer
