Customer reply replied 8 months ago
The headlights work both sides. The only the blinker that works is left front. When I turn four ways on, only left front works. No brake lights
Customer reply replied 8 months ago
No right blinker in any setting normal or 4 way
Technician: Wayne, Journeyman replied 8 months ago

Thank you for that

Reason I asked you mentioned left head light works

so head lights work both sides

I still think you have aground issue

run jumper wire to the Turn/ switch

On steering column?
Technician: Wayne, Journeyman replied 8 months ago

HI

NO, I said that wrong I meant to rear light

Wayne

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 8 months ago
I have power to the rear lights only when headlights are on. No power for blinkers in either normal or hazards
Technician: Wayne, Journeyman replied 8 months ago

Thank you for that

Well that is saying the turn signal switch is at fault

you will need to replace that

Wayne

Customer reply replied 8 months ago
I get the different turn signals showing in the gauge cluster
Customer reply replied 8 months ago
The turn signal is also causing the no brake light issue as well?
Technician: Wayne, Journeyman replied 8 months ago

HI

Yes the circuit runs thru T/S also for the brakes

Wayne

My wife followed me and she said my third brake light in the center but the others do not. Do you still think it’s the blinker module?
Technician: Wayne, Journeyman replied 8 months ago

Hi Brian

Thank you for the reply

did you say you change the bulbs??

If 3rd brake light is working, I suggest to replace the bulbs

or check the socket

Wayne

Customer reply replied 8 months ago
Correct only left front blinker comes on with hazard on and only left front blinker when using turn switch. All other blinker lights are non operational
Technician: Wayne, Journeyman replied 8 months ago

Thank you Bryan

You have a ground issue, I suggest t o run a jumper

to that light and see if it works

Wayne

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 8 months ago
If it’s a ground issue it is causing all of the blinkers except left front from working. That also includes all of the brake lights. When I turn the running lights or headlights on I hear the relay click for power. On the gauge cluster the green lights blink for the right and hazards but the actual blinkers do not blink except for left one
Technician: Wayne, Journeyman replied 8 months ago

Morning Bryan

Did you try the ground as I suggested ??

Wayne

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 8 months ago
you are saying start with a ground jumper on the right blinker and see if the blinker works? Wouldn’t the the yellow light that is part of the running light system use the same ground as the blinker?
Technician: Wayne, Journeyman replied 8 months ago

Hi

not always , they have separate grounds

it could be a bad socket

Wayne

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 8 months ago
I just don’t understand why there is no power to multiple lights all at once. If just one light I would agree to run a ground to that particular light. I think there must be a common ground for all of the inoperable lights or some type of relay/ power problem
Technician: Wayne, Journeyman replied 8 months ago

Hi Bryan

I will opt-out of this question

maybe another expert can shed more light on this issue

Do not reply or rate me as question gets locked back to me
