driver side back lights

[lazyrandy]

2008 suburban when the headlights are on, and left turn signal activated, both back up lights come on, when I step on the brake, with the lights on, reverse lights come on and entire driver side brake lights go off, any thoughts?

Check the turn signal relay module.. remove driver side knee booster trim panel thats below the steeing wheel it has two 7mm hex screws at the lower end of the trim panel then pull straight toward driver seat to remove you should be able to see the I/Pfuse block .. at the back of the fuse block you will see a 3 inch long and 1 inch wide square looking black box thats the relay module you have to get a pretty good grip on it. . It pulls right out or get a little screw driver to help pry it out if needed

Hey randy I gave you the wrong info don't know what I was thinking for some reason I thought we were talking about a 2000 Suburban sorry about that now on your 08 look first for a bad ground coming off the left rear tail lamp harness connector assy... if the grund is ok then im gonna have to say possibly a internally shorted Body Control Module.. but one other thing you might want to check is the bulbs themselves make sure that the filaments aren't shorting out and causing some sort of an electrical feed back..
