I have an H3 hummer with an issue i cant solve maybe someone could help me before i take apart the whole car.

My issue the brake light works when i push the brake petal howver when i turn the parking lights on the right side light does not work its the same bulb. The other side of the light works for example the left side parking light works > I tried replacing the bulb didnt solve the issue im assuming its not an fuse as the other side of the parking lights work as well as the brake lights work. I think its an loose ground connection or something.

Any assistance in troubleshooting would be appreciated as if i take it to the dealer it will be an few hundred to fix as always
