Left turn signal is intermittent. While switching lanes or in need to switch lanes the left turn signal might turn on then completely stop or won't turn on at all. The right turn signal works all the time. The left turn signal will work fine, then out of no where will stop working, then will start working fine. It does this whether the car is moving or stationary, on the highway, streets, or in my garage. The safety concern is when I need to turn it seems like I've changed my mind and might cause an accident.

Three times while driving my Trailblazer, all lights have gone out. The three times did not happen under similar driving conditions. One was while driving on the expressway at 70 mph, one was while exiting a business route at less than 45 mph, the third was while pulling up to a stoplight. I have learned to use the lighting control knob on the console, turning it to the right and back again until the lights come back on. The part of system causing the issue is unknown to me.
