So my turn signal or blinker was flashing quickly for left turns and normal for right turns. The left turn indicator light was on constantly. I replaced the relay and both signals blink normally now. However, the left turn indicator light is on constant if headlights are on. Turn signal switch problem? The switch was replaced 2 years ago. Thanks for advice!!

 

1. Need to know what vehicle you have.

2. Replacing the relay made them both blink equally only because the one you put in is likely a heavy duty one which does NOT have the built in outage indicator *fast flash*

3. Front bulb sockets, bulbs and grounds. In that order.

4. It's not the switch.

 

Thanks Firehawk. 99 cherokee

 

Firehawk was correct. The indicator light for the blinker stayed on constantly because a bulb was burned out.
