Turn Signal Fuse or switch replacement? '93 buick lesabre?

What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

there is a flasher under the dash put your 4 ways on and listen for the tick noise find the flasher unit under dash area driver side there is two one for the 4 ways and 1 for turn signals now that you have found them turn on working signal touch the flasher unit you will feel it pulse and hear the noise when you have the one pulseing on working signal this will need replacing can also be in fuse area have a good day

The easiest thing for you to do would be to replace the bulbs that are on that circuit. You should have one or two bulbs with a double filament, one for the brake and turn signal and one for the tail light.
If that does not fix the problem, someone will need to check the circuit for power from the turn signal switch. It takes all of the lights on one side to make the turn signal flash.

Some of older cars used 2 seperate flashers one for the signals and one for the hazards.

the turn signal flasher is a small canister-shaped or rectangular unit located under the dash, either in a clip adjacent to the steering column or in the convenience center which is located located under the right side of the dashboard and houses relays and other components. The fuse.faulty flasher unit a broken switch or a loose or open wire. We have eliminated the switch, I would check all fuses inside and out, you can replace the flasher with the hazard flasher as if I remember correctly they are the same shape and size, then it is just a matter with a tester light running it from the column to the sockets and finding the break. Hope this helps Tim

chack under the hood for the fuse box,under the fuse box you should have the description of all fuses,search for the one saying turn lamp,and test it with a multimeter or by eye sight,if its burn replace

check the front kick pannel for it or try this if and when you can get it to work listen for it clicking and that will tell you were it is

I know this will sound Stupid. Get back inside to the Bulb that you Replaced and Turn it Over. Some of these Bulbs will only work if they are in a Certain way. Have that Side Blinker Going when you are Messing with the Bulb to Minimize the Work load on thisPlease Rate my Response, I need all the Help That I can Get! Thanks! Job.

There is a Turn Signal "Flasher" that should be on the Fuse Panel inside the Car. If not it will be in the Fuse Relay Box under the Hood. This is the Problem and needs to be Replaced. Let me know if you need more Help! Please Rate my Response, I need all the Help I can get! Thanks!

Have you tried replacing the flasher? They're typically round, and with the fuses under/in the dash. They probably cost 10-15 bucks, usually available at your local autoparts store.
