Check the ground wire.The bulb has 2 filaments in it,one for the signal,and the other for the brake.If the ground wire is broken neither will work.ground a test light and check the two hot wires and see if it lights the test light,if it does,there is an open ground.ground the bulb on that side to the vehicle and see if it works.

Brake light trouble right side brake light will not come on but both flashers work also turn signals work older ford truck what could the problem


I have to think the problem is inside the turn signal switch, a poor internal connection. You know the brake signal first goes through the turn switch before it goes to the bulbs. That is why the brake lights and rear turn signal lights share the same filament in the bulb, and the same wire going to those lights. The only difference is the turning side light is affected by the turn signal flasher, causing blinking, while the other side- the non turning side-does not go through the flasher relay, but straight to the bulb from the turn signal switch. Change your turn signal switch and I believe you will solve the problem. Let me know, okay?

Left bleaker and break light not working. Turn signal works bleaks faster than right side.


Has the vehicle been in an accident on the left rear side. First check the bulb to be sure it is not defective, trade it out with the side that works properly to test. If the bulb works well then My thought are you may have a shorted wire. The turn signal flasher works by heat build up within the flasher the heat is caused by the load of the bulbs, the load heats the metal spring causing it to open the circuit then as quickly as it cools down the circuit closes again lighting the bulbs.
There is also a possibility of a defect in the turn signal mechanism on the steering column. The turn signal switch on many models does three different things on many models that use the same bulb element / or bulb for brake and turn on rear of vehicle. It controls the circuit for brake light by sending power both left and right side rear when turn signal is in neutral position then when turn signal is in left turn the switch cancels brake light power to left side rear and supplies flasher power to left side while maintaining brake light supply to the right side rear, and so on opposite when the right turn is chosen on turn signal switch. The turn signal indicators on the dash normally run off the same circuit as front turn signal bulb only which is also controlled by turn signal switch. Front has turn signals but no brake light.
I think there is an additional load on the left side rear turn circuit and it could be either a wire that is shorted or the turn signal switch if the same bulb element is used for both functions.
Often times if trailer lighting is connected the flasher will also blink a little faster because of the extra load of additional bulbs.

If it is the blinker switch why do I not have brake light on right rear side as well as no turn signal


The brake light circuit runs through the blinker switch, which is how the turn signal is able to override the brake light.

I have a 1990 Chevy Suburban v1500. All lights work except for the Brake Lights and Turn Signals. The Blinker switch on steering column is broken, other than that everything is fine.


Yes, the brake light signal on American cars is routed through the turn signal switch. A new switch should restore both your turns and your brake lights.
American cars use the same bulb filament and same wire to the rears for both brakes and turns. Press the brakes when turning and both rear brakes will light, but since one side travels through the flasher relay, that side will blink, while the other side has a steady light.

2001 Explorer Sport ,Rear Driver Brake Light and Turn Sig. Broke


Rear lights are double filament bulbs one side for the lights other side for the brake/turn signals so it still may be a bulb. Do u have a test light or volt meter you can check to make sure u have power there when brakes or turn signals are activated. Or just try another bulb.
