I have a 2000 buick lesabre. The signal lights arent working, however the hazzard lights do flash when turned on. I have checked the fuses I know to check and all the bulbs are working. However when the turn signal switch on the steering column is pushed up or down to activate the turn signals they do not work. Can you tell me how to go about fixing this problem?
In the diagram, the yellow wire is voltage for turn signals, purple wire is voltage for taillamps, Black wire is ground. If turn voltage, you have to check feed to and from the turn/hazzard module. That module receives a signal from turn switch.
