The hazard back lights wont quit blinking when car is running even when i pull the fuse on a 2002 buick regal


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.

02 Buick LeSabre Ltd. Rear flashers work (blinking rapidly), front bulbs stay on, inside indicators also flash rapidly. Replaced control module under the dash. Did not help. What else could it be?


Hi there., when flashers/indicators work rapidly on the dashboard you should check whether it is the same on the actual bulds. Fadt flashing is usually a sign of a bulb failure somewhere. If everything is functioning ok externally I would consult a competent technician for a diagnosis.

2000 buick lesabre turn signals dont work but hazard lights do


buicks usually have a separate flasher for each circuit, the flasher for the turn signals should be near the one for the hazards. it will be in the owners manual.

I have a 1992 Buick La Sabre Custom. My brake lights are not working but taillights, turn signals and hazard lights do work. Switch ok. fuse ok. ????????


if your fuse is good. and you have power at the brake light switch and when you hit the brakes you have power coming out the otherside of brake light switch/which would be the white wire/ check that the white wire is sending power up the turn signal switch. if theres power there and your turnsignals work? im afraid that your turnsignal switch is bad rare but it has been known to happen.
