Parking light wont light up

golf4283 -- I havent touched the colum wiring at all cuz i felt the problem was somewhere else.. and no i havent replaced the switch.
That was gonna be my next question, by changing that would that help... idk i just had a feeling it was a bad switch.. but thanks.Im going to change it out and see what happens
 
There are places that one can follow the voltage on its route from the fuse box to the rear lights.

Do you know someone with a volt/ohm meter and knows how to use it? A few minutes of looking at a schematic and taking a few measurements by a knowledgeable person would have saved you a lot of time replacing parts that didn't need replacement. Not meant as a criticism, only an observation after the fact.
 
Just a simple test light is all you need. Check the black wire/terminal coming out of the light switch. It carries the voltage to the rear taillamps/lic plate lamp.
