check the fuses..
Yes, the ignition on a trailblazer can cause head lights to work improperly.
Check the fuseable link.
If you brake lights are not working on your trailblazer it could be due to a number of reasons. Your fuse could be blown, or your light may no longer work.
None of the interior lights work so I think it might be a fuse?
If you mean the courtesy lights on the ceiling, check them both and make sure the switch on the light itself is set to "door". They both have a switch that says "OFF/ON/DOOR".
If only the interior lights won't work, check the fuses.

Check your fuses - they are operated separately
The lights may not work because the wires for the lights is not pluged in or you blew a fuse.
In a 1987 Cadillac Brougham Fleetwood, the fuse for the interior lights is typically located in the fuse panel, which is usually found under the dashboard on the driver's side or in the engine compartment. You can check the owner’s manual for the exact location and layout of the fuse panel. Look for a fuse labeled "Dome" or "Interior Lights" and inspect it for any signs of damage or a break. If it’s blown, replacing it should restore the functionality of the interior lights.
