wen i turn my lights on to the running light position, my corner lights dont work but my tail lights work. can someone tell me wat the problem is? i've checked fuses and they are all still good.

 

Did you check the bulbs. I won't go into all of the reasons why these corner lights go bad on a semi often basis.

One of many methods for DX electrical issues is to start at the "load" in this case the lights and work your way back to the powe source. You probably need to invest in a test light or even a multi meter. Then check for power at the socket. From there follow the harness back and check at the next junction point, or somewhere along the harness if a broken wire is suspected.

 

the bulbs are all still good.

 

Then you need to start tracing the harness back. In some cases you can just go straight to the switch and check there. I don't now if there are separate feeds for the parking lights vs. the head lights. I'd suggest looking in the faq for the manual and grab the ETM....that is if it's in there.....
