Question about 2003 Ford E150
When you depress brakes front and rear signal lights come on,with the emergency flasher relay unplugged from rear of fuse block otherwise all signal lights flash continually, turn signal flasher plugged in to front of fuse block.The service manual only says to make sure you keep the right color and part number flasher relay in the right socket in the fuse block it does not tell you witch one goes were,I have the green plastic(wagner 552/Ford D12B-13350-AA) plugged into the emergancy flasher socket in the rear of the fuse block and the silver aluminum flasher relay plugged into the turn signal socket in the front of the fuse block.I have switched them back and forth and it makes no differance.Both flasher relays work right.If the signal flasher relays are in the right place,what tha Hell is wrong,and causeing the turn signals to not work and the emergancy flashers to stay on when they are not turned on?PLEASE HELP Yours Truelly One at his wits end! John.
If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.
Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
