I have a 92 Accord. My turn signals work, but the marker lights (bumper lights) don't. The passenger side marker light stays lit constantly, even with the ignition and blinkers off (it only turns off if I disconnect the battery). The drivers side marker never turns on. Both sides have a constant 12 volts (so it's weird that the drivers side won't turn on. The wiring diagram shows a ground wire that attaches to a ground strip(?; not sure what you'd call it) where several other properly working components are grounded, and a power wire that goes to the ICU. Since that's all there is to the diagram, I replaced the ICU at $175 only to find out that's not my problem. Does anyone know which wire sends the signal to the ICU? Perhaps my problem is in that wire. Thought it might be the flasher unit, but as I said the turn signals work properly. As usual with lighting issues, the turn signals blink fast, while the hazards blink at normal speed. All bulbs are brand new. Thanks for the help.
