I don't know, I have the same question.
It comes out the back of the light housing.
Twenty-five dollars later The marker light is on the same circuit and had to be replaced I also didn't seat the new front blinker bulb correctly
remove the square pop-out on the bumper and there is a screw on the outside of the light
You need to remove the head light, which is rather simple, and reach through the opening from the head light to replace the light bulb for the blinker.
If your "left blinker" is on, to change it, "push up" the blinker arm that is on your steering wheel. If your right blinker is on, push the arm down to change it to the right blinker. This works on All Cavaliers and most other cars made in the U.S.
Check bulb if other side front is working.
change the bulb out for the brake light and that fixes the problem.
There should be a screw or two holding the directional assembly to the fender. The back of this assembly has a light bulb socket which usually comes out by turning it just a little to release the tabs on the socket from the slots in the assembly
As previously said. Dead, or weak battery. The light you're talking about is a blinker signal light, not a check engine light. It's just coincidental.
How can you change the light bulb for the gear shift on a 2002 Toyota Camry?
Probably just a burned out bulb in the front one. Those bulbs have 2 elements so the marker light will still work but the blinker wont.
Honestly? At the junkyard, or on eBay.
