Brake lights wont flash and turn signal wont flash

Fuse sure didn't play, bulb is unlikely to be all bad. Check the turn signal switch, first find the turn signal switch plug, put the key to ON file, in trying to find a turn signal lamp switch wire (flash to the thread) will this wire with no light ON one side of the turn signal line connected to see if a turn signal light, the light is turn signal switch is broken, or the plug contact undesirable, don't light it is turn signal switch to light ON one side of the light path, in order to determine whether the light bulb is broken can open a small lamp or led brake lights to borrow their wire leads to a turn signal whether turn signal light, so you can determine whether the light bulb not bright side is broken.auto diagnostic tool.

Sounds like a ground problem to me. Bulbs are not getting there ground to complete the circuit so they backfed through the other bulbs.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

check all the ground connections that's a good place to start get back to me if you need more help Thanks Ray

you have lost ground to the right light unit, good luck

I suspect a bad multi function switch located in the left hand side of the steering column. This switch controls your high/low beams/wiper delay/windshield washer/turn signals and hazards.

change relay turn light indicators

Will your Center High-Mount Stop Light (CHMSL) illuminate when you depress the brake pedal, but the lower/outer lights will not?
-- Do you have to hold the signal lever in a certain spot to get the turn signals to flash?
-- Do you have to hold the signal lever in a certain spot to get the lower/outer brake lights to illuminate?
-- Will the signals work in one direction, but not the other?
If you answered yes to any of the preceeding questions, your turn signal switch is likely malfunctioning.

**One more question before we continue: Is the turn signal lever not "cancelling" (returning to the "off" position) after you make a turn? If this is the case, you have a broken "cancelling spring."


Before you begin disassembly of your steering column, verify the turn signal flasher is not malfunctioning. If your brake lights work fine, but not the signals (either direction,) then it's likely the flasher is burnt out. The flasher itself is located underneath the dash near where the steering column passes through the firewall

sounds like a bad turn signal switch

start with a fuse, then go on to a turn signal relay. turn the level left or right on the steering column with the inginition switch on, if the light in the dash lights up but won't flash, it is the turn signal relay.
