Re: water leaking from A/C
Ok this unit should have a silicone seal around the pan so water does not collect under it if old silicone is worn away scrape old silicone away and redo new silicone around unit so it sits properly make sure all the water is gone before sealing because you run the risk of mold build up under it; let it dry or help it dry thats up to you
but would like little more info on what this is on

That depends upon the cause of the water. There are a few possibilities, depending upon the vehicle. See this list and use what applies as a way to narrow down the source.
1. Rust hole in floorboard. Only way to fix is to repair hole.
2. Leaking door seal on passenger side. Locate and repair leaking seal.
3. Leaking sun/moon roof. Some vehicles that have these run their drain lines down the passenger side door pillar and down thru the floor pan. Sometimes the hose shrinks with age or breaks and allow water to get on to the floor. Remove the passenger side kick panel and inspect and repair as needed.
4. Leaking heater core. Feel and smell the water. If it smells like antifreeze or has an oily feel, it may be coolant leaking from the heater core. Of course there should be a loss of coolant associated with this problem. Here the only solution is to bypass or replace the heater core.
5. Leaking windshield seal. Most car windshields today are glued into place. These glue joints can break loose and allow water to leak. Also, rust can form around the windshield seal and cause rust holes that can leak. Lastly, extremely high-powered car stereo systems that pump mega-bass can cause overpressure inside the vehicle that can cause the seal of the glass to separate.
Sounds like base gasket at roof is loose or defective to start with. Try removing ceiling assembly enough to tighten 4 bolts that secure roof unit to inside bracket. Do not compress too much, just snug them all evenly and see if water slows or stops. If not, you will have to remove upper unit (roof) and replace gasket and re-secure but don't tighten to excessive, only compress gasket approx half of original thickness. Also make sure upper unit is aligned properly with opening of roof.
The roof A/C unit has a foam rubber seal/one piece gasket that fits around the part you see inside the coach but must be put in pklace before the unit is inserted in the roof opening. Replacing is relatively easy but you will need to remove the interior trim Disconnect the wiring from the coach to the unit and remove the four bolts holding the unit in place. Then lift out the A/C.to replace the seal. They do leak because of age and compression by units weight. Good Luck
If you remove the air grill for the inside part you will find four screws which when tightened compress the seal gasket under the outside to roof. It may be a case of these screws being somewhat loose.
