The cold evaporator will collect condensed moisture and the condensation normaly drains out the condensation drain path.
As the evaporator fins sweat, dust and particles get stuck to the moisture and fins. Dirty evaporator fins hold more moisture than clean fins. As air rushes thru the fins, moisture is blown off.
It is important to maintain clean air filters, and to treat the evaporator with evaporator cleaner as needed. The outdoor condenser also needs free air flow, periodic cleaning.
It is normal for alga to form and clog condensation pans and drains, periodic cleaning is part of their maintenance too.
There are dedicated chemicals for the maintenance of severely contaminated situations, use as directed. I prefer flushing out clean with a garden hose, persistent alga needs chemicals in cake form or spray, use as prescribed by the product.

Your indoor unit pc board is bad, replace it.

The first problem sounds like the wiring is wrong up at the heating unit not turning on the blower fan in the heater when you call for cooling. Most typical is either something has chewed the wires or the wires have been stripped b something else. The AC not cooling your house can be either it is low on freon or the system is to small for your house. Also check your filter and make sure that it is not blocked and everything is clean with the filter

take the dash off to see if the vents are connected to the dash. if not, the heat from the engine is blowing through the open hole

Same exact problem started for us last night. (Same model, installed by me about four+ years ago) Water was really coming out of the weep hole, and didn't stop until I shut it off at the valve. This happened once before, and all I had to do was clean the drain line adapter, because it gets full of gunk from the disposal over time. But this time that did not do the trick. (Plus there was not all that much gunk this time....) So I was baffled for awhile but came up with this solution.
I hooked up a small length of clear tubing to my cheap-o tire inflater/air compressor. Put the clear tube against the weep hole. Turned on the compressor, and VOILA!, a bunch of gunk that was clogging the drain tube came out. I think when this tube, or the drain line adapter gets clogged, it causes water to go out the weep hole instead of down the drain. (If you don't have a small compressor, then theoretically there is enough air pressure from something like a
bicycle pump, and this solution *might* work with one of those. But if you try this, of course only use the DOWNWARD
(air-going-outward) pump action...pulling up (inward) would force the clog deeper up the
drain tube)
SOURCE: there is no drain hole for water to drip outside.
These are designed to retain some water in the pan. This is for the slinger fan to throw water through the condensing coil. This helps the refrigerant cool and is important to the efficiency of the unit. I would certainly not recommend drilling a hole in the bottom. The hole may cause the water to roll somewhere where damage could occur. Try instead tipping the unit Backwards before bringing it in the house.
