First you have to remove the panel from the bottom of the dash board to be able to get to the steering column bolts. Then, disconnect all of the wiring harnesses from the steering column. After this, go underneath the truck and disconnect the shifter linkage from the transmission. You can then remove the four bolts that hold the column up. Then, carefully slide the column out. Once the shifter linkage is against the firewall, rotate the column until you can pull the linkage through the opening in the firewall.
It is possible to drive a Chevy Trailblazer with no power steering. However, it isn't recommended. The steering column could freeze and there could be no way to steer the car.
My 93 has it under and to the right of steering column but it's a right hand drive.
Try changing the ignition switch located on the steering column
To adjust the drive or gear indicator on the steering column of a 1996 Oldsmobile Ciera, first, ensure the vehicle is in park and turned off. Carefully remove the steering column cover to access the gear indicator mechanism. Locate the adjustment screw or tab connected to the gear indicator, and align it with the correct gear position as indicated on the shift lever. Reassemble the column cover and test the indicator to ensure it accurately reflects the selected gear.
