Replace hazard switch behind dash

YOU HAVE TO REMOVE THE CENTER INSTRUMENT PANEL BEZEL TO REPLACE THE HAZARD SWITCH.

The signal lights and hazard flashers work off of separate plug in modules generally easy to get to under the dash behind the steering wheel area. With the blinkers on you can touch the module and feel the clicking inside. Look for a black or blue square boxy looking thing with three or two terminals coming out of it, about the size of a golf ball. One will be for hazards and one for blinkers. Ask at the parts store for the turn signal blinker module and then replace either one first to test to see if it corrects the problem and if it doesn't, put the old module back in place and replace the other with the new one (if they appear identical - interchangeable).

Those are the typical symptoms of a problem with the mutifunction switch. The dielectric grease becomes impregnated with metal flakes, which jumps the contacts inside the switch. The clicking that you hear is the flasher relay located behind the glove compartment. Replacing the switch is not that hard for a DIYer. Some guys have remedied the problem by taking the switch apart, cleaning out the old grease, and applying new grease.

www.rockautpparts.com part number 1S8422 Hazard Warning Switch. $33.96 total cost. My 2002 Alero had switch in dash, not part of grill. Had to remove speedometer bezel and speedometer. Then take two small straight slots to put on holder to push tabs down to release. Patience is a virtue on this.

i have a 2000 and you gotta replace the hazard light switch due to the company used cheap products and it shorts out your signal lights...usually costs around 200

In Olds Alero the flasher is intergrated into the hazard light button. It is all one assembly in the dash. It is in the $40 dollar range, but that is the only way to fix the flashers is to replace assembly. You must remove the plastic housing from around the dash cluster to reach. It is located to the right of the dash cluster. If you are good with your hands you will be able to get it out without taking out the cluster. Be careful, it is held in place with plastic snaps. Part number is on the assembly and it is GM exclusive.
