Turn signals and hazard flashers quit working

Turn Signal Lamps
The TSIG/HAZ fuse in the rear fuse block supplies battery positive voltage to the flasher module. The module is part of the hazard switch assembly. The flasher module has ground at G201. The turn signal lamps may only be activated with the ignition switch in the ON or START position. The IGN-1 fuse in the rear fuse block supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flows from the turn signal switch assembly to the flasher module. The 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, the switch contacts are close and the turn signal/hazard flasher module hazard input is grounded. In response to this input, the turn signal/hazard flasher module supplies battery positive voltage in an on and off flashing pattern to all the turn signal lamps. This also activates both turn signal indicators. When a THEFT is occurring, the DIM grounds the turn signal/hazard flasher module hazard input. The left turn signals have ground at G401 and at G402. The right turn signals have ground at G401.

The flasher units are different for turn signals and four way flashers. Not sure but most are under the dash not far from the steering column

Use same flasher problem is either fuse or switch

First check turn signal fuse and relay if, they are good then try pressing on and off the hazard switch while turning the signal switch on.If signals start to work replace hazard switch.If hazard switch is good then replace turn signal switch.

If the fuses are good and the front and rear bulbs are good, change the flasher for the turn signals, even tho the right is working. If that doesn't fix the problem, it might be in the turn sgnal switch on the steering column.
If both bulbs are good for the backup lights and fuses are good, then the backup light switch, which is screwed into the side of the transmission has to bad.

You may want to try and replace your flasher...not the fuse.




Costs about $11.00

i have a similar problem but my left signal works, when i turn the right on it just does an annoying buzz sound. if you can think of any explination for such shinanogins help would be greatly appreciated

please check your flasher relay. it is normally a three prong relay box.


tnx 4 using fixya,

drcool

the actual hazard lights switch is also a relay and linked to signals left/right try checking this out ?

There are two possible locations for the relay.

First in the fuse panel, close to the bottom.

Second, in some models they put the darn thing behind the dash in the center of the car, it's a real pain to get to if it's that one.

Good luck
