There is a part on the unit that seems to act like
Under the cover of the condenser area there is a part on the unit that seems to act like a switch, when I turn on the ac it clacks and sparks. I can tap on it or apply pressure to it and the unit will engage cooling. there seems to be a short of some sort from an orange wire that is attached to the top/side of the switch and attaches to something else next to it. If I new what these parts were, they look simple to replace. Any suggestions?

remove cover and filter and using a sprayer bottle with a water and mild soap mix spray the coils dont wipe them you will damage unit plus probably get injured spray really well let sit for a few minutes than turn on fan and start spraying again the fan will draw the solution throught the coil and the solution will also clean down condensation pan and then drain out back --other problem would be a bird or critter took up living by the condenser and you will need to remove the frame cover to access that area
I assume there are no leaks in the windows or sunroof.
One probable cause, is the Air Conditioning unit. On all cars there is a drain line for the AC unit. As a unit runs, it produces condensation. (Just as a bottle of cold water produces condensation in a warm, humid area). That water has to go somewhere, so there is a drain at the bottom of the system. That drain (which comes out under the car, usually centered under the dashboard area), can become clogged or pinched and leave the water to accumulate in the system base, (again inside the car, under the dash). When this happens, the water will seep under the carpet and find the lowest area, which in this case, is the floorboard in the back seat area.
Sounds like your drains for drip pan under the evaporator area are plugged. They are located at the base of the AC unit on roof. Look real close under AC unit near front, for a hole in base plate of AC on each side. Water ( condensation ) should be dripping out of those holes pretty steady when running. You should have an inch or so clearance between base of AC and roof to try and get a bent piece of wire, or similar in to hole and try to clean it out. If that doesn't help you will have to remove plastic cover and remove all the screws that hold the front cover over the evaporator and remove the front metal cover. Look down at base of the coils and fins and you will see a drip pan that has small holes at each end for drainage. They will get plugged up with debris, thus poor, if any drainage. I use a long air nozzle and a small compressor to blow them and the tray out to clean it well. That will usually cure your problem. Please remember to shut all power to AC, off at breaker panel before removing the cover on roof to avoid electrical shock.
Hi, this is a 10 ton a/c unit, more then likely has 2 stages of cooling. You say the copper suction line is wrapped with insulation already, and the problems continue? What you need to do next as the evaporator coils are in the ceiling, is to have a condensation pan made to cover the bottom of the unit to catch any moisture that drips from the suction line and evaporator coils and have a 3/4" drain that will drain into existing condensate line. You can't prevent the suction line from sweating has thee cold temperatures are reaching its dew point and will always drip. The line should be wrapped with a black cork type insulation that has a sticky back that is made for this suction line. All you can do is have a sheet metal pan made to put under this unit to catch the moisture and let it drain or evaporate if its not real bad. I have seen this many times with units that are in the ceiling, which will destroy the tiles. Keep in mind that the suction line will reach temperatures of 40*F and will drip condensation when it is cooling so they should have put a pan under this unit when it was installed. This will solve the problem, and that's about all that you can do. Please don't forget to rate me as I know you will be kind. I wish I had other ways to solve this, but this is the only way, and the way it should have been done to begin with. Sincerely, Shastalaker7 A/C, Heating, & Refrigeration Contractor
These units do not have condensation "hoses", they have an evaporator pan than is located under the evaporator coil and catches the condensation and then lets it drip down onto the roof and then off the RV. If your AC is leaking into the inside, remove the inner shroud and feel up into the evaporator area for the pan. If it is full, then the drain holes are plugged. They are not easy to get to. Remove the upper shroud and then remove the front cover over the evaporator. At the base of this area is the pan, on each end is the drain hole. Clean them out and all should be fine.
there is only one thing that leaks water there, that is the AC condensation drain, water forms as part of the AC cooling the evaporator core, this water must be drained away or it will flood onto passenger area, so there is a drain on the passenger side at bottom of firewall, will leak allot of water depending on how humid the air is.
My 1988 Nissan AC quit working soon after having the compressor & ect replaced. AC Tecnition took the switch box out from under the dash and cleaned it. He also fixed a loose wire in it. He said this cars switch box calcimates and does not make good contact. AC works great.
