I have chevrolet trailblazer 2006. The right side reverse light is not working. I checked the bulb but it is fine. I could not figure out where is the fuse. Can someone help me out with this issue

Check for power at socket between the two wires when other light is on. If power is there. Make sure bulb tip is clean and no green tarnish is present. Apply bulb lube on bulb and try it again. If still won't come on then try new bulb. If no power is present when you check socket check each wire with one probe of meter to ground. One should show 12 volts to ground. If one does have power check the other for continuity to ground if none found check grounding of that wire to frame.

I'm sorry you're having troubles with your lights sasimaskari. After looking in your OM, I discovered what I think you're looking for located in the Engine Compartment Fuse Block in position 4. I hope this helps you resolve the issue. Marlea Wilson GM Customer Care

I looked and found a Fuse in the front fuse box,not actually in the box but in front of the box it looks like a flat piece of metal mounted between two bolts it also brought back all power to rear fuse box ,now all inside works too,Congradulations
