2003 Buick LeSabre Q&A
2003 Buick LeSabre Question: My right brake will not work at all, even after I changed the bulb. How to fix?
Does the signal still light work? If so then possible/more likely the multifunction switch is defective!! If signal light DOESN'T work either, check in trunk for a wire problem, if none found, replace the bulb socket. Brake light circuits go through the sig. light (multi) switch before going to rear lights and either left, right or both can be inop. if the switch is defective! Weird I know. - pushrod
