Replaced the heater core today. Put everything back together, and start checking things. Had no blinkers. Found out the top connector on the multi-function was unplugged? Plugged it back in, blinkers return. Turn the lights on, all is working. On, my way home. I turn my running light on and have no interior lights or running lights. Blew fuse 4. Replace fuse, turn lights on, blows again. Pull wiring diagram and see that fuse 4 is for the main light switch. If I remove the dimmer, it stops blowing fuses. I have looked at the wiring diagram every which way. The only thing that connects the two is the light blue/red wire and a brown wire. Light blue/red is the illumination wire and the brown goes to the warning chime. They are fused separately........any ideas????
