Left turn signal

Look for a bad ground on the circuits. If you dont have a good ground the circuit will back feed looking for a ground. Try it.

Looks like it's the turn signal relay. It should be located on the drivers side under the dash to the left.
Can't see any other way the left light would be steady.
Hope this helps.

Need a new flasher they fail a lot

In this situation you should realy take it to a reputable auto electric shop. Good luck

97 chevy blazer left turn signal makes the dash lights flash then when i turn parking lights on left signal stays on constent when engaged

Probably a burnt bulb. Turn the signal light on, and check front and back.

its your blinker box.. all major lights run through there

If you turn the signal to the left side does the right side stay on? Could be a bulb going bad or the turn signal switch.

What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.

If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.

Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.

If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.

But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.

This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.

Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.

Replace the bulb that stays on and doesn't blink, if that doesn't solve the problem, let me know.
