Welcome to 2CarPros.

The first thing I need you to check is the light sockets. Make sure they are not melted down inside and causing a short.

Next, I need to know if the brake lights work, turn signal, or anything on the right side other than parking lights. I attached a schematic for the right side lights. I circled the fuse 7.5 amp which I believe is the one you are replacing. You will see the wiring goes all directions, so I need to narrow things down with more specifics.

Also, never place a higher amperage fuse in place of a lower one. Fuses are selected based on wiring gauge. What can happen is the wire will melt down before the fuse blows and it can cause a fire.

Let me know.

Do any of the lights work on that side? Have you checked for power at the socket? Have you checked the sockets for corrosion or damage due to heat?

Yes, I have checked the sockets and my headlights work, my blinkers work, my brake lights work, but the taillight and front marker light is out. It is blowing every fuse I put into it and the car has a habit of flipping the hot wires to ground.

I need you to check for a short to ground. It sounds like you are right. Disconnect the battery to do this. Check for continuity to ground on the power supply at both the front and rear bulb sockets. One should have continuity and the other should not. If they both show continuity to ground, then it's time to start tracing wires to find where the short is located. The black wire should be ground. The others tested should not.

Let me know what you find.
