1987 260E 2.6L

Hello folks,
Today I ventured enough to try and open the sunroof, it went about a quarter way and blew a fuse. I replaced the fuse and quickly quickly closed the sunroof. Whew!!

However a new problem suddenly appears. The right front corner light and the right rear light stays on after I shut the car and turned off all light. That's correct! These lights mysteriously remain lit. I opened the light housings and removed the bulb from the front and rear right side, to conserve battery. I think I am screwed!! Anyone encountered these problems? How do you fix it? Is this only professional job?

Anyone has the wiring diagram for this vehicle? Thanks a lot!!!
