I think I have read around $300.00 for the dealer to work on it if it needs more than just the drains being cleared out. Search the various boards, there was a father whose daughter bought a used one and it leaked. That is where I think I read the $300.00.
If you've done any searching already, you may know that the earlier models were built with too short of tubes, and became disconnected. GM at one time had a "recall" but I'm sure that has expired. If the previous owner didn't experience the leaks for what ever reason, yours might not have been repaired if it is one of the ones affected.
