Did you check bulb, bulb socket, or fuse?

yea checked the bulbs and socket they were good. check the fuse F64 and F66 both looks good. they were working before i take off the bumper dont know if i disconnect a ground some where or unplug a cable? hummm

Try a test light or power probe...I don't know but when you find out, come back and post it! So that way this doesn't become another dead thread, with a question and no answer....please....thank you....good luck.

the body shop my car is at is having the same issue. every thing checks out they just wont come on

Jeffchai

yea i will take off the bumper next week and recheck every thing. might just be something stupid. any one know the exact fuse # for the marker lights on the bumper?

S13REMI

According to the dealer they don't have a fuse since they are tied directly into the ECU, that's why you get the messages that they are out.

Anyone figure this out? I have the same issue after taking my bumper off

Corrosion builds up on the contacts. If the bulbs move while disconnecting from markers, they will sit in a bad contact spot. I have used sandpaper on a flat head screwdriver before to sand off the corrosion between the contacts. The wedge bulbs also have contacts that can move out of position and not make good contact. Check all that stuff. If all else fails, replace with Sunveer E63 or Eurostyle bumper and code them out in Star

Jeffchai

Hummm might be a good reason to upgrade to the E63 bumper :-) haha

You can turn them off with star. Always an option if you can't easily find the issue.

I think the bulbs are #194's grab a set and put new ones in and test before putting back into the slot. You can get to them easy through the wheel well. Just turn the front wheels one way or the other and pull back the well cover. The contacts are likely corroded or the filaments in the bulbs slipped to the side when replacing. Since both are out, kinda leads into other things so a $5 test light will help to make sure.

You are right, they are 194s. For pre-faceift cars, you can pull the parking/standing light which is also 194 and switch them with the side markers to test them out. You then know whether it is a connection or bulb issue. Test light also helps of course.
