relay problem?!! need help!!!

[obsolete]

hey guys, i was just putting in the ml320 clear sidemarkers on one side of my '91 and it doens't turn on. so i checked the other side and the rear sidemarkers and they are all out except the driver's side rear. what do u think the problem is? relay? fuse? bulbs?

[the head]

check in this order
fuse
bulb (hook up to a light you know works)
Relay (flasher module)
basically if your turn signals light up and work it is really unlikely it is your realy

[obsolete]

which one is the fuse for the side markers? and i couldn't understand th e lastl line,

if my turn signals come on , then it's most likely NOT the relay?
