Dash lights not coming on, second cig lighter not working(one on right), no air coming out of upper air vents. Checked fuse, Ok replaced anyway. May have overloaded that circuit because I had problems with an accessory blowing fuses in the other cig lighters front and rear. Is there a relay or something that needs to be replace?

Dash lights working fine now. Still issues with cig lighters. The left front one blows a fuse when I plug in an accessory that takes quite a bit of power to run and the right front one is still not working. I have no problem running the accessory of the rear seat cig lighter without blowing that fuse. Upper air vets not pushing air. Trying to find the fuse for the additional front cig lighter but not sure which one it might be. Apparently it has a separate fuse from the other front one.
What was the issue. My dash light come on but gages sometimes don't power up along with ac blower motor and radio door locks and windows

Tailgate lock constantly trying to lock
Chevrolet Trailblazer 2006 LS EXT 4.2 2WD 176000 miles
When starting driving, car auto locks and the tailgate lock keeps trying to lock. I hear it actuating. It stops after a few minutes. On occasions have failed to open after the drive. Relay issue maybe?
