As the title says. S4. Parking lights and tail lights dont work. Brake lhe mps work when I step on the brakes though. Unplugged the.switch and saw that there is a burn spot on the connector.

Am going to try another switch but do you guys think ill have to replace the harness as well?
Are s4 and s5 headlight switches the same?

 

Yes, replace the short headlight switch harness. Sfive and sfour are not the same.

A search would reveal about ten gazillion posts/threads on side marker lights and tail lights not working.

 

Yeah I ended up researching into it and found a thread... I do appologize for a redundant thread.

Thanks for the info
