Left hand interior turn signal light does not come

Brakes are generally not fused seperately. Have u check the bulb in the left side.

it's the grounds if they're both flashing fast it's definitely grounds take a test light and see if its got power goes through the test light grounded to the frame and if the light comes on then it's definitely your grounds

wireing harness short

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

See if bulbs have burnt out in the left brake light and rear turn signal (one bulb if combined) and also rear center high mount brake light.

If the left turn signal has a slower speed than the right turn signal, this is a symptom of a bulb or bulbs burnt out.

Usually, the wiring is not a problem, but I would not rule wiring (or sockets) as a problem out.

Good luck on this repair.

as for the faster flashing thats as simple as a blown bulb, replace the bulb and see if that fixes the problem, it may fix the lot because the other symptoms you mention are a bad connection, if bulb is fine check the connection isnt loose or corroded over. if it is simply file it back to establish better connectivity,

Hello. The symptoms you are describing are likely due to a poor ground. Temporarily install a new ground wire by securing a piece of copper wire to the frame with a self tapping screw. Use this ground wire along with the hot wire to see if each of these lights works. If it does, trace the ground wire back to the frame, unscrew it and clean up the metal with emery cloth so you reestablish a good ground.

check fuse number 7 in Engine Compartment Fuse Box , if its ok you need change turn signal switch

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.

sounds like a bad turn signal switch, wiggle it , just a little bit,... see if some of the lights start to work. do your turn lights work correctly??
