Parking Lights Side Markers Out?
 

I set up the Front Side Markers as Blinkers- they worked great for over a year. No LEDs, simple clean waterproofed install. No fuses are out- but I replaced the bulbs and fuse just to be sure. They don't come on with the running lights or with the blinkers. I noticed this about a week ago and have been trying to figure out WTF is wrong. Connections are good, no corrosion. Front Running lights and front blinkers work fine as well as the back. Does anyone know the wire to run down at the kick panel for this? I followed the light green at the switch on the column- but of course it's good as the running lights up front come on. :Wconfused

Did you use a Mutimeter and check voltage and resistance in your wiring?
