BMW Repair: Parking Light, short fuses, light fuse

Question
Ok. So here's the thing, I've been having problems with my signal lights for quite some time. I've gone through fuses blowing, and replacing relay switches. I then thought about what could the cause be for something to short fuses, and ruin a relay switch multiple times. So what I did was I checked all the fuses which could possibly be related to signal light failure. So looking at what each fuse does, I saw a seperate fuse for the parking light. When I unplugged the fuse for the parking light, I noticed that the driver side would go out, but the parking light for the passenger side would stay on. So I decided to check all the bulbs on the passenger side of my car, and when I checked out the rear bulbs on the passenger side the light turned off. So I put the Parking light fuse back on thinking that the problem was fixed a new problem has risen. The signals now work fine, but the new problem is that now the parking light for the front and back on the passenger side doesn't even turn on anymore. So the problem has switched to where it signals fine, but parking light is off.

Answer
Make sre that you are installing the correct type bulb in eack socket. Single or double filiment. I don't mean to be condesending to you of coure. Also a lot of weird lighting or central locking problems can be broken wires in the harness to the trunk lid. I would pull back the rubber boot and take a look.
