FNG here, my wife recently bought a 1999 Tahoe and we had a problem crop up with the turn signals. They do not work at all though the hazards are functional. When she tries to use the turn signal the tail light on that side turns off. Brake light and headlight function is not effected. I would like to start with the simple things but I'll be dipped if I can find a fuse for the turn signals. I did find the blinker relay under the drivers side steering column. Any help is vastly appreciated.
