this is your mistake, all you will do is suck air that way.
YOU MUST CUT THE LINE TO CLEAR THE BLOCKAGE
we explained several times already that you must suck, or blow, from the line itself, and not the vent.
if this is too hard to understand then call out a repair man and he will do it the way i described to do it.
if there is no blockage then it could be a rotten drain pan inside the unit, but whatever it is, at some point you risk water damage to the ceiling and a huge repair to the damage that will cost

This was happening to mine. My dryer vent pole and roof outlet was malfunctioning. Got it replaced. No more lint in the drip pan.

I put together a big trap (1 1/2" pvc) with a cleanout on the end. Once or twice a year I will stick a hose nozzle on the end of the drain outside. I will give a quick burst and repeat slightly longer each time until I quit getting out the white cold slime bits.

Yeah but mine didn’t have the right kind of vent installed. No lint could get out. DIY job by the former owners tenant

Snake it out

I'll probably get screamed at, but I took an air tank and blew out the line, worked fine. Sometimes algae or dirt daubers or whatever just can't be resolved by clorox.

HVAC TECH HERE, Over amount of water draining can be caused by several factors. YOU MUST change your “normal” filters once a month especially here in Louisiana.
You have to have adequate air flow with no restrictions across your evaporator coil in the attic, ( or closet depending on the age of your system and house.) Depending on how your condenser is cycling and the amount of refrigerant can cause crazy things to occur and throw your troubleshooting abilities into left field chasing your tail.
Some filters are expensive and thick, pleated type about six inches thick. I’m referring to the normal 3/4 inch thick filter you find at stores like Home Depot and such. Call a pro out and have your system inspected and serviced, it can literally save you thousands in the long run., your welcome

So I snaked it out, tried blowing it out with compressed air. Added a cut off valve to make sure I was blowing in the right direction. Had someone else come out and they believe I have a cracked pan.

A cracked pan is causing it not to drain? How is that?
Did you check the level of your pan and hvac system? Make sure to check that? I’ve had a system not be level causing it to not drain properly.

A cracked primary drain pan inside the cased evaporator coil box (one doesn’t see that pan without opening the evaporator coil box) allows the condensate water to leak down into the the secondary “drain” pan that sits below it (I guess overflow or emergency pan would be a better term) and shuts the unit down when the water reaches a depth to activate the emergency shut off switch. Many secondary pans are not plumbed with a drain line, just the emergency shut down switch - mine isn’t.
A cracked primary drain pain is nowhere near as common as a plugged primary drain line but it does occur from time to time.
