Jeep Repair: Seat Heater and water leaking under passenger carpet. AC makes passenger window for. Water is clean, not antifreese

Question
QUESTION: 2001 Cherokee Limited.  Driver seat heater, like so many, inoperative.  Chrysler no longer stocks replacement parts.  Switch flashes but no heat.  Passenger seat works fine. Does anyone stock NOS parts for seat heater? Additionally, I have leak of clean water under the passenger carpet.  Windshield replaced and sealed.  No help.  If I leave car out in rain, no leak.  Run AC...leak.  Fogs windows. Can this be AC drain?  If so, where is the drain hose connected to expansion coil?  And if I can find it, is it easy to replace or clear?   Finally, I found a rear window wiper/washer switch, NOS, on line.  Can I remove the old switch without pulling the control panel?  I will pay dearly for this advice!  Really!

ANSWER: Grand Cherokee  or little box Cherokee?
