The Good News:
Side Running lights work
Head lights work (High Beams and Low Beams)
Fog lights Work
Turn Signal Lights Work
Reverse Back Up Lights Work
The Bad News:
Emergency Flasher Lights work except right Rear Light flashes very dim
Only the Left Brake Light Works
I purchased all new bulbs (Running lights, Head lights, Tail Lights and Backup Lights)
I swapped Tail Lights to confirm that the problem is not the bulb
I followed the Brown Wire from the rear right tail light to the plug located just under the dash on the drivers side
When I press the brake pedal, there is no current going to the Brown Wire (from under the dash) but if I move the turn signal for a right turn, there is current to the Brown Wire. My turn signals work great.
Please correct me if I am wrong:
1.) The rear turn signals, the rear emergency flasher and brake lights use the same filament in the rear tail lights
2.) The brake switch has a White Wire that is connected to the turn signal switch
3.) When I press the brake pedal, this White Wire must complete a circuit in the turn signal switch to activate both brake lights
4.) Both the Dark Green Wire (Left Brake Tail Light Filament) and Brown Wire (Right Brake light Filament) should be getting power when the brake pedal is pressed
5.) The problem is probably located in the turn signal switch
Your assistance is much appreciated. Should my next move be to pull the steering wheel and check the turn signal switch (maybe the emergency flasher switch as well)?
Thank you!
