Turn on the hazard switch (emergency blinkers). You should hear it under the dashboard on the drivers side. The emergency blinker and turn signal are each controlled by a different relay but the relays look alike. Once you've located the emergency blinker relay, the turn signal relay is nearby.
under the dash
Remove the panel under steering wheel. There will be 2 flashers. Replace one on right.
take the wheel well out first then reach in and turn bulb socket
Pull off panel under steering wheel. You will see two separate flashers. Replace the one on the right.
If memory serves, there isn't one. All that switching is done at the turn signal/low highbeam/cruise control stalk.
There is no relay. The flasher in under the dash on the left of the steering column
Pulling the turn signal switch toward you should switch the lights to the low beams. If that doesn't work, you may have to replace the switch, which means replacing the entire turn signal stalk.

Low beam bulb burnt out? Replace bulb. Bulbs OK? If the dimmer switch is also the turn signal/cruise/headlight on and off switch, you probably have to replace the entire switch.
This question has come up several times. The answer seems to be to remove the housing around the steering column and look underneath. There are two flashers. Replace the one on the right. but don't quote me, OK? I stole this answer from one of the other posters
To replace a turn signal switch on a 2003 Pontiac Aztek, also known as a flash relay, the steering column must be removed. The flash relay is located under the turn signal. Remove the mounting hardware and the unit can be taken off.
It looks as if I'll have to crawl under the front of the car to access the bulb to replace it.
You need to replace the failed TURN SIGNAL lamp. Select turn signal selector to direction which flashes fast then check which exterior light is out. Go to any auto parts store. The light usually costs under $5 and can be replaced easily.

You've got to disable the airbag and remove it, then pull the steering wheel, .... go to www.autozone .com for more detailed instructions. hope that helps. Ron
camshaft sensor - signal low could be that or check the wiring to it. Other possibilities MAF or TPS
first: remove the black plastic radiator cover (push-pins) then remove the two bolts holding the headlamp in unplugh the bulb harness and remove then you should see the turn signal housing. unplug the harnes and there are 2 small screws to remove.
Remove the front inner wheel well splash shield. Grasp the bulb socket and rotate it counter-clockwise to remove it from the lamp. Remove the bulb from the socket. Installation is the reverse of removal.
I think I'd replace the turn signal flasher. It's just a little bi-metal switch and can go bad easily.
Probably either in the "convenience center", located at the driver's side kick panel, or inside the steering column housing.

My Haynes manual says that the "96 turn signal/hazard flasher is plugged into the "convenience center" which is mounted at the top of the left kick panel. FriPilot
This is pretty direct. From inside the trunk, pull the carpeting away from the tail lamp housing. The bulbs are held in place by twist out/in sockets. Twist the socket and remove it from the housing. Pull the old bulb out and throw away. Put in a new bulb and screw the socket back into place. Turn the ignition on and check the turn signal. Replace the carpeting and you're done! FriPilot
On my 2001 it is part of the Hazard switch. You have to replace the entire switch on a 2001.
