Pontiac Repair: water leakage?, power message, panoramic sunroof

Question
I have an 05 G6 GT with a panoramic sunroof, and it apparently may be causing water instrusion to the instrument panel.  Once I noticed wet floorboards, and most recently it triggered the MIL indicator, which shut the engine off while I was driving it.  Assuming the sunroof is the cause, is there a ballpark figure on how expensive this is to fix?  Thank you very much for any help you can offer.

Answer
Hey  J:

it could be a very easy fix if it's just a wet connetor. the drain hoses either plug up on them or fall off the sunroof module and the water runs down the front "A" pillar and gets into a plug for the gas pedal assembly I'll assume you have a reduces engine power message as well. if that is all that happened the plug needs to be cleaned/dried out fix the drain hose and your good to go. I'm figuring 2 hours of labor if the hoses fell off if they are just plugged less time then that. Without seeing it or knowing what codes are set I'm just guessing here but I have seen it many times. good luck :-)
