how do you fix security switch on a 2002 oldsmobile alero
You have to replace the hazard/turn signal switch located in the center of the dash. Oldsmobile issued a recall for this part in 2004. If it has not been replaced, the dealer will do it for free. If it has been replaced, and failed again (like mine has) you are on your own. Call a dealer to see if it has been replaced yet.
