2009 prostar eagle marker lights

There has to be a fuse some place! I can't believe these lights are controlled by the ECU? If they are factory installed lights I'm sure they are fused some place. I'm sure there will be someone through here in a while that will have an idea.

 

marker lights are controlled by the body controller (pin-G) off the plug. the wire should be labeled (1603). This is the feed for the markers off the body controller. First check all your fuses to the body controller in your fuse panel, then check to ensure none of the wiring is shorted to the marker lights, then lastly, make sure your steering column marker interrupt button is not shorted. Quite often, when a fuse for the cabin controller goes out, your jake bake will not function either, but is not always the case.

 

Marker lights are indeed controlled by the body controller. There is no fuse for those lights. The body controller can detect how much current is being drawn. If there is a short, the body controller will not power that output until the next key cycle. The marker and tail lights come out of connector 1604, or labeled J2 on the out side of the body controller. The body controller is mounted to the inside of the cab next to the clutch pedal. The wire number is A54, brown in colour and 16 gauge in size at location G. This is only output for the marker and tail lights. The one wire splits into three shortly after and go their separate ways. One lead to the hood markers, one to the tail and the other up to the cab clearance. The wiring to and at the body controller are famous for being tied way too tight and breaking or pulling out. You could pull that side panel off to expose the body controller and wiggle the wiring to see if something has come loose. There could also be a short in your lights somewhere too. You could unplug the marker lights at the hood and tail lights one at a time, cycle the key, and retry the lights.

 

Just got a ticket for no marker lights. Recycled the ignition and they came on....now I'm looking for the tail lights on the body module.....this Truck is a headache!

 

Thanks HeavyD I couldn't have fixed it without you. And thanks to Al Gore for creating the internet.

 

and thanks to WildChild for telling me about his ticket, you helped me get it done faster.

 

Thanks heavyd, you're a huge blessing on here
