Hi jeff1303. Welcome to the forum. The cause of fuses that blow right away are easier to find than those that only act up once in a while. A simple trick that lets you troubleshoot without wasting a lot of fuses is to make a pair of wires you can plug into the fuse socket then connect them to a 12 volt light bulb. The bulb will limit current to a safe value and will give you a visual indication of when the short circuit in present in the circuit. A brake light bulb works well for low current circuits.
When the bulb is full brightness you can unplug various things to see what makes the bulb's brightness go down. When it does, you have isolated the short to whatever was unplugged. A good place to look for your problem is the wiring harness between the door hinges. Flex the rubber tubes. If the light flickers, or if it goes out when the door is opened, suspect broken or frayed wires inside the tube.
