Hazard flashers work. shorted the contacts from power to the signal line, can get the signal to work but not with the switch. changed the switch but the same problem. momentary contact, then nothing, on both switches. any ideas on what could be causing this problem? where can i get the wiring for the turn signal for this car? Thanks in advance.
Does the light turn on then not blink? Do all signals do the same thing? Front and rear? Left and right? Electrical problems can be found by tracing problems back from the loads and eliminating them each component in the circuit until you reach the source itself (battery).
Example: Start with the bulbs, replace them. It's cheap. Then inspect the sockets, how are the contacts? Corroded? Burnt? Move on to the wiring, broken? Pinched? Disconnected? Next are the relays in the fuse box. There cheap too, replace those. They can be tested, listen for a click when voltage is applied. Check the fuses in the multiple fuse locations, replace if needed. The switch itself should have been the lst thing since it probably set you back about $80.00 and required the steering wheel tobe removed. This is also called a "multi-function switch". It combines several components for easy replacment, but a higher cost, even if only one thing has failed. (Thank you GM.)

When the turn signals quit working pull up , down , front to back an back to front on the turn signal switch handle . Do they work when doing this ? Pontiac had bad switch . The power for the turn signals goes through the flasher / hazard module . Could be the switch or the module.
The HAZARD LPS fuse in the left hand instrument panel (LH IP) junction block supplies battery positive voltage to the flasher module, which is part of the hazard switch assembly. The TURN LPS fuse in the LH IP junction block supplies ignition positive voltage to the flasher module. The turn signal lamps may only be activated with the ignition switch in the ON position. When the turn signal switch is placed in either the left or right position, current flow is from the flasher module's output to the turn signal switch assembly. The flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators.
The hazzard switch is the most likely culprit since it directs current to either the turn signal switch or directly to the turn signal lights depending on its position. Over time the contacts wear out in the flasher switch. When you push it in and out you are allowing good contact to return to the normally off function that routes power to the turn signal switch.
The flasher switch can be found at any good parts store.
The hazard switch gets power from the horn fuse which is hot all the time, and from the turn signal fuse which is hot when the key switch is on. The turn signal switch gets power from the hazard switch and both use the same flasher. So if the turn signals work but the hazard switch does not power the lights, and both fuses have power, I would say the problem is inside the hazard switch.
check the fuse if good then turn on the hazard lights if they work then you probably need a turn signal flasher which is a separate flasher unit then the hazard one.it usually looks like the hazard one so with the hazards on and locate it then you will know what the signal flasher looks like and you will also know not to change the wrong flasher unit.the signal flasher is often located at or near the under dash fuse panel or somewhere in the dash you don`t say what type of car your talking about.
First of all check the Flasher relay.The other to check is the ground wiring.Is the wiring's proper or getting short.The flasher is clicking in off position this indicates that its actually turning off.the flasher is still receiving any current to function. so the wiring's needs to be checked and confirmed.The wiring procedure in 1999 GMC sierra is as follows:--
The circuit is fairly simple: 12 V power from the ignition relay is brought to the Hazard switch. In the Off position, the 12 v is routed through the Hazard switch to one pin of the flasher. Another pin of the flasher goes to ground. The third pin goes to the turn signal switch, where it is connected to either the left or right signal light circuits. The other side of each bulb is connected to ground. When either the turn signal or Hazard switch is turned on, the current through the flasher causes it open and close its internal contact in the 12 V line, thereby turning the signal lights on and off. So, for the flasher to continue to click when the ignition switch is at ON/OFF (assuming there is no clicking when it is OFF), there must be a connection from the 12 V supply through the flasher and the turn switch. It is possible that there is a wire between the flasher and the turn signal switch that is worn and contacting ground. Thanks. you can rate this solution and show your appreciation.
It is not the flasher if the hazards work, it is 1 flasher for both turn signals and the hazard lamps. It is in a relay block ( along with the blower motor relay ) under the dash, about in line with the steering wheel column ).
Try tilting the steering wheel all the way up, and test again.
The other quick test is to cycle the hazard switch a few times, to see if it cleans the contacts for the turn signal on the MFS,
