Loose body control module connectors will crop all kinds of problems other than than just the steering lock problems.
The one thing to check if the right hand connector with the wire loom coming back under the passenger carpet area, since if the wire loom is too tight, then someone sitting in the passenger seat can cause the connector to become loose again.
So on that note, make sure that the wire looms before the connectors have some extra slack, and not the reason that they are coming loose instead.
As for dielectric grease, after you have used contact cleaner on both the connectors and pins, if the problem is not the wire looms too tight, then you better check the A/C air box drain vent to make sure it's not plugged and why you are getting moisture in the BCM area to cause problems. Not only can that mosture wreck havoc on the connectors, but the connections inside the Body control module as well.
The A/C drain pipe is located under the cabin air filter door on the fire wall, and just use a small piece of wire up the bottom of the tube exit hole to see if it plugged (or you can pull the hose off if it really plugged up with debris and needs to be cleaned if it turns out the bottom of your AC box can second as a trout farm from not correctly draining).
Lastly, get under the car and check the tape that GM installs on the Jig point channels of the body they use to put the car together at the factory (drop the body down on the rolling frame). If the tape is falling off, it opens the jig alignment holes to allow water to flush back inside the car from the bottom of the car.
