Fig. 2: Ignition switch rod positioning
On non-tilt columns:
Move the ignition switch slider to the OFF unlocked position (move the slider all the way down, then back two clicks). The remote rod hole in the ignition switch slider should now be centered.
Insert the remote rod in the ignition switch slider hole and install the ignition switch on the steering column. Tighten the attaching screws to 35 inch lbs. (4 Nm).
On tilt columns:
Insert the ignition key in the lock cylinder and turn the cylinder to the OFF unlocked position.
Move the ignition switch downward to eliminate any slack and tighten the attaching screws to 35 inch lbs. (4 Nm).
Install any components removed for switch access.
With Air Bag

See Figures 3 through 9

CAUTION
Before performing this procedure, disable the air bag system (refer ). Failure to do so could result in accidental air bag deployment and possible injury.
Disconnect the negative battery cable and disable the air bag system.
If equipped, remove the tilt lever.
Remove the upper and lower steering column covers with a suitable Torx ® driver.
Using Snap-On ® tamper-proof bit TTXR20BO or equivalent, remove the ignition switch screws.

I have followed these directions to the letter. Yet still once I get the switch back together. There seems to be too much free movement when I insert the key and turn it towards the start position. Then once I get to the spring/cranking position it feels like there is less than 1/3 of the original motion than what I had previous to the broken switch. But still not enough movement to crank/start the engine. It basically sits in the "on/run" position.

Upon inspection of the key tumbler itself it does look a bit worn. The amalgamate metal the cylinder is made of appears either worn or possibly broken. I looked inside the column side of the switch housing and saw no broken parts however. Could it be that I need a new key assembly. Please help my 93 GC Laredo is down and I need wheels bad.

Yes. It is very possible that you need a new ignition lock cylinder. Also, check the bushings on the rod that goes to the electrical ignition switch. Also check the rod, it may have been bent.
