Thanks for the info, Blue. I think I may have figured out what my service 4wd system message is for. I took the actuator out took it apart and cleaned it real good and put it back in. Went for a drive heard a loud band and it shut off. I put it in neutral and started it back up. When I went into reverse I had no reverse and a loud gridning noise. I removed the actuator and manually shifted it all the way towards the back and now I have all gears back. So I'm assuming my transfer case is shot? Also I want to make sure that i do I'm fact have the transfer case shifted into the correct position as I don't want it to just be in rear wheel drive or 4 low. It runs and drives like it did before and no shifting issues. Is there any way to confirm I have the transfer case in the correct position? I'm not even sure if the transfer case can be put into any other position other than 4 low neutral or regal awd but I'd like to know for sure. I stood on the brakes and I can't break the rears loose so I'm assuming it's shifted correctly.
Edit: sunroof leak was from clogged drains. I removed the sun roof and cleaned them out and it drains fine now. My sunroof is broken I can only get the vent to work. Anything else and it binds up. Not sure what reputable source sells the sunroof kit.

; Has your Commander ever had the P73 campaign completed? Read the attached .PDF; This will cause the service 4WD System message that you have currently;
The difference between a safety recall and a campaign is this; a safety recall pertains to a vehicle problem that is a safety concern; a campaign is a vehicle problem that is not a safety concern, but, pertains to customer satisfaction.
Also just to clarify for anybody else who may be reading this; I don't care for the way they've worded the P73 campaign where they state; "2006 through 2010 model year Jeepģ Commander vehicles equipped with a Quadra-Trac II Full Time Active 4WD transfer case. "
Because it can be confusing to a new owner who doesn't know Jeeps or Commanders very well.
The P73 campaign applies to all 2006-2010 Commanders with the NV245 two speed transfer case, which means all Commanders with the Quadra-Trac II & Quadra-Drive II
4WD systems, because both systems use the same exact transfer case. This is how they should have worded it - instead of saying "Commander vehicles equipped with a Quadra-Trac II Full Time Active 4WD transfer case." That's a terrible and misleading choice of words.
If the P73 campaign doesn't solve your issue, the next thing I'd look at is a bad transfer case actuator motor; A bad transfer case actuator motor can cause you to lose the ability to shift into, or out of, 4-LOW depending on which mode you are in when it decides to fail.
