see WIRING, (end)
8w-51/52
chapter 8w, page 51-4 shows the switch. (complex it is)
note how brake and turns are shared, resources. (blub elements)
now 8w-52-6
see the flasher module.
see C305 pin 2, any load on that pin will cause it to flash.(inside)
that would be any switch in the combo switch stuck on.

yes

your car has a bad hazard 4-way switch
remove the dash bezzle around the switch
plug the new one in
should fix your turn signals and 4-way flashers

Flasher you should find an round flasher in your fuse box. --> Application:
With 2 terminals
Notes: ( Autozone has this part # LL552)
Electronic

If you mean the left turn signal indicator on the dashboard won't blink...sometimes means the actual bulb for your left blinker is out. If you mean the actual exterior blinker bulbs don't blink...may be the flasher.

The flasher is located above the fuse panel. The relays are built into the switch itself. They have a recall on the 4 way flasher switch because it is faulty and causes blinkers not to turn on. Very common Malibu and other Gm problem

try changing the peanut bulb underneath the main flasher as they should alternate when one is on the other is off & so on..

No Turn Signal Operation (blinker)The turn signal lights in your car are a basic electrical system that controls the front and rear blinker lights to alert the intended direction of the vehicle. We have listed some of the most common problems and repair troubleshooting tips below:
Troubleshooting Procedure
To start troubleshooting this problem:

• Turn the key to the on position (do not start engine)
  
• Inspect the system fuse located in the fuse panel and replace if needed. If you cannot find the location of the blinker fuse consult your owner's manual or an online repair manual
  
• When a blinker flasher fails it can cause blinker lights to say on, not blink, or not go on at all. To test the blinker system flasher, remove the flasher unit and insert a jumper wire between the two terminals. If blinker stays on in both directions without blinking, replace the flasher. If you cannot find the location of the blinker flasher consult your owners manual or an online repair manual.

the switch in the column has dirt in it or is coming apart most likely.always replace bulbs and flasher(s)
first ,then column switch before spending any money on signal diagnosis. for 15$for bulbs,flasher,20-40$switch,you 90%would have solved problem. gino r.

If you got an owners manual it should tell you in there the location of the flasher. if no manual it should around where the fuse box is.
