Here is the Problem.
When you step on the brakes the dashboard shows the left turn signal (solid light) the front turn signal comes on solid at the same time.
The rear brake light on the left (both) come on. The right side rear brake light (top) comes on but the lower one that serves as the turn signal/brake light does not light up.
The center brake light works.
The left bottom Parking light does not work.
Troubleshooting that I have done.
Tested Bulbs both have the same bulb and if I remove the bulb from the left light and place in the right light I get the same results. Both bulbs are the duel filament bulbs.
1. Test turn signals all work.
2. Test reverse lights all work
3. Test 4 way flashers all work
4. Test 12VDC from the junction block (Rear Brake light circuit board) On C1 pin B (BLUE Plug) I get 12 vdc from pin to ground
4. Test 12VDC on C4 (Black Plug) Pin A I get 12 VDC from pin to ground
5. Test 12 VDC on C4 (Black Plug) Pin G I get 12 VDC from pin to ground
6. Test 12 VDC on C4 (Black Plug) Pin C I get 12 VDC from pin to ground
7. I tested continuity for the circuit following the light blue wire all the way to the Stop Lamp switch at the brake pedal all checks good.
8. When I remove G401 Main ground wire the 2 lights that were not working work now.
What would be my next course of action? Any Help is greatly appreciated.
