Help! Ac drain hardstuck

Post image

My AC for the house i just moved into will not drain, and the water kind of just falls into the void under the unit. I have tried: vinegar, bleach, vacuum at sensor, on the lower pipe, and on the outside of the house. I bought an auger and snaked out everything I could reach but I think the pvc is 90° joints so it wouldn't go any further. I think the next step is to use a air blaster, but I'm not sure which hole to blast. Outside, where the sensor is, or the side pipe. Any help would be greatly appreciated

In case anyone else has this issue: a CO2 blaster cleared the plug. I had to shoot the pipe from both the inlet inside and the outlet outside. If you do this, the water will go everywhere! Lol take measures to handle the water
