Keith,
Unfortunately my coach is at a repair facility getting my last $ worth out of an expiring warrantee policy. If the center console is anything like the one in my 00 Marquis, it is very difficult to remove as it had the weight of the dash on it. Post a pix or 2 and maybe one of us can see a way to access the exchanger w/o a cabinet removal. If you haven't yet, clamp the hose to prevent more leakage.
