Default A/c condensation water leaking help

I have water leaking down onto the passenger footwell.I believe the condensation from A/C is causing the problem.Last night I was stuck with column lock service ,pull key wait 10 sec.,and this one I never seen before TONNEAU AJAR.
Now I know, water dripping down on the BCM can cause problems.Two days prior to this I removed the A/C blower motor because it was locking up.I lubricated it and all was fine.Reinstalled it and now have this problem with it.
What is causing so much water to built up.
Keep in mind this car does not see rain.
Codes that appear BCM 0502,0507,2527,2589,2588,2723
I pulled the seat out and rug out so that it can dry up
I also did one day prior to this was change out my oil sensor removing the intake throttle body. Could anything from this be cause.

You have a blocked A/C drain. The link above shows you what to do. Make sure you dry out the BCM with a hair dryer.

When the drain is blocked the condensation comes out the bottom of the blower.

I have the same issue so lets combine threads here. The service manual show the a/c condensor drain tube to be a small 5/8 or so outlet behind the right side head on the firewall it has a 90 degree rubber drain hose on it directing the flow out and down. My hose is missing but water is coming from the hole. My theory was the air at speed is blowing the water back into the cab with the drain hose missing. Are you guys saying the udder behind the battery also drains from the a/c? It does appear the water is coming more from that area above the bcm and fuse panel. I will clean it also and see what happens.
