My left rear turn signal and rear side marker is inop. The left front and first 2 side markers work fine. This seems odd that only part of the circuit is inop. I checked bulbs and some fuses----all OK. I plugged in the tow car and they work OK but still no rear bus turn signal. Emergency flashers act the same as the turn signal.
The right side works OK.
Anything short dynamite going to fix this problem!
Thanks
