Stabilitrak Disabled/Service 4wd

[jtstacy77]

Seems I have some 4wd issues on my 06 1500 4x4 avalanche. Had alot of rain yesterday, got in my truck this morning and traction control light came on, and I got the stabiltrak disabled/service 4wd message. Shut it off a few times and it would not go away. When I started up at work the messages didn't come back on, but the 4wd switch just lit up in neutral, the red light. Restarted it this evening and all messages have disappeared and the 4wd functions properly. My Avalanche is not a Z71 so it does not have the skid plates to keep water from getting to the actuator plugs. Could it be that water got into the plug and dried out as the temp rose today?The reason I ask about the plugs is I have a friend with an 03 sierra that said he kept getting water in the plug. Any suggestions are appreciated!

Possible. Always possible.

I've always filled any electrical connection that I take apart with dielectric grease, keeps the water out for the most part and prevents corrosion.
