Turn Signal/Cornering Lamps
The HZDT/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal/hazard flasher module and have ground at G202. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. The T/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flow is from the turn signal switch assembly to the turn signal/hazard flasher module. The turn signal/hazard flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators. The left turn signals have ground at G106, G400 and at G402. The right turn signals have ground at G105 and G400. The turn signal switch supplies battery positive voltage to the cornering lamps, the left cornering lamp has ground at G105 and the right cornering lamp has ground at G106.

have you checked the bulbs front and back. to see if they work, bulb check. then it sounds like you might have a bad signal flasher that only works the left side and not the right side. or if a bulb at the front or the rear gets bright but not the opposite bulb on the same side then you may just have a bad bulb or socket or power to the socket when doing the bulb check.

flasher/blinker is busted. this is located under your dash board. remove steering column cover, turn on LEFT turn signal (yes, the one that is working), then you will hear a clicking sound. locate the relay that causes the sound. there you can see 2 relays (one for LEFT, other one for RIGHT turn),replace busted one.

---------This will help.Thanks.

Need to replace the bulb. There are 2 filaments in the bulb. 1 works parking light the other is turn signal. It flashes fast to alert you that it has a blown out bulb.

If it is a factory trailer package then there are fuses for the left turn signal and the right turn signal for the trailer connector. Check your owners manual for the location of these two fuses.

All this runs though the hazzard button in the dash. The light in it gets hot and eventually shorts the system. It is fairly easy to replace if you have small hands. I think the new button is around $20. This happened to my alero and also my moms alero. Solved the problem on both.

the next step and almost certainly the problem is the turn signal switch, have seen this symptom on other years around yours and switch fixed it.

Check the terminals inside the bulb socket also you could turn on right side turn signals and while holding socket in hand move wiring at base of socket to see if you might have wiring problem if that is ok leave signal and start moving back harness to see if you have a broken wire.

bad ground on right side
